The 8 70 of the incandescent lamps.
1000 watt hps bulb electricity cost.
For example mine is 7 cents per kwh.
One 1 1000w hps light in 120 sq ft room 12 plants in 10 gallon pots.
Led lamps last significantly longer than incandescent lamps meaning big savings by not needing to replace light bulbs every year or two.
A typical cheap 60 watt equivalent to incandescent led light bulb is advertised as providing 800 lumens lasting up to 10 000 hours at 10 watts.
Click calculate to find out the electricity cost of a single led light bulb running at 10 watts for 5 hours a day 0 10 per kwh you can also modify the input fields if needed.
If your cost is 0 15 or 0 18 you can take the total cost listed for that period and multiply it by 1 25 or 1 50 respectively.
I assume a 0 12 kwh electricity cost.
So 216kw used now multiply by cost per kw mine 07 so it would cost me 15 12 600 hours per day days 1 000 kwh cost.
Enter hours on per year.
Total kilowatts x kwh x hours per day x 30 days.
6 weeks of vegetative growth total growing period 4 months seed to harvest monthly electricity cost for vegetative growth 240 24 0 cycle monthly electricity cost for flowering growth 120 12 12 cycle.
Cost using a grow light that consumes 680 watts from the wall.
Upgrading five light bulbs to leds using 9 watts of electricity would likely cost 1 30 to power for the month vs.
24 0 24kwh day 30 days 720kwh 07 50 4 dollars a month 18 6 18kwh day 30 days 540kwh 07 37 8 dollars a month.
Now lets figure you run the 600w 12 hours a day by 30 days in a month.
Select the type of lamp i e.
You need to divide your wattage by 1 000 1 000 kilowats in 1 watt.
1 kilowatt hour is 1000 watt hours and 60 watt bulb consume during 1 hour 60 watt hours of electricity so then it costs 0 6 cent gt 60 1000 0 06 price of 1 kilowatt hour 0 6 cent.
To find the monthly cost of running your grow lights use this formula.
1 x 0.
That s 216 000 watts used now divide by 1 000 because that s how many watts go into one kilowatt.
1000 watt lamp would cost this much if you pay 7 cents a kwh.
Calculating your energy bill.
So if we were to run a 1000 watt grow light 18 hours a day with the kwh rate we gave earlier our formula would be.
