I hate to beat this issue to death but as much as i've looked around i can't find a good answer.....
would 6 42watt cfl's use more or less power then one 150watt hps bulb?
both setups would put out approx. the same number of lumens (apprx 15,000) but I can't find a good answer on which setup would use more power (preferably in amps).
i did some math in my head and figured out that the cfl setup would draw about 2 amps....using the rated wattage (42watts). however on a cfl i have in my house now (a 30w) the bulb states it uses .5 amps (much higher then the rated wattage would apply)...by estimating how much my cfl would draw using this number i get around 4-5 amps....
I guess my REAL question would be....how many amps does a 150 hps take to operate?
and while i'm at it i might as well ask.....for a 2 plant setup which would be more efficient and/or have a better light distribution for the two plants.
