Hi, In one our projects, we intend to install metal halide high bay lighting and would like to install a UPS as back- up to normal supply.

I would like to know if any one used an UPS as back up for pulse start metal halide high bay lamps. I would like to know the make model of the UPS systems and your experience with such system.

I have used numerous Lighting Inverters for backup of Metal Halide Lighting in Warehouses with excellent success. You don't actually need a full blown UPS, just an Inverter that has a fast enough transfer to maintain the Lamp Arc. Liebert, Myers Power Products, Chloride, mcPhilben and Lithonia, all make them in single phase or three phase, anywhere from around 1kVA up to 150kVA. There not cheap, but niether is the quantity of emergency battery lights required to meet 1fc average requirements in current Codes.
