UL Type A TLED• Works off existing ballast• Most existing ballasts are not dimming• Few manufacturers make dimming UL Type A TLED• Products being developed for after market dimming• Limits future options• What happens when ballast fails?

UL Type B TLED• Independent of ballast• Requires an electrician to disconnect and ballast and 

modify existing fixture• Requires wiring or wireless control signals• Must interface with a control device
