Anyone have any experience with these??

yeah i use growbright lamps..but you still need the ballast and the hood or do you already have that..this is the whole system with everything http://cgi.ebay.com/NEW-1000-watt-HPS-GROW-LIGHT-w-AIR-COOLED-HOOD-COOLABLE_W0QQitemZ390050225148QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item5ad0ce1bfc&_trksid=p3286.c0.m14&_trkparms=65:12|66:2|39:1|72:1205|240:1318|301:0|293:1|294:50

but remeber what i said before..it bottom of the line stuff and a magnetic ballast just do a lil google on the differece between the two

Forgot to mention, already have the ballasts and hoods. So these are good bulbs for the $$$??

yeah man its a good bulb for the money..i think my bulb was like 120 but growbright is a good product..just remember you get wha tyou pay for in anything..BUT if thats all teh money you have then you ahve no choice
