Questions
Why does my LED light flicker or not dim fully with a new dimmer?
Usually the bulb and dimmer are poorly matched or the load is below the dimmer's minimum. Many LED-rated dimmers have a low-end trim adjustment, and switching to a bulb on the maker's compatibility list typically fixes it.
Do I need a 3-way dimmer at both ends?
No. Typically you install one 3-way-capable dimmer at one location and a regular 3-way switch or the brand's matching companion at the other. Follow the specific dimmer's wiring instructions.
