I have 3 new 10k SE XM bulbs and for ballasts I have an old hamilton hqi ballast, a bluewave 3 hqi ballast and this new dial a watt ballast. Both hqi ballasts will light any of the 3 new bulbs, the dial a watt won't start any of them (most of the time)
I have changed the settings on the dial from normal 250w to the hqi but neither setting will work consistently
