The whole light mate :smokebuds:

i run four blackstars and have had them as close as six inches to seedlings with no bad result's, except for the bs chrome i have that's another beast intirley.
i love you mr tang!:hug:
I have a 270w chrome, I actually prefer my regular BS 240's though. I've had it for several months and I still feel like I'm "testing" it out. So far my 240's outperform the chrome(the 270 FSF model anyway).
Just my opinion though killa, I know some guys that love their chromes. :smokebuds:
