good info man, only thing that got me was that last pic that shows that a 92k lumen 600w hps could potentially (if heat wasn't an issue) emit 263k+ lumens? ...makes me want to invest in some cool tubes.
Thanks Twisty,can you get these made a sticky or have them added to the growfaqs.I am sure alot people can look at these get their questions answered.OPH
