ok guys, another question...

does anyone know the ACTUAL spread and coverage of a 400w? of a 1000w?

i have read that a 400w will do a 3x3, a 1000w will do a 5x5... i took a tape measurer down and it seems at five feet, the 1000w gets a little less intense on the edges, i think maybe it's more like 4 feet....

thanx!
