Install Dimmer Switches
Why It Matters
Dimmer switches reduce energy consumption by up to 25% and extend bulb life by reducing operating temperature.
Quick Guide
- 1
Gather your tools and materials
You'll need: Screwdriver, Voltage tester, Wire strippers. Materials required: Dimmer switch compatible with your bulb type.
- 2
Perform the install dimmer switches
Replace standard light switches with dimmer switches to control lighting levels and save energy. Safety note: Turn off breaker and verify power is off.
- 3
Verify and clean up
Check that the work was completed correctly and clean up your workspace. If if switch has unusual wiring configuration, consider calling a professional.

Community Tips
Dimmer switches are incompatible with most LED bulbs manufactured before 2015 and many CFL bulbs; verify compatibility before purchasing, as installing a standard dimmer on non-dimmable LEDs will cause flickering or premature bulb failure. The Lutron Caseta Smart Dimmer ($25-35) eliminates this guesswork by working reliably with 99% of modern bulb types.
Turn off power at the breaker and use a voltage tester on both the hot and neutral wires to confirm the circuit is dead—this two-step verification catches the occasional mislabeled breaker that causes preventable electrical shocks. Klein Tools Non-Contact Voltage Tester ($12-18) provides instant confirmation without direct wire contact.
Dimmer switches require a neutral wire in the wall box to function; older homes wired before 1980 often lack this wire, making installation impossible without running new cable through walls. Leviton Decora Smart Dimmer ($30-45) works on three-way switches common in hallways, but always confirm neutral wire presence during the initial inspection to avoid purchasing incompatible equipment. ---
