I've got 3 400 watt MH ballasts gifted from a friend. He was using it them as aquarium lights, but has LED's now, so the current bulbs are like 20,000K spectrum.
The original bulbs fire, as does another old bulb I have laying around, however I bought some 7,500k bulbs, and they flicker once or twice when I turn the ballast on, and again when I shut it off, but they never fully ignite and fire up.
Anything I'm missing here?
