Electric costs?

Can someone help me work this out. I pay 23.926 p/kwh for the first 180kwh then 10.475 an hour after that.

Ill be using a 600 watt light and was wondering how to work out approx what it would cost to run it.

A rough guess would be about $40ish per month.

Well if Lights are on 18/6 and you meant 23.926 cents/kWh

18(hrs) * 30(days) = 540hrs.
540(hrs) * 0.6 kW = 324 kWh

180 * $.23926 = $43.0668
+
144 * $.10475 = $15.084
(324 kWh - 180 kWh = 144 kWh)


=$58.15/month




at 12/12 it would be much less

12 hrs * 30 days = 360hrs
360 hrs * 0.6kW = 216 kWh

180 * $.23926 = $43.0668 (same as first time for first 180 kWh)

36 * .10475 = $3.771


= $46.84/month if you were using 12 hours.

What I would say is that it's going to be a little over 50$/month even with 12/12 Not just because of taxes and fees but also because the ballast probably grabs more than 600W @ 5amps... that's what it outputs to the light, since no conversion process is 100% efficient you have some loss (usually as heat)

You will be paying approximately $50-$65/month depending on taxes/fees/overage charges and actual kWh drawn.



I was really stoned and spent way too much time on this response

Sorry guys i meant pounds sterling.

Im am planning on having a veg room also so the 600 watt lmap would only be on constant 12/12. I just wanted an approx amunt it would cost me to run it like this?
