Ballasts - Standard and Emergency

The key benefit to Keystone’s parallel lamp operation is that if one lamp fails, all other lamps will remain fully powered. Furthermore, there is no need to power down the fixture to replace any lamps.  Decrease maintenance costs and hassles associated with series lamp operation.

Fluorescent emergency ballasts are able to operate one lamp in the emergency mode for a minimum of 90 minutes and are most beneficial during a power outage.  Our ballasts are compatible with 1-lamp, 2-lamp, 3-lamp and 4-lamp fixtures, with many ballast types including standard, rapid start, slim line, instant start, dimming, and electronic AC ballast - consult factory regarding specific applications

All of our emergency ballasts come with a full two (2) year warranty against defects in material and workmanship (lamps excluded).
