Tunable White LED Strips for Circadian Lighting
For circadian and Human-Centric Lighting projects, a Tunable White LED strip should be evaluated by more than its CCT range.
Yuji Lux SunWave™ Dynamic White
Our primary Tunable White solution for daylight-oriented and circadian lighting applications. It combines a 2700–6500K tuning range with high color fidelity and full-spectrum spectral design for architectural linear lighting.

SunWave changes more than the visual appearance of white light. As the system moves through the tuning range, the spectral balance changes while maintaining high color quality.
SunWave™ spectral transition — dynamic SPD and color-quality characteristics across the daily cycle.
Tunable White Is Not Automatically Circadian Lighting
Changing from warm white to cool white does not by itself create a circadian lighting system. Circadian performance depends on the complete exposure:
Spectrum × Intensity × Timing × Spatial Distribution × Daylight × Controls
Two Tunable White systems with the same CCT range can have different spectral power distributions and different melanopic performance. For professional circadian projects, evaluate:
- SPD at representative tuning points
- melanopic performance
- vertical illumination at the eye
- CCT and Duv across the tuning range
- CRI, R9, and TM-30
- dimming and control behavior
- daylight contribution
Why SunWave Is Different from Conventional Tunable White
Many Tunable White products are designed primarily to change the visual appearance of white light. SunWave is designed around spectral quality as well. Its warm and cool channels are engineered to provide high-fidelity white light across the usable tuning range, making it especially relevant for projects that combine:
- dynamic white light
- high color fidelity
- daylight-oriented spectra
- circadian design strategies
- architectural linear integration
Daytime and Evening Light Need Different Strategies
Tunable White is especially useful for daytime and transitional lighting, but evening circadian design may require a different spectral approach. For projects where very low melanopic exposure is important in the evening, Yuji Lux also offers Dim-to-FlameWarm™, which transitions from 3000K to approximately 1250K and reaches an M/P ratio of approximately 0.099 at its warmest operating point.

Yuji Lux can integrate Tunable White strips into complete architectural linear systems including:
- aluminum profiles
- diffusers
- drivers
- controls
- project-specific assembly
- spectral and optical verification
Linear lighting is especially useful for circadian applications because coves, walls, ceilings, and other large luminous surfaces can help deliver light into the vertical field of view rather than concentrating illumination only on horizontal workplanes.

What is the best Tunable White LED strip for circadian lighting?
The right product depends on the project, but the key criteria are spectral performance, melanopic performance, color quality, output, chromaticity stability, and control compatibility — not CCT range alone. Yuji Lux SunWave™ is designed for high-fidelity, daylight-oriented Tunable White applications and can be integrated into professional circadian lighting strategies.
Is Tunable White the same as circadian lighting?
No. Tunable White is a technology that changes the white-light appearance of a source. Circadian lighting is a design strategy that also considers spectrum, intensity, timing, duration, spatial distribution, daylight, controls, and the light reaching the eye.
What CCT range is useful for circadian lighting?
A wide CCT range provides design flexibility, but CCT alone does not define circadian performance. The SPD and actual exposure at the eye matter more.
Does a circadian LED strip need spectral data?
For professional circadian design, SPD and relevant melanopic data are highly valuable because CCT and CRI alone cannot describe the non-visual spectral characteristics of the light.
Planning a Circadian Lighting Project?
Yuji Lux works with architects, lighting designers, integrators, and manufacturers to develop complete linear lighting systems for Human-Centric and circadian applications.
