new t5's!!!!!!! cheap t5's!!!!!!

ok anybody know those regular old 4 foot flouro tube fixtures (shop lights)? well they now make t5 bulbs in a t8 packaging for next to nothing as compared tot he actual t5 reflectors and bulbs. u can buy one of those normal four foot fixtures and go to this website
F30T55/850 - 5000 Kelvin - S2 Lights for the Future - Texas Fluorescents - $5.57 ea.

and they sell a flouro tube that has an added ballast on each end before the pins that converts ur normal t8 into a t5!!!! 6 bucks a bulb and ur 4 foot shop light fixture is 10 to 15 bucks at walmart! holy shit who wouldnt buy these? only thing is they only come in the 4 foot size so until they release more in diff sizes only in larger rooms will they work. but just thought id pass this on. i myself am thinking of a new setup to probably do a first time scrog. anyway let me know what u guys think?
