What Kind of Dimmer Is Needed for LED Lights?

LED lighting needs an LED-compatible dimmer to work properly — many older dimmer types simply aren't compatible. We'd always advise upgrading your dimmer at the same time as your lighting.

Why do LED lights need a specific dimmer?

Older dimmers were designed for the electrical characteristics of incandescent or halogen bulbs. LED bulbs behave differently, and using an incompatible dimmer with LED lighting commonly causes flickering, buzzing, or a limited dimming range. An LED-compatible dimmer is designed to work correctly with the lower power draw and different electrical profile of LED bulbs.

Which dimmer would you recommend?

We'd always recommend Varilight V-Pro dimmers. They're the leading LED dimmer on the market, and for good reason — they work with more LED lamps than most, if not all, other manufacturers, and offer excellent reliability.
