FWIW - Being the hard headed skeptic I am, I went ahead and bought the Lutron IR dimmer. It did not work with my LED's, they are Utilitech brand from Lowe's. A buddy of mine just replaced his recessed incandescent lights with Home Depot LED's, so I let him try the dimmer. It works on those! He also has the Harmony 650 and it controls them perfectly. I still find it hard to believe that no one has an IR dimmer that is made to control LED's.
