Q: What does tunable mean in lighting?

A: Tunable white light illumination technology is defined as the ability to control the color temperature output of a light source. It is also known as variable white light, dark-to-white light, mixed white light, or other manufacturers’ customized temperature lighting.

Q: Is Tunable the same as Dimmable?

A: While both tunable and dimmable lighting systems provide control over the intensity of light output, they are not the same. dimmable lights provide control over brightness, tunable lights offer the additional capability to adjust both brightness and color temperature. The choice between dimmable and tunable lighting depends on the specific requirements and preferences of a particular lighting application

Q: What is tunable white meaning?

A: Tunable white refers to a lighting technology that allows users to adjust the color temperature of white light emitted by a light fixture. This adjustment can range from warm white (around 2700K) to cool white (up to 6500K or higher). Tunable white lighting allows for dynamic adjustments to suit various activities, moods, and times of day, providing a high degree of flexibility and customization.
