Thanks, Good Stuff.... But what do they mean about DE HQI having a higher PAR than SE bulbs. I've read from other sites that do the testing on all types of bulbs that proved that statement to be false. I can't remember which site it was, but can someone back me up.... or shoot me down. :ph34r:

I agree, this was the first site ive seen that actually says that DE have higher pars. dont believe this to be accurate. If anything SE and DE bulbs are pretty close to each other with PAR output. I do personally prefer DE primarily because of size of bulb, they cost a little more than SE/Moguls but i dont mind.
