Sunttro
Dynamic, natural light control empowering designers with full-spectrum indoor LED solutions
SUNTTRO: Intelligent Lighting
for Well-Being
SUNTTRO is an intelligent lighting control system co-developed by ULIGHT and BTHL. Born in 2019 and continuously evolving, SUNTTRO seamlessly integrates light with the environment, using illumination to promote well-being.
Unlike traditional lighting solutions, we do not provide complete fixtures—instead, we empower lighting designers with cutting-edge technology. SUNTTRO is a versatile system compatible with a wide range of indoor LED luminaires, recreating dynamic natural light that mimics the full spectrum of daylight variations—from the soft glow of dawn to the fading hues of dusk.
Cover 1600-12000K CCT
This human-centric lighting system,Compared with traditional standards 2700-6500K CCT, the color gamut coverage can actually be expanded by 13.68 times.
DUV shows how red or green tones shift within the same light temperature
Understanding Color Temperature and Chromaticity
Color temperature refers to the color of light, whether it is warm or cool. Chromaticity (DUV), on the other hand, indicates the degree of redness or greenness within the same color temperature. If the DUV is negative, objects will appear reddish. If the DUV is positive, objects will appear greenish
Our Solutions
Exclusive algorithm technology
Understanding 3000K CCT Variations. Precisely replicating both outdoor and indoor daylight as an exact copy of sunlight.
Duv tunable
Duv describes the distance of a light's chromaticity point from the black curve. With Duv adjustability, a single CCT can have multiple variants, offering more diverse lighting effects.
Customizable spectrum
For example, blue light can feature dual peaks, making the spectrum more continuous,closely resembling natural light. It reduces harmful blue light in the 440nm to 460nm range while supplementing beneficial sky blue light at 480nm, along with saturated red light, effectively minimizing the hazards of blue light and eye strain.
CRI >90 for all CCT; up to CRI >98
Colors appear more vivid and natural, ensuring high-quality lighting for daily needs. while remaining compatible with environmental lighting requirements.
A product designed for track lighting
Ideal as a light source for track lights, effectively enhancing visual perception for a more vibrant and comfortable experience.
