Dimmer Options. The easiest way to put an LED light bulb on a dimmer circuit is to use a bulb that's compatible with standard (incandescent) dimmers. Start with one bulb and see how well it works on your dimmer; you may decide to upgrade the dimmer switch and/or the bulb.Another option is to replace your old dimmer switch with an LED-compatible dimmer.y contrast, many LED bulbs won't work with standard dimmers—the kind you most likely have in your house. Also, even dimmer-compatible LED lighting typically can't be dimmed as low as incandescent and may turn off completely before the dimmer is at its lowest setting.
