High all, i was surfing the other day, kinda window shopping for my new grow cabs and came across these flouros. They claim to have better output than T-5's, lower energy usage than HID's, and much lower heat. PLus you can get them in 4 and 6 bulb fixtures. http://www.fullspectrumsolutions.com/commercial_lighting_fixtures_35_ctg.htm Any thoughts? yes they are very pricey. peace
