MASTER THE POWERS OF LIGHT is an original method of lighting design imagined by ScenoLight Atelier breaking down our approach into five domains of expertise that guide us to master the light phenomenon and its powers applied to space.

The Powers of Light

We have defined five key powers of light that are always applied in space design, dim up and down to create the perfect balance or overlapping and variable in a space.

FUNCTIONNALITY | The primary power of light is enabling legibility, for our safety in movements also our activities and tasks executions.

ENHANCEMENT | We perceive our environment because there is light, a power applies to emphasis space and transform his appearance.

COMFORT | Light impacts our mood and health, a power to control for adequate atmosphere while insuring our welfare and the environment preservation.

ATTRACTIVITY | Light is the most powerful eye catcher, essential for communication and to be memorable yet iconic.

EXPERIENCE | Light generates emotions and stimulates our imagination, a power used to convey stories and produce spectacular.

For this complex manipulation of the invisible we have created a range of creative and technical design pillars structured to control the light phenomenon and its powers.

The Light Phenomenon Unveiled

Lighting is one of the most fascinating phenomena known to humankind, playing a critical role in how we perceive and experience the world around us. As lighting designers this phenomenon is the backbone of our know-how.

But how this phenomenon exactly happens:

1. First a flux of energy is emitted from a powered system to spray into space, generally quantified at source in lumen.

2. Then the light waves impact matter, whose quantity is expressed in Lux / sqm, the illumination sequence.

3. Finally, these waves are reflected with alteration before being intercepted by our eyes, quantified in Candela this is the luminance sequence that activates our vision.

Major factors play a key role in how we perceive space: the lumen flux properties, the matter characteristics, and our vision abilities, so considering only Lux levels as targets is not sufficient. To truly capture the essence of space, we’ve developed an array of expertise that encompasses every aspect of the light phenomenon, and that guarantees accurate and creative lighting design for a lasting impact.

The Captivating Connection Between Lighting and Emotion

Flame is the origin of artificial light, and the origin of animated shadows, generating new images that stimulate the imagination.

Since then, light is linked to our common culture and emotional memories, as dark represents unknown and fear, light shows us the way and it’s safe.

The scale of human emotion is large and diverse, from a subtle sensation to memorable impression. It requires a sensitive knowledge about the psychological role of light to translate a mood into spatial atmosphere, and a talent for narration to convey stories with light that we manage with our expertise in scenography.

We master a powerful aspect of light to create emotions and develop imaginary, a key role in the sensory aspects of space design and the main one for experiential projects.

Prioritizing Health Through Thoughtful Lighting

The rhythm of sunlight is crucial for the balance of our life and our natural environment, with tempos scheduled on the constant evolution of light directions, color temperature and intensity. However, when this rhythm is disrupted, negative consequences, even extinction, can occur.

Artificial light, when done right, can mimic the benefits of natural light through a circadian rhythm approach, with great applications in the fields of wellness. But light also has invisible wavelengths and can generate light pollution. That’s why it’s essential to design lighting systems carefully, minimizing harmful effects on both our bodies and the environment.

Our expertise in this field encompasses various aspects, including managing color temperature, reducing glare, controlling luminance levels, ensuring high-quality light sources, and implementing effective control systems. We stay abreast of scientific research and technological advancements to strike the perfect balance between human needs and preserving the beauty of the natural night sky – a mesmerizing expression of light that everyone should have the chance to experience.

Reveal the Matter with Light.

Light is intangible and invisible, we “see the light” only through its interaction with matter, where materials, colors and textures interfere to finally reveal the physical space.

Our design approach merge light and matter, and the results are endless to reveal and transform our space perception: Play of colors, mirror effects, textures modeling, patterns projections, etc.

Lighting design mastering is then a lot about materials and color expertise, a combination of scientific knowledge and experimental process that allows us to push the limit of perfection to magnify space and generate wonder with the play of light.

Transforming Space Perception with Light

Our perception of space is shaped by the interplay of light and shadows. By understanding how light interacts with volumes, we have the ability to manipulate our perception of the world around us. To unlock the full potential of this dynamic duo, we’ve developed a three-step process.

First, we carefully sculpt the shadows and shades in a three-dimensional space, considering factors like illumination levels and light direction. Then, we strategically place the light source to achieve the desired effect, considering the unique characteristics of the space. Finally, we explore different approaches to integrating the lighting fixture itself, whether it’s hidden, seamlessly integrated, accentuated as a structural element, or used as an ornamental piece.

Merging light and space requires us to master both the intangible and tangible. Our expertise in architecture and scenography allows us to fully comprehend space and infuse theatrical illuminations effects, while our technical knowledge ensures precise and creative integration of light.

Light & Technology

Ultimately the lighting quality relies widely on the technology involved, that includes the luminaires, the control devices, cabling, and multiple accessories. This package is one of the most advanced technological sets in a project, with a concentration of more than thirty properties, specifications and certifications covering electrical, mechanical, optical, and electronic.

Our expertise in this field requires special scientific knowledge for our lighting engineers to analyze and test the products we apply in our design. Technology evolving constantly, we also keep track of the scientific research and manufacturers updates to understand the market evolution and to bring to our clients a clearer view between what is mostly trendy and what is established and durable.

Mastering lighting technology means for us providing the best solution that will fulfill together the design intents goals, the operational requirements, the maintenance constraints, and the budget

The design Process.

We have established three big sequences that rhythm our design process and involvement in a project.

The conceptual period first, from the context and program analysis till the approval of the strategy, the overall concept, and the budget target, in coordination with the other consultants with whom we link the overall nighttime experience from outdoor to indoor.

Then the technical period elevates the project to details drawings and documentation, in coordination with the electrical engineer to power and control our system, and with the operator and investor regarding the selection of the lighting and control solution. The final documents are formatted as tender documentation.

Finally, we ensure authorship supervision during the construction period, including shop drawings review and site visits at key stages. We also adjust the dimming schedules that will generate the lighting scenes, and we create original programming and media contents.

These three sequences can be divided up to a five phases mission, according to the scale and complexity of the project. We strongly advise involving us from concept till completion to ensure the reach of all project targets, and for the mastering of our art till the project is turn on!

Light Up the City: Dien Hong Park and Its Innovative Lighting Design Solutions

Lighting design is an essential component of creating a comfortable and inviting atmosphere in any space. When it comes to designing public spaces such as parks, the lighting plays an even more critical role in creating an environment that encourages people to come and enjoy the surroundings. Recently, our team of lighting designers had the opportunity to work on a unique project in the heart of Hanoi – a public park that required not only improved aesthetics but also a focus on the overall night-time atmosphere and the comfort of the visitors. In this blog post, we will take you through our journey of developing the perfect lighting strategy for this project.

The park in question was situated in the heart of the city and had a beautiful, iconic fountain that the city’s inhabitants adored. Our challenge was to integrate the newly designed lighting elements into the existing urban design while also ensuring that the overall aesthetics and comfort of the park were not disturbed. We started analyzing the site and the architecture’s context, which allowed us to craft a lighting concept that would enhance both the heritage of the site and the new urban design.

Our team put on the ‘theatrical lighting’ hat, focusing on creating a sense of drama and emotion in every area of the park. The iconic fountain was at the heart of this strategy. The fountain’s significance was highlighted by providing an architectural lighting solution that best enhances its aesthetical features and creates a visual stage, inviting visitors to come up close and appreciate it. The sense of theatricality and drama that we created drew visitors into the park and encouraged them to spend more time exploring its unique nighttime atmosphere.

One of our primary objectives was to ensure people’s comfort. Visitors need to feel safe and relaxed in the park’s environment, which is why we designed a lighting system that provides ample light to allow people to see comfortably while also offering an intimate and tranquil atmosphere that invites them to relax, socialize, and engage in different recreational activities within the park after sunset. With that, our lighting design created a balance between functional and comforting lighting that brought the park to life at night.

To integrate the lighting elements seamlessly into the park’s overall design, we collaborated with the park’s architect from DESO Architects. Together, we developed a vision for the park that balanced its historic significance and modern design through the lighting’s use. We also worked closely with landscape designers to ensure that the lighting solutions we proposed were natural-looking and complemented the park’s aesthetic elements such as trees, shrubs, and flowers.

Our project was successful as it delivered a completely new experience for the park’s inhabitants that was unique, beautiful and inviting. The lighting design brought life to the park after dark, enhancing its ambiance and comfort for the visitors. Theatrical lighting added drama and a sense of vibrancy that made the park a destination worth exploring at night. Additionally, the lighting concept harmoniously integrated the new urban design elements into the park’s existing heritage, creating a cohesive and attractive atmosphere that visitors would remember.

The successful implementation of the project demonstrated how critical lighting design is in making public spaces more inviting and comfortable at night. Our team’s approach of implementing a theatrical lighting concept that focused on the overall welfare of visitors and harmoniously integrating it into the park’s existing architectural design proved successful and contributed immensely to the project’s overall success. We believe that every public space should focus on creating an inviting and comfortable atmosphere and that it can only be successful with an appropriate lighting strategy. With this project, we hope to inspire other design and development professionals to prioritize delivering high-quality, comfortable, and inviting environments in their projects through the effective integration of lighting solutions.

Sapa Rock N Ritual – A unique Theater in the middle of Vietnam Northern forest

Sapa Rock N Ritual is a theater project located on the Ham Rong mountain, in the northern region of Vietnam called Sapa, famous for its groundbreaking step rice field landscapes.

ScenoLight Atelier and its team of architects, scenographers, landscape and lighting designers, in collaboration with the show director and his artistic and technical team, has worked on this theater project for two years. Together we spent days on site to feel the atmosphere and learnt about the local traditions and materials that inspired the design and performance. One of the most sensitive aspects of our cooperative decision was the selection of theater location and direction, taking into account access constraints, view, climate, and beliefs. Our mutual thought leads us to consider the theater as a performance all by itself, providing a full experience focused on the four natural elements that created the legend of this magnetic site also known as the dragon head: rocks, air, water, and fire.

Back in our office, we carried out extensive research, combining traditional methods with a variety of parametric designs to generate multiple types of shapes that were meticulously installed on the natural topography. As a result, we came up with the concept of an open-air wooden structure connected to the rocks and floating in the landscape between the bamboo forests and the mountain’s peak. As a decorative but also structural element, the outline is covered by a marble string, inspired by the ethnic traditional textile patterns and jewelry.

We fully concentrated on the environment surrounding the theater, since the audience discovery experience begins at the lower level of the site’s path, which leads through the bamboo forest to the theater. The audience is then welcomed to enter inside the theater, which has an open-air lobby offering a spectacular panoramic view of the valley. After crossing the small footbridge over the landscape, the audience is invited to take their seats on the circus-style step benches arranged around the stage and facing an impressive rocks landscape. By night, the special lighting effect transforms it into a floating cloud between the mountain and the bamboo forest, highlighting the marbles, stone strings, and creating a magical landmark for the resort where it is installed.

The theater has 300 seats and an 80-square-meter stage, as well as a full set of lighting and sound equipment, and is covered by a tensile membrane roofing system and a curtain structure to enclose the space in the event of a blackout or for weather reasons. The backstage area, which includes a control room, is also accessible from both outside and inside the main volume. Every effort has been taken to create this theater as functional for the performers, technicians, and operation as possible even though the site and budget constraints are limitative.


Cyril Lamy, our Creative Director, was invited to a meaningful seminar with the participation of the domestic and international Design Community in the VMARK Vietnam Design Week 2022, organized by the Design Association of Ho Chi Minh City (VDAS). The event took place at the most luxurious venue – HCMC GEM Center with great success. 

At VMARK Vietnam Design Week, Cyril and other speakers who are passionate and outstanding in Architect and Design had an opportunity to attend and share personal perspectives on the topic “Creative for Life”. The event also generated exciting activities and connections between large domestic and international businesses.

VMARK Vietnam Design Week 2022 welcomed a massive number of Architecture and Design enthusiasts, including University students, lecturers, and large domestic and international corporations. All of the missions of Architects and Designers are to add value to not only their clients but also to our lives, despite a variety of difficulties and challenges. As a result, the event was organized to contribute and strengthen Vietnam’s distinct conceptual identity, with the goal of ensuring that Vietnamese Design is recognized worldwide and sustainably developed.

SLA is grateful for the opportunity to attend a seminar of VDAS, where we were able to share our valuable design and architecture knowledge with other partnerships. We are looking forward to other related events that will cover a wide range of amazing and appealing topics, particularly in Lighting Design, which is our area of expertise; therefore, we will be able to share our comprehensive understanding and inspiration with anyone involved in lighting design, as this is not universally acknowledged in Vietnam.

The term Media façade has been used more and more in today’s world, it’s not only a stylistic feature anymore but an icon for the architecture itself. From the flashing illuminated advertising, Media façade is on the way to conversion and turned into a vast advertising medium, basically for sending messages. But the term Media façade is getting further nowadays with a more profound purpose rather than an advertising medium.

Architainment Media Façade

Imagine any glimpse of a moment from humans can create a different effect on the Media façade. Technically speaking, any impulses from the surrounding area are transmitted into computer-aid graphics, thanks to the sensors. Hence, the content of the Media façade is driven by the visitors. Interactive media façade was the work of lighting designers, architects, engineers, mathematicians, and programmers. Once the night comes, the building is alive, the light show becomes the main attraction. Media façade, in general, can evoke diverse emotions, a message can be impactful delivered, and buildings can be distinct from city light pollution. All of those elements well-combined together into a new wave of lighting design art form – Architainment media façade. Briefly, Architainment is still sharing the same purpose with the Media façade – sending information but in a more subtle way. The Architainment façade is more similar to art installation, making the building iconic. As you can imagine the sharp line between media façade becomes blurry, thanks to technology and lighting designers.

Our Concept

SLA Designers has developed an interesting architainment façade concept for a building located in Ho Chi Minh city. Based on the architectural philosophy of the building, a contemporary Japanese concept, we generated many forms, shapes, and patterns for the façade lighting layout which was inspired by east-Asian daily objects and design language.

Lastly, we installed sensors in the main lobby to detect any vibration in the frequency of sound, talking, chit-chatting, or basic noises would be beautifully visualized via our lighting façade design. Eventually, the façade would feature a colorful sound wave, and anyone who appeared in the surrounding would feel the liveliness inside the building. That is likely to enhance the lighting design more profoundly and poetically. In addition, implementing volume light on the rooftop can create more connection between rooftop light and façade lighting.

Besides the primary purpose of artificial light as it has been using nowadays for functional and security purposes, lighting also serves social and aesthetic functions by influencing how cities are used and perceived.
The urban perception after sunset is an important part of its character and take also a crucial role in tourism attraction. But to reach a level of global approach, the lighting master plan has to deal with multiple actors, private and governmental, which requires certain regulations not only technical, but also sensitive and creative. This approach has to takes into consideration the city landscape as a four dimensions public areas, the architectural structures at different space, which are the urban layout, literally the roads and scale, and the time, from the set to rise of the sun.

As creative lighting designers, we aim to think our projects with this global thinking, from the context analysis we extract the personality of the site that should be tells by night through a proper illumination, responding to the functional request with creative interpretation. To develop such lighting master plan we are used to work by layers of light, independently from the urban functions, but from a plastique point a of view, following four main approach: horizontals, vertical, landmarks and scenarios. Horizontal lighting give us a vision of the use of space. The lighting has brought by masts, bollards and trees are according to the traffic level and importance of the axis. Vertical lighting brings contrast and legibility at bigger scale to the urban landscape, some façades located on axis are then chosen to be light up because they are located on important sightlines and allow us to highlight some main crossroads and important activity zones. Landmarks lightings brings story in the nightscape, by generating breaks in terms of intensity, colors, or other lit effects, and also to create events.

Of course all this different layers have to be harmonized and in accordance with public safety, urban services as well as concern for consumption. But this functional aspect of the lighting should be forgotten from the user point of view, because the night ambient in our city are part of our culture, and lighting has big responsibility in the night environment sustainability.

Ha Long Premier Village Project

For this new urban area, SLA designers has been missioned to light the full urban areas, landscape and facades. First thing we had to consider is the position of the site on the sea side, it is why we proposed a global graduate illumination installation from the main road to the coast line, in order to avoid light pollution and to enjoy the stars sky. We also overlapped several horizontal layers, according to the different architectural styles of each zones, but still with a common logic, as a way to keep a general feeling of guidance and landmark. In terms of façade lighting, we chose to highlight the main roads façade with a strong reinforcement a the main gate. But inside the urban area, we selected only some facades because of their position and the visitor point of view. The general idea is to not overload the lighting, to generate contrast and maintain a graduation in the general illumination till very low luminance on the sea coast.

SLA Designers has been operating in Vietnam for five years. As a young company in this country, we have been facing many different situations in the façade lighting field through local projects. The experience of realistic collisions, of knowledge, of demonstration in this market, makes us have some real thoughts that we are willing to share in this article for those who concern. 


Lighting for the façade gets the most community concern in lighting design field applications. The reason for this is that façade lighting has a heavy impact on the nightscapes that define cities’ identity as a symbol of their reputation and for an attractive touristic image.

Ben Thanh Market, a symbol of Saigon but not carefully designed in terms of facade lighting that creates an unprofessional look for the architecture

However, in some emerging markets like Vietnam, façade lighting is rarely handled by creative lighting designers, it is briefly designed by lighting solution providers who have to optimize their time for commercial reasons while answering the developers for outstanding “make-up” lighting.

We analyze the main reasons for that:

  • No urban lighting strategic plans
  • Over-bright designs requested by investors for standing-out reasons
  • No advice for minimizing coming from lighting solutions providers
  • LED dynamic technology becoming more affordable
  • Wrong thinking that hiring professional lighting designers will cost more

Results from these reasons are repetitive designs, uncontrolled use of colors, light pollution, and at worst a failed installation because of a lack of maintenance issues assumptions. From the city’s point of view, this combination of out-of-control lighting generates a messy vision of the city, while impacting the human and natural environment.

An example of direct facade lighting misleading to highlight or bring value to the architecture



Our mission is to work with alternative lighting brands to offer not only creative designs but also a reasonable budget. Also, we are the best solutions that suit those responsible for the project finalization. Therefore, from the original concept until the final setup, we ensure the coordination between all parties involved in the lighting studies and installation.

In addition, as creative people, our expertise and skills bring more valuable and durable results for façade lighting:

  • We take into account the project program and environment
  • We know how to integrate lighting into the architecture to enhance it
  • We create a unique design for each project, considering the branding identity, the type of building, etc…
  • We anticipate maintenance process and cost operation, as practical access and weather conditions
  • We advise on the perfect balance between design and budget, preferring to minimize the quantity than lower the quality


It is important to understand that a mindset change is necessary on façade lighting topics because, in the end, all parties would find its interest:

  • Firstly the investors because they will get a better result for the same budget
  • The lighting brands and suppliers because they will avoid spending unpaid time to provide solutions that have to be reviewed, updated, and coordinated.
  • We, as creative lighting designers because we can design projects that we are trained for many years to design.
  • And finally, the cities because they will get a step by step improvement of their nightscape environment.

As creative lighting designers, SLA Designers has also the mission to inform and explain these new fields and the continuous evolution of technology and its impact on our environment. It is why we are glad to meet future city makers, developers, and urban thinkers to present our vision and discuss the possible evolution and proper way to evolve the nightscape together.

Light always tells us unconsciously something, as an abstract language, with various cultural and historical varieties of interpretations. This essential language of the sun and fire has been manipulated from the origin of humanity through the arts of painting and sculpture, and deeply explored since the advent of artificial lighting by photography, cinema and performance arts. Artists know how to convey the dramatic power of the light to tell their story, to guide the interpretation of a scene, and to increase the meaning and emotions.

Prehistoric paintings used the shaking of firelight to simulate the animals’ movements, playing with shadows and overlapping images.
La Grotte Chauvet, about 30 000 years old, France

The term dramatic lighting to convey a meaning, mood, and as well as atmosphere, is an artistic affair when it comes to architectural or landscape lighting design.

At SLA designers we always start designing our projects from this point of view. As we believe in the power of creating emotions with light and also with architecture and landscape.
Dramatic lighting applied for architectural and landscape projects. This project has been thoroughly elaborated from photography and cinema references, following the architect’s surreal world. The techniques and equipment are also quite similar to the ones applied for a photo shoot or movie scene, by staging the position of each light, carefully choosing the color palette, and light direction.

Contrast and eye direction

Painting is one of the oldest mediums which uses dramatic lighting. Light and Shadow – Good and evil, chaos and control, controlling these two elements is one the most important tasks to achieve dramatic lighting. It is a so-called shading technique, to create volume and space, volume can be accentuated using back and side lighting, by highlighting prominent features, and leaving the rest in shadow.

Night Watch, Rembrandt – Lai restaurant, SLA designers, 2019

Rembrandt is a legendary painter from the Netherlands who is famous for creating extraordinary lighting techniques at that time in his art, like his masterpiece: A Night Watch. By using the dramatic lighting, the keystone, the part of the painting that holds everything in place are the dual figures of the captain and his lieutenant in the middle and the rest of the portrait moves away from them diagonally which makes them extremely highlighted. The dramatic lighting can single out two key figures and create an optical phenomenon called “Depth of field”. Ultimately, Rembrandt used this lighting method to point out to the viewer what detail to look at.

Enhancing mood and atmosphere

The scene from Suspiria (1977) has been fairly simply lit with one big heavily diffuse backlight and a piece of poly at the right to bounce the light back in – That it’s! Simple. But the cool touch is from the lighting on the eyes of the protagonist which holds the reflection from a 45-degree teleprompter, so no post, all done in camera. In contrast with the scenes from Suspiria (1977), the dramatic lighting sources are very complex, and the use of Technicolor is in harmony to create a surreal world that the protagonist is placed. But in total, however the simplicity and complexity, lit effects were used to enhance the mood and atmosphere.

Suspiria (1977) – Crazy House project by SLA Designers 2018

Color and emotion are bonding closely with each other, it is associated with the narrating and immersive experiences of the scene. To give the clue to the viewer or quickly or completely, getting them emotion the visitor to help them understand the story more involved with the scene or architecture. By choosing a color palette according to the theory of color and emotion, or using the gobo, the glowing light technique, we can reveal the characteristic area of the lighting design.

Spectacular and Storytelling

Lighting is a powerful material to produce spectacular effects; and as this ultimate encounter between show and architecture, lighting installation applied to the façade or interior turns the architecture for the visitors into an audience. The dramatic aspects of light are emphasized by a scenario, often completed by sound and music and other media, to tell a story, to tell its history, to immerse viewers into the creator’s perspective. This is the art of using the right angle, the art of fine-tuning intensity and colors, balancing between light and shadow, revealing characteristics, bringing movement to the light, adjusting the composition, enhancing the authenticity of the architecture, making uniqueness, and expanding the boundaries of the space. The art of the creative lighting designer combined with a scenography vision.

Lighting for hotels, boutique hotels and resorts is a major topic nowadays for the developers and operators in the Hospitality industry because it plays an important role that able to decide whether the guests’ experience and the atmosphere of the space positive.

It is also a primary subject for lighting designers as lighting applied to the hospitality gathers various constraint and requirements in a single project. Each area such as lobby, guestrooms, restaurants, spas, conference rooms, etc. requires its specific lighting set-up and equipment standard. To lighting designers, this is the challenge and the impulse to ensure that the practical management and maintenance of the operational team can provide the qualitative lighting environment for the guest – what we call Feeling of Wellness.


Light by nature has an invisible impact on our body and mind through multiple variations. Researches show that our eyes ‘cells respond differently to particular wavelengths of light and send the information to our brain to regulate our alertness and sleepiness levels.

Our first light source is the sun, which emits a spectrum of light with high blue wavelength content during daytime, telling the brain that it is daytime and signaling the body to be alert, while the yellow tones corresponding to sunset generate relaxation. This natural cycle of light is called a circadian rhythm, and from a lighting designer point of view, the goal is to match the natural environment with proper use of color temperature from artificial light, expressed in degree Kelvin, or more commonly named cold to warm light. Then, the flexibility of the lighting installation is also very important to be accurate with the actual needs of the guests, from the public areas where lighting has to be adapted to the day and night time, to the guest rooms where light has to be easily adjusted by the guest for his personal mood.


Lighting designers are always looking for different ways to get the comfort and legibility of space, while generating a specific atmosphere and an aesthetic combination with the interior architecture.

Our first analysis and discussion are about natural light, which is necessary to be controlled for some specific areas. Then the more direct aspect extracted from the circadian rhythm is the choice of the color temperature, mostly in the warm range, combined with cold white for predefined tasks areas, or for some entire space that required to be flexible in terms of function, as ballrooms. Light manufacturers also have this concern about the color temperature and the specific requirements for flexibility, so they developed a dedicated range of products called tunable white. Once these technical aspects defined, all the art of lighting design is about combining the decorative light sources with indirect, task lights and focal sources, in order to generate a full lighting environment form the main entrance to the guestrooms that keep a coherent atmosphere signature.

Hotel category, budget, operation guideline and maintenance constraints, all these aspects are particular to each project. Hotel brands are also looking for innovation and up-gradation of their own standard. Wellness through lighting for hospitality requires experience and attentive studies. Therefore, lighting designers are at this position to collaborate with the operator and other consultants to involve in the design as well as propose the best solution that should be able to answer globally to these various goals.
