A Tri-Colour CCT LED Downlight (Correlated Colour Temperature) is a type of LED downlight that lets you switch between three colour temperature settings:
Warm White (typically 3000K)
Cool White (typically 4000K)
Daylight (typically 6000K)
This makes Tri-Colour downlights a versatile option, allowing you to choose the lighting tone that best suits your room, décor, or mood.
How do I switch between different colour temperatures on a Tri-Colour LED Downlight?
Most Tri-Colour CCT LED Downlights can be switched between colour temperatures in one of two ways:
A built-in switch on the rear of the fitting (commonly used during installation), or
A programmable power on/off switching sequence (cycling through colour modes using the wall switch)
This gives you flexibility to adjust the lighting warmth depending on the space—whether you want a cosy glow or a brighter, more task-focused light.
Are Tri-Colour LED Downlights dimmable?
Some Tri-Colour LED Downlights are dimmable, but this depends on the model.
If dimming is important, always check the product description to confirm:
the downlight is dimmable, and
it is compatible with the correct dimmer type
Using an incompatible dimmer may cause flickering, buzzing, or reduced dimming performance.
Are Tri-Colour LED Downlights energy-efficient?
Yes — Tri-Colour LED Downlights are considered highly energy-efficient because they use LED technology, which:
consumes significantly less power than older lighting types
produces less wasted heat
lasts much longer, reducing replacement frequency
This means they’re a smart choice for reducing electricity costs while still providing bright, reliable lighting.
