also was reading through my cervantes bible last night and came across this that people should know if theyre using these kinda flood lights that i am... "Beware of manufacturer reseller web sites making outrageous claims about CFL performance. The most common exaggerated claim is found at the Lights of America site about the 65w Florex security lights. The package claims the lamp produces 6825 lumens, but an asterisk directs you to the bottom of the box and explains that these are "brightness lumens" not "photometric lumens" A look at their website shows that the 65w bulb produces only 4500 lumens. We tested them and can agree with 4500 lumens." just thought that was interesting since these are exactly what i bought lol. so while i thought i was running 13,650 lumens, it was really only 9,000. but now i added the CFLs at 1300 a piece which gives me 14,200. just about 3,500 per sq foot
