HID Backup Ballasts
ARC Keeper HID Backup Ballasts help eliminate downtime in HID metal halide lighting systems by supporting the lamp arc for up to two minutes in the event of a power disturbance. Two minutes is generally enough time for a disturbance to pass or for a generator to respond. No arc loss means no need for lengthy restrike periods common to HID systems. Philips Emergency Lighting offers ARC Keeper models for both pulse-start and probe-start lamps that are CSA Certified, UL Listed and 120/277 VAC.
