Xtrasun XT Luminaire Grow Light Hood with Two 400w HPS Bulbs

Selling an Xtrasun XT Luminaire Grow Light Hood, and two 400w HPS bulbs. The Hood has a hammered reflector for strong and even light distribution. It can take bulbs up to 1000w, and includes a tempered glass lens. It`s in good condition.
There`s also a 400w HPS / MH ballast that you can have as part of the deal, but the ballast isn`t working correctly. It emits a humming noise, and won`t power a bulb at full brightness. I don`t know whether this can be fixed.
These came from an estate sale, so I don`t know how much life is on the bulbs. I tested them with a different ballast, and they both fire up.
