Hey creeper, which one are you running? Always interested in any folks have had success with.
While there are some great deals on e-bay, I wouldn't suggest anyone go straight to e-Bay and start buying LED lights without spending some time researching and trolling through the LED forums unless you have money to burn or you're willing to take a huge risk.
There are simply too many brands, questionable vendors, and questionable quality chinese LED lights to hit the Buy button without some research. They're all willing to take your money, but as I've seen here, many LED growers end up disappointed by these cheap lights.
That said, I've been testing a few with no pressure to produce other than persona,l and the one I'm currently running my signature thread is not a bad light if you want to go that way. Even then, I'm convinced it's a great light for vegging, but the reason I'm running this thread is to show what it can (or can't) produce in flowering. I have a very controlled and detailed/logged environment and using nothing but this light (no side lighting/enhancements) through this grow. it will put to rest whether I continue with these lights for both vegging and flowering, or use them for vegging (which they do a great job of) and move up to something better for flowering.
Buyer beware for LED's on e-bay is probably the understatement of the year...
