How to calculate electricity consumption of your lights and other appliance πŸ’²πŸ’‘πŸ’»πŸ“ˆ


Here’s the formula for calculating the kilowatt consuming by your appliance (true watts consumption)

The formula is : Number of hours of utilisation Γ— Number of days Γ—( Number of watts have your lights Γ·1000) example : 300 watts Γ· 1000 = 0.3 kilowatt. A schedule of 18/6 for 30 days gone a give :18Γ—30Γ—0.3= 162 kilowatt for 30 days. That’s gone a give you how much kilowatt your lamp or appliance are consuming in a definite time, just multiply by the rate of your local electricity distributor charging.

Hoping that’s gone a help as much as possible my fellow grower’s :wink::innocent::v:


Autoflowering first grow
How much electricity is a noticeable amount for an electric company?

Good info @Niala I’m sure that will be helpful


Thanks @Countryboyjvd1971 :+1::v::innocent:


Sure thing bro
I’m sure a lot of the peeps where trying to figure this out
You have more patience than I do for teaching lol
Good for you :+1::v:️️


@Swan1234 this might interest you I saw your thread and saw this


Hey! Bro, just trying to help :wink: :innocent: And I love to do so, for fellow grower’s who need it :innocent::+1::v:


It’s already done @Countryboyjvd1971 :wink::innocent:


Yep lol @Niala @Countryboyjvd1971


@Niala, great info,even tho I’m an outdoor grower, and for the cost of it ,I will be abkevto work out if viable option for me through out winter thank you


handy dandy info @Niala thanks for the input to find the output!!lol


You’re welcome @Coltfire and thanks for the good word :grinning::innocent::+1::v:


Lmao, tiguidou lyloo :joy: :sweat_smile: :wink: you’re welcome @BIGE :grinning::wink::innocent::v:


Wow… my HPS will cost me $26.54 per month to run.
Mine sleep during the day, during the costly time to use electricity here.
They’re awake mostly during the cheap time!

Ooh, and btw, I wired it 240v.


You probably forgot to take the royalty fee in your calculation because I do not know anywere who’s local electricity compagny charging total around 8. 23 cents per kilowatt/hour. If you do, you are a very lucky man.

I don’t know what you’re trying to achieved here, however, I don’t wish to play that game, and sincerly wish you all the good and a happy growing @Traumamedic



Well for one, I told you I wired at 240 volts.
It’s only drawing 1.2 amps.
And for two, we belong to a co-op.
And three, I get a discount on electricity because I work for the electric company.

And what game are you talking about playing?
I never directed anything at you!


Cool, so you are a lucky man, sorry if I misinterpretated your intention and apologise if I hurt your feeling in anyway possible. :v::innocent:





Lmao :grinning::+1::ok_hand::v::innocent:


What other math do we have to do if using 240?


Thank You @Niala… This formula is exactly what I needed for my new grow room,…
I’m not sure how to link my journal…

Thanks Again… :deciduous_tree::dash::upside_down_face::sunglasses:
