Now consider a 1200w LED lamp with 4ft x 4ft grow coverage for an indoor grow room. It would cost roughly $525.66 to run this 1200w LED light for 12 hours a day using the same electricity rate.
The national average is approximately $0.13 per kWh. A 320-Watt LED grow light probably uses almost 6-kilowatt hours per day during the vegetative stage. In flowering, the same light uses almost 4-kilowatt hours a day. Overall, the cost of electricity for this single grow light is approximately $4 per week.
How Much Power Does a Cannabis Grow Room Consume? According to the Northwest Power and Conservation Council (NPCC), indoor commercial cannabis production (also known as a cannabis grow room) can consume 2,000 to 3,000 kilowatt hours (kWh) of energy per pound of product.
A light system will increase your electricity cost -- the exact amount depends on the size of the system and the number of hours operated. However, since most grow lights are so energy efficient, you are getting huge amounts of light (and growing power) for your money!
The Answer. A 1000 watt Led grow light, running 18 hours a day over a 30-day period at a cost of 14.21 cents per kWh will set you back $76,24. Running grow lights can be expensive.
The average price in the USA is 12.83 cents per kilowatt-hour ($0.1283/kWh). This is the daily cost to operate the G8LED C3 grow light. Multiply by 30 to get the monthly operating cost. In addition to the lower power usage of the light, the lower heat output means less HVAC and more savings.
Multiply $0.0195374 by the number of hours you plan to run the lights (14 hours). The cost to run the lights per day is $0.2735236 or $8.20 per month. If I have an HID (high intensity discharge) light with a 600 watt bulb in it, using the same method of calculation, it would cost me $30.90 per month.
Let's say you have a 60-watt incandescent lightbulb and you are paying 12 cents per kWh of energy. Leaving the bulb on the whole day will therefore cost you: 0.06 (60 watts / 1000) kilowatts x 24 hours x 12 cents = approximately 20 cents in one day.
2 month plants should give about 40g per plant, so with about 9 you'll be able to easily fill a square meter and get up to 400g per 600w light. 3 month autoflowering plants grow much bigger, however, so you should only plant 4 per 600w light.
However, as a rule of thumb, you would need 200 to 300 watts of solar panels for every 1 kWh of daily energy that your grow lights consume. For example, if your grow lights use 2 kWh of energy every day, you would need 400 to 600 watts of solar power to offset that energy consumption.
670×0.15×12×7×10= 84,420(pence) So this means that your '600w' light will cost you a total of £84.42 in electricity over a ten week cycle.
The average Commercial Grow Room Setup Cost is around $42 per square foot. But your cost can fluctuate based on many factors, from building type to workflow design.
A 20W grow light that's on for 12 hours a day costs me 1.15USD/month. A 40W grow light that's on for the same number of hours will cost me 2.3 USD/month in electricity. The higher the wattage, the higher your electricity bill. All grow lights consume a certain amount of electricity.
These lights range in power from 100 to 1000 watts. The 400 and 1000 watt lights are the most useful. A 1000 watt grow light can light up an area of about 7 feet square when the light is suspended 2 feet above the plants. A 400 watt light would work for an area of about 4 feet square.
Dominating the hydroponic energy use are the heating and cooling loads at 74,000 ± 10,000 kJ/kg/y, followed by the energy used for the supplemental artificial lighting at 15,000 ± 2100 kJ/kg/y. The circulating pumps contributed the least to the total energy use at 640 ± 120 kJ/kg/y.
A LED light bulb uses just seven to ten watts while a fluorescent light bulb consumes 16-20 watts, an incandescent light bulb will use 60 watts typically and cost about 0.6 cents an hour to run, according to the energy use chart.
Normal Night light Uses Most Electricity
Compared with LED night light bulbs, the traditional incandescent night lights or neon night lights use more energy, it's about 3 to 7.5 watts of energy while running. While LED night lights can use less than a single watt.
A “normal” incandescent bulb costs about 0.75cents per hour, and LEDs or CFLs cost only one-sixth of that – so leaving the lights on (either overnight or while you're at work for the day, say both are about 8 hours) costs you roughly 6 cents for a normal light and a bit over 1 cent for modern bulbs.
Currently, most of these lamps operate at 300 to 600 watts per inch with some newer systems using lamps that generate up to 1000 watts per inch. So a 30 inch UV bulb may be capable of an output of 30,000 watts. They also operate at very high temperatures (850 to 950 Celsius or 1550 to 1750 Fahrenheit).
A 50 watt traditional bulb that runs for a single hour will use 0.4 kWh/day. This means that working for 8 hours per day, it will consume 146 kWh/year. If your energy company charges 15 pence per kWh, the 50 watt bulb will cost £21.90 per year to run.
At an average cost of 0.09 cents per kilowatt, a system of 1,000 400-watt Metal Halide fixtures costs $41.22 per hour. If the fixtures run an average of 730 hours every month (730 x $41.22), it ends up costing $30,090.60 every month or $30.09 per month in energy per fixture.
