Galaxy Electronic Ballast 250 Watt 120/240V
 

This is a DUAL ballast, but only ONE SIDE is working. We got a replacement, and they told us to keep this one.

So it will only power one lamp (not sure whats wrong with the other side)

Asking $75

Purchased for $285 in the US originally, just trying to recoup the shipping cost we paid for the new one :)
