LED Dimmer

Most LED fixtures take far less than 65-watts. You might want to double-check the label on the fixture. Most show a wattage equivalency for incandescent lamps they would replace, and a second actual wattage for the LED replacement. Most of the 60-watt equivalent lamps I've used as replacements only take 11-13-watts, but give off as much light (in lumens) as an old 60-watt incandescent. We've got six LED replacement fixtures in our garage and all six together only take 66-watts.

To clarify, the 150W rating of CFL/LED is based off of the energy actually used for the CFL or LED bulb, and not the wattage equivalent. It is very rare for an LED to equal 65W as they are normally 8W for example and equivalent to a 65W incandescent in terms of how much light it outputs. In this example, the 8W rating of the bulb is what you would use and you would be ok to place four of them on a single dimmer.
