As others have said, CFL and LED probably won't work (at least as expected). It has no connection for neutral lead and must pass sone amount of current through the load (which will result in most LEDs staying on at a low level). Don't understand why nobody offers this in a version that takes a neutral when available, which would greatly improve compatibility with non incandescant bloads.
