I have done some testing with a 2467D Hardware 2.2 and some dimmable LED Bulbs. They worked fine on the SwitchLinc Dimmer. Philips EnudraLED 12.5 watt. Both hardware versions. EcoSmart 9 Watt. Sylvania Ultra LED 8 Watt.
I have seen users with LED fixtures using them. You may want to look at the fixtures specifications. Some say only so many on a dimmer due to power surges.
