Dimmer Switch for LED Light Fixture

How to Wire a Dimmer Switch for LED Lighting

Light Fixture Components and Dimmer Switches

Electrical Question: I am trying to identify a problem. I am running a series of 3 LED recessed lights 4 watts each (I know how it’s done) with a dimmer switch. After wiring, the lights flashed quickly and continuously. I tried a regular single pole switch and everything worked. I tried a different dimmer switch, but now the breaker keeps tripping. I double checked the wiring in the switch box. All is good. Will a dimmer work? Wiring it is easy enough (single pole). I thought there might be a short at the light connections, but everything worked with the single pole switch, so ruled that out. Any suggestions?

    Hi David,
    Using a dummy load is an interesting idea, but keep in mind that the load will create heat so it would have to be installed with that in mind. I would first make sure the dimmer is not sized too large and use the Trim Adjustment that will allow further range of operation. Most dimmer switches have a trim adjustment which is located on the top or bottom of the dimmer switch and the adjustment can only be made before the dimmer is installed into the switch box, and the adjustment is made using a small screw driver. There are a few other dimmers that have adjustments that are accessible behind the front cover plate.

    My led lights flash when I dim them, but have found if I use one 100 watt incandescent bulb on the “string ” of 12 watt LED bulbs they dim fine. Can I use a dummy load to simulate the incandescent bulb? What would I use?
