By the end of the week, I'll have some 400 watt metal halide ballasts available for sale or trade that I am in the process of stripping out of old highbay gym lights. I am mainly looking to do some horsetrading for fixtures and am especially looking to trade for the following:
Line Materials Unistyle 400 with deep refractor and either no PE or set back PE
GE M250R
Any incandescent streetlight
Westinghouse OV20
GE Form 109
Two 400 watt ballasts for a 1000 watt MH/MV ballast.
These ballasts will work with H33 lamps as well.
If looking to buy outright, cost will be $45 plus S&H. PM me if interested.
