bought this as part of a package deal. turns out it will not fire four 60" bulbs, only two. gonna keep the endcaps and reflectors that i got in that deal, but replace the ballast with two smaller ones since 324 watts is overkill for two 80 watt bulbs. the person i bought it from said it was rebuilt by icecap one year ago. just trying to make the money back on the ballast - $75
