Keystone LED Emergency Backup Kits

Keep your building safe for when the power fails with Keystone Technologies LED Emergency Backup Kits. They are designed to automatically detect the electrical load of the LED fixture and adjust the output to the appropriate level. The emergency backup kit is incorporated with Keystone's Constant Wattage LED Emergency driver that will help give you a piece of mind in knowing your fixtures will operate when needed most. They are designed to operate at temperatures as cold as zero degrees Fahrenheit and are UL 924 listed, which makes them suitable for use in both damp and dry applications. Also featured is both short circuit overload and open load protection. The Keystone KT-EMRG-LED-5-500-K1 provides 500 lumens of illumination, while the Keystone KT-EMRG-LED-12-1200-K1 delivers an impressive 1200 lumens of light output, both lasting a minimum of 90 minutes.
