Possible lighting options

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

UL Type C TLED and Retrofit Kits• Works within the existing housing• Dimming drivers• Requires modifications of existing fixture by an
electrician• Plug and play options exist
Dedicated‐LED fixture• Dimming drivers near standard• Many contain integral sensors• Wireless communication• Plug and play more than any other option
