Parbright Magnetic Ballast 600w

The Parbright magnetic ballast is suitable for 600w HID lamps.  This includes HPS and metal halide lamps. 

This ballast does generate excess heat and therefore needs to be mounted properly and placed on a non flammable surface. 

Made by Venture lighting, these ballast have been ultra reliable over the years, and are a great starter ballast due to the bargain price.
