I ran down to WallyWorld and bought a pair of these lamps, but now I am wondering if I have screwed up ... I jumped at the chance to get these lightweight lights, as my present 8-tube flourescents (4-foot 40watters) are a pain in the ass due to their weight .... but, I have a present total output of 320 watts, with 27,200 lumens (8-square feet cabinet)... these two new lights will have 1000-watt "equivalence", but only 9,100 lumes .... correct me, but aren't the 'lumens' what I should really be aiming for ?? ... need informed answer to this, please .. :smokin:
