Why can't I dim my LED?

If an LED light cannot be dimmed, it often causes confusion. In many cases, however, the cause lies not with the light itself, but with the combination of dimmer, power supply, and bulb.

Not every LED is dimmable, and not every dimmer is suitable for LED lights.

Possible causes

Lamp not dimmable The built-in LED is not designed for dimming.
Incorrect dimmer The existing dimmer is not suitable for LED lights.
Minimum load not reached The connected power is too low for the dimmer.
Transformer not dimmable A transformer in front of the unit does not support dimming.
Combination not compatible The light fixture, dimmer, and ballast are not technically compatible.

Dimming always involves the interplay of several components. If one of them malfunctions, the light cannot be dimmed, or only to a limited extent.

A professional assessment helps to narrow down the cause and find the appropriate solution.
