awhile back, a thread was in here, announcing a big CFL yard light, available at WalMart, ((in California), that is under special pricing from PG&E (local electric company), it draws 85 watts, and it claims equivalency of a 500-watt incandescent ... (I have no idea how accurate that claim is, seems a bit optomistic, but it IS bright) ... anyway, it is just a large, powerful CFL, blue spectrum, great for vegging ... and, because the electric company is underwriting the cost, they are like $12 apiece, fixture and all, ready to install a plug ... the CFL is a Mogul base type ... :smokin:
