LED Circline Lamps

LED circline lamps replace FC8T9 (8 inch) and FC12T9 (12 inch) fluorescent circlines, which can no longer be sold in California. Match the diameter first, then the install type. Type A lamps plug into the existing ballast with the same 4-pin G10q connector. Ballast bypass (BP) lamps wire to line voltage, so an electrician should do the conversion, and then there is no ballast left to fail. Text a photo of the old lamp or the fixture's ballast label to 949-589-3020.
