Hey guys, I've been looking around for replacement T12 VHO bulbs and there doesn't seem to be a good selection available. Most of the places don't even list the color spectrum of the bulb. Anyone know where I can find a good quality T12, particularly a 20k actinic if they make them? Who makes the best T12 bulbs? I am pretty sure I've been using bottom of the barrel stuff: these ones sell for $18 for a 48'' 110w bulb..
