whats the HPS Cost on your bill

just wondering how much an hps cost to run on 12 for different people..how much has you bill increased..
with you watts and hours please post...

right now I have 2 400W lights going 12/12....... my power bill went down, when I had one on 18/6 and one on 12/12, my power bill was unchanged from before I started growing......

do some research on how to combat the electricity and you wont have to worry about it as much.

im running 1 400watt hps lamp and since 1 of my roomates went home for the summer its dropped, even with the light at 12/12... So i mean, its not using all that much for 1 light...

Almost equivalent to say...a 400 watt powr supply from a computer?...

My 400 watt raised my bill 8.50 bucks a month. With my fans it went up to about 11 bucks and some change.

yea, there cheap my 400watt hps ran me 10-15 a month, nothing to worry about there

Cost of a light see my example:

kWh = Watt of light / 1000
cost for hr = price per kWh x kWH

1000 HPS / 1000 = 1kWh

12/12 photo period:

1kWH X $0.1178 = $0.1178 = Cost an hour
$0.1178 x 12 Hrs = $1.4136 = Cost a day
$1.4136 x 30 days = $42.408 = Cost a month

18/6 photo period:

1kWH X $0.1178 = $0.1178 = Cost an hour
$0.1178 x 18 Hrs = $2.1204 = Cost a day
$2.1204 x 30 days = $63.612 = Cost a month

1 kWH cost 0.1178 where I live.

There is no way on earth a cop or power company will even blink at a 400 watt increase or even a 1,000 watt increses,i dont even think about taking steps to conserve power in order to hide my light useage till im over 2,000 watts 24/7.
