Just want to test a ballast I got off ebay. I picked up a Lumatek 400W that has the selector for 250, 250SE, 400, and 400SE. I checked it with a Lux meter and a Kill-a-watt, while using an old 250w bulb. There was no wattage or Lux change going from 250 to 250SL(Super Lumens). The bulb did flicker so I know the setting changed when I turned the knob. The vendor says I won't see a change until I use a 400w bulb, which I don't have yet. This doesn't sound right to me. I can see why I can't/shouldn't turn it to 400, but I'd expect it to run a few extra watts through the 250.
Anyway... If somebody has an old 400w single end bulb for cheap sale or as a loaner I'd appreciate it. I'm in the Denver/Aurora area.
