ah ok! The input defines what it plugs into. The wall outlet! That's 120 volt Alternating Current at a frequency of 60 hz. That's what we all have in our houses in the US. The output is what you are actually using. The DC stands for direct current. The 300 ma stands for miliamp. Think of it being compared to grams and miligrams. 1 amp is = 1000 miliamps. So, 300 miliamps is equal to 0.3 amps. So...,

12v x .3a = 3.6 watts.

i understand the conversions lol. but i assumed that's what i was using. i just wasnt sure when i heard you speaking of input. but now i know my grow cab fans use 3.6 watts each. +rep for helpfulness and sweet sticky bro. i was considering making one myself but you beat me to it

hey thanks for all the great info...

one more quick question:

say your running a 400W bulb with a 400W ballast. Does the ballast also draw 400 watts as well? So when the ballast and bulb are running, there will be 800 watts of usage?

how much electricity dose a 1000watt hps thats been on for 12 hours?

Why dont you actually respect the man and read what he just spent tons of time writing.

P.S. Thanks for this thread! It definitely makes me feel better.

You would be better served to do the math yourself so you can get the hang of it. post back when figure it out and I'll double check ur math! Peace bro!

No the 400 ballast IS the power for the bulb. However, the ballast will consume some wattage on its own so you have to read the info on the ballast to see what it truly uses. I wouldn't say it would be more than 30-40 watts...

thanks very much for information, very useful i had no idea before i read yours

[stonetothebone]

thanks 4 the usefull information i got from u.this will be my second time growing and the info i got for electricity usage was all i needed to make me persuit this again last year i did it and got scared of the bill i received but now i know stealing power is not the answer and i ll keep on learning more on what i ve done wrong last year!!!

[badwolf4]

Does anyone use a GFCI? I have one as the first device in my power control panel.

I also use a Kill-a-Watt to track usage.

Thanks for the input!

sorry guys but i read the thread but i dont understant it.im a stoner and im not that good at math just wanted to no how much electricity a 1000watt hps uses thats on for 12 hour and how much money it would cost? thanks

A watt is a measure of the amount of energy used. For the power company, it is often rated as Kwh. This is a Kilowatt per hour, or 1000 watts per hour. Now this is where it gets a little weird. People often ask, so how many Kwh does a 60 watt light bulb use per hour? It uses 60 watts per hour. That’s it. So in this case, we just do another simple formula and move the decimal place back.

60w /1000 = .06 Kwh.

Power companies charge by the Kwh, as I said above. Now, from looking at your bill, you can see how much you are charged per Kwh. The national average is 12 cents per Kwh.

so, 1000 watts= 1 kwh.
12 cents a kwh
1 kwh per hour
1.44 per 12 hour cycle if my math is on, please correct if wrong.

Thanks Kushman2020, that's it. about $1.44 per hour.

i think you mean $1.44 per 12 hours. 1.44 an hour would suck lol
