What the AI looks for in Plug-In Dimmers

Bulb type compatibility
The dimmer must be rated for LED/CFL, and the bulbs themselves must be marked dimmable. Non-dimmable LEDs and dimmers made only for incandescent bulbs cause flicker, buzzing and early failure.
Wattage rating by bulb type
Stay within the separate LED and incandescent ratings, which are lower for LED. Each rating reflects what that load type does to the dimmer.
Low-end trim
Prefer dimmers that let you adjust the lowest dim level. Trim prevents LEDs from flickering or dropping out at the bottom of the range.
Load type
Use only for lamps. Never use for motors, fans, appliances or receptacles feeding other devices. Lamp dimmers are not designed for inductive or appliance loads.

Brands that matter

  • Lutron: The dimming specialist; Caseta for smart use, Credenza for basic use.
  • Leviton: Plug-in dimmers, including smart versions.
  • GE / Jasco: Wide range of plug-in lighting controls, including Z-Wave and Zigbee models.

What to avoid

  • Incandescent-only dimmers used with LED bulbs.
  • Using a plug-in dimmer on anything other than a lamp.
  • Wi-Fi smart plugs that claim to dim but only switch power.

Questions

Why does my LED lamp flicker on a dimmer?

The bulb is either non-dimmable or a poor match for the dimmer. Use bulbs marked dimmable, and set the low-end trim if the dimmer has it.
