whats the arvage cost of running a 250 watt hps light a month ?

hi im thinking about getting a 250 watt hps light but frist i was wanting to know about whats the arvage cost of running this light for a month as i really want one but dont want to run the power bill up to much lol and thanks for any help

my 400 cost me right around 20$/mnth

my 400w cost about $18 but it depends how much you get charged per kilowatt,its pretty cheap here tho

if you do a quick Google search, you can find a few different energy calculators to help you find your total cost. but remember, you have timers, and fans, they are not too much extra power, but they all add up. can i make a suggestion? you will be much happier with a 400w or a 600w. they really do not cost that much more to run, and the money you are saving by not purchasing herbs, you will have to spend on the electric. it will pay for itself in the end for sure.

ok thanks for the help guys im going to go ahead and get it as for me being happyer with a 400-600 watt hps im sure i would be and also get better yeilds from them but at this time i just dont have the space for that big of set up up to now i have been useing cfls so im sure i will be happy with a 250 watt hps for now but i hope to get a 400-600 watt hps latter on down the road again thanks for yalls help

no problem man dont forget to rep us if we helped you

if you put cfls all over your house and set appliances on economy you'll probably break even. think of it this way. before cfls everyone had incadecent bulbs. 60w here, 100w there, 3 bulbs in the ceiling fan. just lamps and overheads equalled close to 1000 watts in an apartment. 250 watts is practically nothing but if you want the exact figure you could check your electric bill.

Take your watts (400) and multiply times how many hours it will be run times days divided by 1000....then multiply that times your cost per kilowatt hour. Example:

400 (watts) X 12 (hours) = 4800 (watts/day) x 30 (days) = 144000 watts divided by 1000 = 144 KWH . If your utility is charging $.15 (cents) per KWH (kilowatt-hour) then 144 X $.15 = $21.60 per month.

Just use this formula and plug in your actual watts and actual KWH charge and you will be as close as you can get.
