Legrand
Legrand's Dimmer Compatibility Chart can help you find the right dimmer for use with incandescent, halogen, fluorescent, LED, CFL, MLV, ELV bulbs. First, find your bulb type on the chart. If you are not sure what bulb you have, then select a Tru-Universal option that works with ANY bulb.
Lutron
Lutron only recommends dimmable CFL and LED bulbs that they have tested (per UL) and deemed compatible with their dimmers.
Please use Lutron's LED Compatibility Tool to ensure you're using a bulb that is approved for their dimmer.
If the bulb you are using does not appear on the approved list, please contact the LED manufacturer for a dimmer recommendation.
Please note: Bulb variations in lamp design and construction affect performance. Bulb manufacturers can modify their bulbs at any time, without notice to Lutron. This prevents Lutron from ensuring ongoing compatibility. For up-to-date specifications, performance, and/or any related recall information about the bulb, please visit the bulb manufacturer's website.
