Depending on your electricity prices, a 400 watt HID will cost $200 â $400 each year of use, plus the cost of replacement bulbs. LEDs meant to replace 400w HIDs average around 180 watts.
If your trying to find out how many Kw/h your going to use. First figure out how many watt â¦ s your running. 1000W = 1Kw so divide total number of Watts by 1000 So for a 600W light 600W/1000= 0.6Kw/H So if you use your light for an hour thats how many Kw you will use for an hour.ou are billed based on kilowatt-hours. Your light is 1 KW. If you had on continually for the month that would be about 30 days x 24 hrs = 270 KWh. An average cost per KWh is â¦ about 12 cents so your cost would be about $86.40 for continuous use per month.
