I have 275+ air cooled light reflectors (xl 6" Brand) in my way, $1000 takes em all or make an offer for however many you'd like. Some still have 600watt bulbs in em. Also have approximately 230 used 600watt digital ballasts... same deal for them 1000 bucks takes em all or make an offer for what you need. I changed to LED so this stuff is no use to me anymore.
