The Topaz 40 Watt Emergency Driver Battery Back-Up Kit (Model F-LUHB/EMKIT, Order Code T72728) is engineered to keep your high bay lighting operational when the power goes out. Drawing just 8.5 watts of input power, this kit delivers a full 40 watts of output at 5,200 fixture lumens (130 LPW), ensuring your facility stays safely illuminated for a full 90 minutes of emergency run time — meeting both NFPA 101 and NFPA 70 safety standards.

Powered by a long-lasting LiFePO4 battery (12.4V, 6,600mAh / 84.48Wh) with approximately 1,000 typical life cycles, this kit accepts a wide input voltage range of 120–277V and recharges fully within 24 hours. Its IP65-rated, color-coated sheet metal housing withstands ambient operating temperatures from 32°F to 122°F, making it well-suited for demanding commercial and industrial environments.

Designed for compatibility with round high bay fixtures rated up to 300W, the kit integrates seamlessly via 0-10V dimming connection and includes a remote control for manual compliance testing. At 8.1" in diameter and 9.4" in height (with hook), it installs cleanly without disrupting your existing fixture layout.
