Hello, Does this dimmer module has the ability to dim LED bulbs

Asked by: Marlon King
Hi Marlon, The Universal Dimming Modules are designed for 120-277VAC (UDM08-EM) and 120VAC only (UDM08-EM-II) electrical systems. Both versions provide exceptional support of low and high-wattage LED and CFL lighting loads between 2-1200W@120VAC. UDM08-EM also supports these loads between 5-2770W@277VAC.
