Lumatek ballast and reflector

I have a lightly used Lumatek 1000 ballast, and a Yield Master Classic 6" reflector. The lumatek is dimmable from 1000 to 750 and 600 watts and also allows for super lumens (1100watts). The yield master is a 19in x 23in and is 87% reflective. It is not a hinged reflector. To buy these brand new it retails for over $400.
