Hello Folks, the new format seems to be working! Anyway seeing how I'm still behind the new technology,I still use MH lighting. So this time of the Year I change out the old bulbs. I have an old electronic ballast that won't light the new bulbs. However It will light an old bulb. Just wondering why. The old (1 year) and new bulbs are Radium 20 k's. It's no big deal except a new ballest runs about 150$ !
