what was your total yield of that lamp?? thanksI've been using Green Light Solution's 400W Magnetic Induction Light just finished my first harvest totally beat a 1000W HPS by far will post some pics son. Also I hear they will be coming out with a 500W induction fixture I cant wait to see how that out performs and 1000W HPS! In mean time check out this vid of GLS's 400W vs. 1000W Hortilux HPS http://youtu.be/Ilw9Br_xq3Q
