Do lighting inverters ensure constant illumination of high pressure sodium and other HID lighting fixtures?
Only those lighting inverters that deliver voltage regulation and no break transfer, such as the “eLITE” family of inverters, will protect these lighting systems. Losing 1/2 cycle causes HID lamps to extinguish, and they require up to 10 minutes to restart! Can any UPS (battery back-up) be used for emergency lighting? NO. Emergency lighting systems are governed by UL924 standards. Only lighting inverters that have been tested and certified to this standard can be used.
