can u use a dimmer on kichler xenon under cabinet light

trinity_2010June 30, 2011

these are line voltage, can u use a dimmer on them? the have a two position switch on the lights themselves but i prefer to use wall dimmer and leave them on high

I don't know about "u" but "you" certainly can.

What does the manufacturer say?

The biggest problem is if the lights contain low voltage bulbs they may have a power supply that is NOT compatible with certain types of dimmers (or any dimmers).

The input voltage is NOT the only thing you need to know.

ok i called the kichler and they said yes but it needs to be 'electronic' dimmer....i assume this is not your everyday dimmer?

You need a dimmer that says it can be used with fluorescents or low voltage lights. Some of the cheaper dimmers get screwed up with trying to find the zero crossing on a non-resistive load.

"Some of the cheaper dimmers get screwed up with trying to find the zero crossing on a non-resistive load."

Worse than that, the chopping of the leading edge of the voltage waveform causes a lot of high frequency noise that can destroy transformers and power supplies not especially designed to cope.

Shutting off on the falling edge before a zero crossing is not nearly as bad, but takes a different part than a Thyristor used in common incandescent dimmers.
