There is a new product on the market from "Lights of America" the same company that makes circular flos for Walmart. It is a fluorescent Mogul base shop lamp. It uses only 65w and puts out 8255 lumens. Thats 127 lumens per watt, which is BETTER than the lumens per watt produced by a 1000w HPS, which puts out only 114 per

Anyway, three of these will put out 25000 lumens, cost you a third as much as an equivelent 250w HPS, and use 30% less energy. Check 'em out at Walmart, I just bought one for my "mother plant".
