Electrical — FAQ
Do I need special bulbs for LED dimmer switches?
Yes. Use dimmable LEDs clearly marked 'dimmable.' Non-dimmable LEDs will flicker, buzz, or fail prematurely. We recommend Philips Warm Glow or Cree bulbs for best performance with Lutron and Leviton dimmers. Avoid cheap off-brand LEDs—they often lack proper driver circuits.
Can I install a dimmer switch myself?
If you can wire a standard switch, you can install a dimmer. Turn off the breaker (not just the switch), verify power is dead with a tester, then connect wires to matching terminals. No neutral needed for basic dimmers. If your box has aluminum wiring or is overcrowded, hire an electrician.
Why does my LED bulb flicker on a dimmer switch?
Flicker indicates incompatible bulb, insufficient minimum load, or poor-quality dimmer. First, verify bulbs are dimmable-rated. Next, ensure total wattage exceeds the dimmer's minimum (usually 10-25W). If problems persist, upgrade to a Lutron LED+ or Leviton Decora with anti-flicker technology.
What's the difference between single-pole and 3-way dimmers?
Single-pole controls one light from one switch location. 3-way dimmers work with a second switch controlling the same light (hallways, stairs). Most quality dimmers support both. For multi-location dimming, you need one dimmer plus compatible remote switches—standard 3-way toggles won't work.
How many LED bulbs can one dimmer switch control?
Divide the dimmer's LED wattage rating by each bulb's wattage. A 150W dimmer handles eighteen 8W bulbs. Never exceed the maximum rating. For large lighting groups (20+ bulbs), use Leviton's 300W DSL06 or install multiple dimmers on separate circuits to avoid overloading.
Are smart dimmers better than traditional dimmers?
Smart dimmers offer app control and scheduling but cost 2-3x more and require a neutral wire. Traditional dimmers like the Lutron Diva provide superior tactile control and reliability for basic needs. Choose smart only if you need remote access or voice control integration.
