400w metal halide ballast box

This actually was a highbay fixture that was missing all its parts except for the ballast/socket assembly. I figured it would make a nice lamp testing fixture/pre-contructed ballast box. I have four different lamps I can use with this: A Sylvania 400w metal halide (probe start), Sylvania 400w mercury (/DX), a 360w HPS retrofit lamp and a 400w mercury black light.
