Check out the GroLux series(By Sylvania) : " The first bulb designed from the ground up , strictly for plant growing" I use them with spectacular reults.

on my 3rd 600 watt Hortilux bulb , and i dont like them.
they get really dim about 5 months in , i can only get 2 grows out of them

The grow bright bulb is better based on the linens and the color spectrum it gives off.. too much red isn't all that great. Get a bumd that has alot of blue and red spectrum for optamun growth

i bought the Digilux bulbs one each hps mh
they are great so far and nice price

this is a thread i created a while back i dont think it has that first bulb u mentioned but it has a lot of others... iif you find the specs to that bulb post it on my thread please.... hope this helps.... ------> Specs And Comparisons For 600w HPS Bulbs

ushio is best

Growbright is a work horse!! I've had electric spikes, turned it off an on very quickly by accident (not just one time) which usually burns the sodium bar, but not this one! I've gotten about 3 cycles of good yields of it and still running, not to forget it came used with a GH ballasts I got from ebay. I'm ordering 2 more as we speak btw. I use Hortilux for my 1000W systems, rock solid too although I'm more carefull handling it. I'll do a 1000W versus to see what's the deal.
