Over the years of working with business leaders, I have realized that designing the chairman office is not just about arranging luxurious furniture or choosing expensive materials. It is the art of creating a space that reflects the vision, style and class of the leader. And lighting – especially LED lights with a color rendering index CRI > 90. is the decisive factor that makes every detail most vivid and realistic. From the perspective of a design expert from Proce, I would like to share the secret that I have learned after many years of working: Why is high CRI the “light signature” for classy leadership spaces? Let’s find the answer through the article below!
1. What is CRI? And why is it important in designing the chairman office
As a design expert at Proce, after many years working in the field of luxury interior design. Especially the president’s room. I realized that light is not only a technical factor. But also a “language” that expresses the class and emotion of the space. One of the most important factors when it comes to quality light is CRI – Color Rendering Index. Simply put, the higher the CRI, the more realistic the color of the object under that light. The closer to the real color when viewed under natural sunlight. This seems small, but it deeply affects the way we perceive space.
For example, with a CRI below 80, colors become dull and distorted. Human skin can look pale or gray, and wood or leather materials lose their soul and depth. Meanwhile, light sources with a CRI above 90 bring amazing vibrancy and fidelity. Walnut wood surfaces appear with clear grain. Real leather has a natural shine, and marble exudes a sophisticated elegance.
In special spaces such as the president’s office or high-level meeting room. Where every interior detail is carefully selected to express style and status. Ensuring light with a high CRI index not only helps to honor the value of the material. But also contributes to shaping the overall emotions and experiences. Because the right light does not simply illuminate objects. But also breathes life into the space, telling the story of emotions and class.

2. The impact of high CRI on the chairman office space
Enhancing the aesthetics of materials and furniture in the designing the chairman office
In high-end design, each material, from walnut wood, genuine leather to copper-plated metal… has its own “aesthetic language”. However, for these materials to truly shine, light with a CRI index of over 90 is an indispensable factor. With many years of experience designing leadership spaces, I have found that standard lighting not only helps to highlight the natural wood grain, the shine of metal or the warmth of leather. But also helps architects control the interior color palette exactly as the original design.
When CRI is low, the light spectrum is distorted, causing the material color to become “off-tone”. The precious wood panel can become dull or the luxurious Italian leather loses its inherent depth. That is why, in projects of the president’s office or high-level executive space. I always consider CRI >90 as the “gold standard”. Because light is the true “preserver” of the aesthetic value of the material.
Create emotion and style for the leader
Light not only affects objects, but also has a strong impact on human emotions, demeanor and energy. With high CRI, the light source faithfully reproduces skin tones. Helps the leader’s face stay fresh, natural and full of confidence. Many studies in the psychology of light have shown that true, warm light will help reduce visual stress. At the same time, it brings a sense of concentration, relaxation and subtle power. In the president’s room, this is especially important. Because light both supports functionality and creates leadership temperament and character.
When high CRI light reflects on luxurious materials. It evokes a feeling of warmth but full of majesty. A balance that feng shui calls “bright – soft mutual support”. Bright but not dazzling, strong but not cold. Thanks to that, the leader can fully feel the harmony between power and relaxation. So that every moment in that space carries the most positive and natural energy.
Supporting brand image and partner experience
In a high-level leadership environment. Lighting is not only for the people sitting in the room. But also for those who enter. A light source with a CRI of over 90 will help every detail, from logo color, gifts to employee uniforms… to be shown according to brand identity standards. With practical experience in many reception room design projects for large corporations. I have witnessed many cases where brand colors are “misaligned” under low CRI lights. Red tones become orange, blue tones turn gray. Making the corporate image lose its sophistication and consistency.
On the contrary, when true light is applied. The space becomes uniform, luxurious and has brand depth. Moreover, standard light also enhances the partner experience. Because true light is a manifestation of professionalism and respect. That is also the reason why in Proce’s design, we always consider high CRI as a technical standard. And a part of brand identity. Contributing to telling the success story of each business.

3. How to choose LED lights with CRI > 90 according to the standard for designing the chairman office
In lighting design for the president’s office. Choosing LEDs with CRI above 90 is not simply following technical specifications. It is a process of fine-tuning based on experience, feeling and deep understanding of materials, space and people. After many years working with major lighting brands in the world. I realized that the decisive factor lies in the fidelity of information and suitability for use. Not just the numbers on the catalog. Therefore, when choosing a lamp, the first thing I recommend is to check the actual CRI parameters from the manufacturer. Prioritize brands with reputable international certifications. Such as LM-80, TM-30 or energy star.
Prefer to use CRI > 95 for main area
For key spaces such as meeting rooms, desks or executive reception areas. Choosing a light source with a CRI index ≥95 is considered the optimal standard. This CRI level helps colors display faithfully and clearly. Allows users to easily perceive the material and hue of objects. At the same time, it reflects emotions and facial expressions naturally and vividly. Besides the CRI index, the color temperature of the light is also a key factor in shaping the emotions and style of the space.
Specifically, the light has a temperature range of 2700-3000K with a warm, soft yellow color. They are often preferred in luxurious spaces such as the president’s room. Where it is necessary to create a friendly, sophisticated but still powerful and classy feeling. This type of light not only brings comfort to the eyes. But also contributes to highlighting the depth of materials such as wood, leather or high-class metal. On the contrary, neutral white light of about 4000K is suitable for work areas or meeting rooms. Places that require alertness, concentration and high visual efficiency.
The delicate blend of high CRI and precisely selected color temperature is the key to evenly spreading light throughout the space. At the same time, it shapes the style, emotions and class of the leader.
An interesting note that many people still misunderstand
High CRI does not mean high power consumption. Thanks to modern LED technology, especially new generation LED chips. Light with CRI >90 still achieves high lighting efficiency, long life and energy saving. At Proce, we always consider the choice of high CRI light as an art of balancing science and emotion. Where each light source not only serves function. But also contributes to shaping the aesthetic identity and spirit of a classy space.

Conclude
After many years of working, I always believe that a perfect president’s office design is not just about form. But about the way the light tells the story of the leader. The CRI index > 90 is not simply a technical parameter. It is the boundary between a luxurious space and a space with a soul. As a design expert of Proce, I always choose standard lighting as a sophisticated companion. So that every interior detail, every architectural line reflects its true value. Because standard lighting not only illuminates. But also honors people in the right way. That is the philosophy that I have persistently pursued throughout my career.
