Not all dimmer switches are compatible with all types of bulbs. Compatibility depends on both the dimmer and the bulb type:
- Incandescent and Halogen Bulbs: Generally compatible with most dimmer switches.
- LED Bulbs: Require dimmer switches specifically designed for LEDs.
- Compact Fluorescent Lamps (CFLs): Not all are dimmable; those that are require compatible dimmer switches.
- Smart Bulbs: Often have built-in dimming capabilities controlled via apps, and may not need traditional dimmer switches.
