Lighting COB LED Electric bill question?

[Misanthrope82]

Hi, guys. I know this question is gonna vary between location, energy provider, etc, but for a rough estimate: how much can one expect their electric bill to increase by running a 1200 cob LED light (pulling 360 watts from the wall)?

I'm thinking 24/7 but if I have to 20/4

turn the tv off and sit in the dark if you have to
soryy no idea i had the all the paperwork out,cost per watt hour is x pence.mulitpy by 360x hours a day x 4 =cost/month but i got stoned and forgot about it.then the candle caught the paperwork and
good luck n keep er lit

First you have to work out what your electricity cost is per kwh.. jump on your suppliers website or check a bill?

Then work out if there's a peak/off peak times. (Or like us you have three different tariffs during a 24 hour period!)

Then work out the total draw of ALL of your devices, fans, pumps, lights, heaters, coolers, etc...

I put all mine into a spreadsheet, and did the maths that way.

2 actually... one to add up all the actual power usage (which I compared to the meter reading), and then one to do the tariff calculations...

You might also want to invest in a plug in power meter, they're not very expensive, and you can monitor exactly how much power is being drawn, and most you can setup the tariff so it will work out the costings for you too...

Hope this helps you in some way! Let me know if you want some more details or the formulas etc.

I run mine at 19/5 - 5 hours is the peak time and double the price - only thing I have going then is one fan and the water and air pumps... A total of about 100w, everything else switches off with the digital timer for those 5 hours, then back on lights and heat and fans etc. For off peak.

@archie gemmill suggueation actually plays on my mind a lot more these days - switching lights off where unnecessary, not leaving things on standby, etc. Good for the environment, too!

Simplified math using my electric rate of 0.12c a kwh. Essentially I pay $0.12 an hour for 1k watts. You are using slightly more than 1/3 of 1k watts so at my elextric rate those lights would use about $0.04 an hour. So a slight bit more than 4 cents an hour. Times 20hrs of "on" time equals about $0.80 a day to run.

Simple math below if you want to skip down.

What I did last grow...start vegging under CMH 4K bulb, start of flowering I switch to 3500k bulb. Running AC and humidifier during this time. Highest bill $150ish...includes all my appliances on property and water well.

Late into bloom I turned on 2 autocobs along with the CMH 3500k. AC and Dehumid on humidifier off. Bill increased $10...prolly from dehumid.

Final bloom stages CMH off; both cobs running, ac and dehumid. Last bill was $120.

Simple math:
CMH=energy hungry
CObs=much, much less energy consumption.

OOPS...20/4 schedule the entire cycle
