hmm ive only read up on the common lighting specs usually used in HID type set-ups. (lumens/watts per sq foot ..etc) I have heard LEDs being mentioned more frequently, as well as the negative.. although that does seem to make since. Havnt come across as good an explanation as to why theyre used as that :thumbsup::thumbsup: nicely put. did a simple search and came across an awesome grow with a giant led setup, but im toasted so i forget where:rasta: did you say it screws into a normal socket? guess i need to do some research...good thing i havnt bought the HPS as i have a lil time left before the sprouts will hit the screen thanks again for the idea

clf pwnage :/
