I have 3 1000 watt magnetic ballasts for sale 2 are switchable and in great working condition have about one full grow on one is a little older and the standard looking vented box with a handle That one is $50 other one that is newer will be $55 . both come with 120v power cables. also have a lumatek 400 watt digital with a cool tube that the glass broke out of but still works . comes with a MH and a HPS bulb for $90
the other 1000 watt is a HPS only but it turns on and will light up but turn off after about 30mins - 1hr . this one is $20 for parts or someone that knows how to fix it .
