Started my Grow Dec13th. Last year for Dec - Feb my avg bill was $65.00. My projected bill for Jan 13' is $160.00 Thats running a 400W MH for 13 days 18/6 then a HPS 12/12 since. Running a 4" outake , 12"tower oscillator and 6"osc clip running all at least 22hrs a day ( when light is off I time the outake to go off for 15min every hour or two )
SUMMARY:
Bill goes up avg. $100 a month. this is for my area and elec cost.
SO CAL ED.

Got any pics?

Love to see them.

Come look at mine.

I learned when I moved in my first house why my parents were assholes about turning the lights off. I don't expect that that a 6" duct fan going 24/7 and my lights going 18/6 will dramatically increase my bill, as it will be only in a 4x4x6.5 tent, but I will replace all lightbulbs with cfl lights, and leave everything off, with the exception of my grow fans and lights.

I run a 400 m/h 24/7 in my veg clone room. I run constantly, 2 600's on a 12/12 with a 750 cfm fan/filter and another 400cfm fan intake and my bill went from about $90 to $160. Then I built a sauna out back with an electric heater and by bill jumped to about $190 per month, its all worth it though. I figure it only cost me about $20 to $25 a month to run a 400 mh 24/7, which is tottaly worth it, because for me a it does it all, vegges big plants, grows clones, houses my mother plants and I can put seedlings in the corner.
 
.....Came out of my room yesterday and my roommate was eatin cereal with a jacket and ear muffs on...what a pussy
Lol that's funny shit. Same here, except when I had a roomate I wasn't growing (security), but I was still cheap with the heat (im in the northern US, very cold here).

Hey everyone, a question just popped in my head and I thought this was a good thread to ask in.

I have an LED light and it says "120vac 50/60Hz 125 watts 1.6A" on the and of the housing. That's great, except 1.6A at 120V is 192W, not 125. Likewise, 125W at 120V is 1.04A, not 1.6. :!: Am I missing something, or is the power consumption really that underrated?

I may spring for a Kill-A-Watt EZ this week anyway. At least I can use it for other things.

I got one and while I have not used it much yet, a few experiments
showed that some things were using much less that I had thought.

A computer, even when not asleep will use much less that the high
power rating of the power supplies that gaming systems require.
(we all knew that those limits are to cover peaks, but the watts were
less than 100)

Let us know what you find with yours. I will post results if I ever
get around to it. My ballast has 60%, 80%, and 100% settings,
and I want to see what is really going on.

Good luck,

JD

My electric company is Con-Ed NYC...My KW rates vary every month . So even if I run the LED panel the exact
amount of time every month my bill will be different every month .

How many of you have fix rates for your electric ?

A week late, but I got the Kill A Watt. Kinda interesting and hopefully I can pay for it in power savings. Now for the results:

- The 125W LED light I mentioned pulls 130W.
- The 12W fan I am using only pulls 10W.
- Desktop PC, LCD monitor, speakers, printer, and surround unit burn up 140W just idling and about 12W when everything is shut off.
- An old 2004 laptop with a 1.8GHz Athlon idles around 30W and spikes to 60+ under load. Haven't tried my other two laptops.
- Old 50W HPS outdoor light draws about 40W initially and slowly levels off around 72W.
- A 4W LED lamp light actually draws about 5W.
- GE digital appliance timer draws 0.6W with no load.
- Analog version of that timer draws 0.7W.
- My under-bar minifridge runs around 85W.

You get the idea.

Great stuff. Thanks for taking the time.

The fact that so many devices exceeded their ratings, even if my little, was surprising.

What model Kill A Watt did you buy?

The only one that any local stores carry is the EZ model (P4600), so that's what I got. I didn't want to pay the extra $12 for it, but I must admit that the built-in memory is handy.
