What the AI looks for in Dimmer Switches
- LED compatibility
- Use a dimmer rated for LED/CFL loads, and stay within its LED wattage rating, which is lower than its incandescent rating. Older incandescent dimmers cause flicker, buzzing and dropout with LEDs.
- Low-end trim
- Choose a dimmer with an adjustable low-end trim. The trim adjustment is the main tool for fixing LED flicker at low levels.
- Ganging derating
- Reduce the load capacity per the manufacturer's chart when several dimmers share a box and side fins are broken off. Removing the fins reduces heat dissipation.
- Load type
- Use fan-speed controls for ceiling fans and dimmers rated for magnetic or electronic low-voltage transformers where applicable. Standard dimmers can damage fan motors and some transformers.
- Bulb dimmability
- Install only bulbs marked dimmable. Non-dimmable LEDs flicker or fail regardless of the dimmer.
Brands that matter
- Lutron: Best LED compatibility testing and trim adjustments.
- Leviton: Good alternative with a wide style range.
- Legrand: Design-focused options in the radiant and adorne lines.
What to avoid
- Incandescent-only dimmers used with LED bulbs.
- Mixing different LED bulb brands on one dimmer.
- Putting a standard dimmer on a ceiling fan.
Questions
Why do my LEDs flicker on a new dimmer?
The low-end setting is usually too low for the bulbs; raise the dimmer's low-end trim or switch to bulbs on the manufacturer's compatibility list.
