Bodine's HID Backup Ballasts

The Arc Keeper® HID Backup Ballast helps 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. Bodine offers ARC Keeper models for both pulse-start and probe-start lamps.
