Types of Dimmers
Slide Dimmer
Classic style with slider for brightness. Often has small on/off switch. Most affordable option.
Rocker/Paddle Dimmer
Tap to turn on/off, hold to dim. Clean modern look. Most popular choice for bedrooms.
Smart Dimmer
Control from phone or voice. Schedule wake-up routines. Higher cost but most versatile. Requires neutral wire.
Plug-In Dimmer
For lamps without built-in dimming. Plugs between lamp and outlet. No wiring required.
Before You Start
Safety First:
- • Turn off power at breaker - not just the switch. Verify with voltage tester.
- • Take a photo of existing wiring before disconnecting anything
- • Check bulb compatibility: LED bulbs need LED-compatible dimmers
- • Check wattage rating: Dimmer must handle total wattage of all bulbs on circuit
- • Hire an electrician if you have aluminum wiring or are uncomfortable with electrical work
Installation Steps
Turn off power and verify
Flip breaker off. Use non-contact voltage tester to confirm power is off at switch.
Remove old switch
Remove faceplate and unscrew switch from box. Pull out and note wire positions.
Connect dimmer wires
Match wire colors per instructions. Typically: black to black (hot), white to white (neutral), green to ground.
Secure and test
Push wires into box, screw in dimmer, attach faceplate. Turn on breaker and test all levels.
LED Compatibility
- • Not all LEDs are dimmable: Check package before buying
- • Use LED/CFL-rated dimmers: Standard dimmers can cause flickering
- • Minimum load matters: Some dimmers need minimum wattage to work properly
- • Stick to one bulb brand: Mixing brands can cause inconsistent dimming
Pro Tips
- •Consider smart dimmers: Lutron Caseta and Leviton work without a neutral wire in most older homes.
- •Preset levels: Some dimmers remember your preferred brightness level when turned on.
- •3-way switches: Need special 3-way dimmers if light is controlled from two locations.
- •Match your decor: Get dimmers that match your other switches and outlets for a cohesive look.
