LeanLight is proud to announce our latest product addition - Sylvania DUALescent LED tubes. The Sylvania DUALescent LED tubes are hybrid LED tubes that work with or without a ballast. The Type A+B LED tubes simply snap-in as a directly replacement of linear fluorescent lamps. Once the fluorescent ballast fails, simply bypass the ballast wiring the LED tube directly to the input power using a double-end power configuration. Shop for Sylvania LED12T8\/L48\/FG\/841\/AB, Sylvania LED12T8\/L48\/FG\/850\/AB or all LED tubes at LeanLight.
