Finding out how much energy an LED grow light uses is not as difficult. You must be aware of the wattage and daily operating hours of the grow light. You must ascertain how much power the light is consuming. Electricity costs are expressed in kilowatt-hours. You need to divide your wattage by 1,000.
If we assume that the true electrical power is 800 watts, then the power drain is 0.8 kilowatts per hour. You may find the cost per hour by multiplying your power bill’s kilowatt-hour rate by 0.8. Your expenses will change depending on the day if you choose time-of-day pricing, which will produce a variable hourly rate.
You must multiply the amount of light duration a day by 0.8 KWh to get the final value. This amounts to 19.2 kilowatt-hours consumed overall throughout the course of a day. Then, it’s critical to understand your electricity bill.
