Maxlite U11.5T8EX235DR2L11.5 11.5W T8 2-Ft Led (Ul-C) 3500K/4000K/5000K (2 Lamps), External Driver U-Bend 105058

PRODUCT DESCRIPTION: UL Type C LED U-Bend Lamps are the most energy- efficient, reliable and dimmable solution for replacing fluorescent tubes in T8 U-bend troffers. Designed to provide uniform illumination from end-to-end, the lamps are powered by a matching external driver for 1- or 2-lamp luminaires. To install the lamps, the fluorescent ballast is removed from the fixture and the driver is connected to the sockets instead of the mains voltage, providing optimal long-term performance, safety and reliability. The lamps may be paired with an emergency battery back-up unit (sold separately) that provides 90 minutes of power to keep lamps illuminated during power failures.
