I have 2 250W MH Magnetic ballasts, both fire HQI and regular bulbs.
1st one is a single Hamilton (old black box)
2nd is anodized aluminum with fins on top, and is a dual 250 ballast.
No brand on the chassis anywhere, so your guess is as good as mine.
Was running 3 Radium 250W 20K's with these with no issues at all.
35 for the single, 70 for the dual, or take both for $100.
