FAQ

Can I change the color temperature after the downlight is installed?

The CCT is selected via a side slide switch before installation. The chosen setting stays locked until manually adjusted — it cannot be changed via the wall switch.

Which color temperature is best for a home office?

4000K neutral white for standard working hours provides balanced clarity without over-stimulation. 6500K cool white is recommended for high-demand focus sessions or late-evening work.

Does the color temperature affect sleep quality?

Yes. Warm 3000K light in the evening reduces blue-light exposure, supporting natural melatonin production and a smoother wind-down toward sleep.

Is this downlight dimmable?

Yes. It dims from 10% to 100% with a compatible LED dimmer switch, allowing full brightness control across all three CCT settings.

Can this be used in a bathroom?

Yes. The IP44 waterproof rating makes it safe above showers, vanity areas and in humid bathroom ceilings across all three CCT modes.
