How much power does a 8" 450cfm can fan use? Anyone know , i looked on the box and and the fan itself but it dose'nt show anywhere .Thanks for looking.

ok another quick question ...how much power does 1000w hps use?? in amps
watts divided by volts = amps so 1000 / 120 = 8.33 and 1000 / 240 = 4.16
Ohm's law - Wikipedia, the free encyclopedia
another question about power....
Would it be safe to run 1000w hps in an older house , that uses fuses and not a breaker box?? I don't want to burn the house down
thanks for posting guys you've been a big help so far.
will the fuse blow out if thers a problem ? or will the wires catch fire?
There's something not right about BigBudBalls Elec. Calc.
If your paying .12 per K/H and you have your lights on 12 hours a day, that's $1.44/day times 30 days is $43.20.
He's got $36 listed.
