150whps+100Wcomp=wtf???...

What other appliances are you using in the house. I'm sure you aren't recording the hours the other appliances are on for;
one month you could have used the tv more than the last month.

What you do is multiply your electricity tariff by the kilowatts of the appliances to work out the amount it costs to run per hour.

- 100w / 150w = 0.25kW

- 0.25 x 0.89 = 0.22 (0.2225)

So it costs $0.22 to run them each hour. If it doesn't add up, complain to your energy company.
Also, there is quite a bit a power lost in magnetic ballasts.

peak hours, or you rate gets jacked after so many kWH?

wow...glad I only pay 4.2 cents/kilowatt hour. what your paying is a total ripoff. that being said, growing mary j will cost ya. I pay $120/month and use a 400w hps, 4 fans, 2 ac's we have electric stove, electric water heater etc. Everything electric. You just have to get used to paying. It will pay for itself in the end though if you have a good harvest with a good potency/taste/aroma. thats what I think about when I think my bill is too high.

Tour state might have more taxes. My actually elecgricty bill is juat aroud 60 70 with everything running all day plus a 150w hos and a 135w led and a few fans, my taxes alone are atleast 60 70. So that could be a reason, ive lived here for ever so im not sure if rhis helps but every atate has its own tax laws on that shit

i forgot to mention the fact i ran 1,000+ watts of a window AC unit threw the whole summer and still got 78 dollars for my electric bill from the other state. here its different. i just dont get it is all. i do think the taxes and the over jack up of price after a certain hour can play a role

tap in before the meter bro!

seriously though most places probably do tiered billing which say if you go over a certain amount then the price per kwh will increase.

you dont like .8?

pay $.12 for the first 600kWH then it hikes to $.14 (or something like that. maybe .10 to start, who knows )

paying about 300/mo
