How Much Will a 400 Watt HPS Cost to Run?

August 6, 2022

A 400 watt lightbulb actually consumes closer to 440 watts of total power including PSU losses, so it consumes: (440 watts) x (1KW/1000W) x (\$0.10/kWh) x (12 hours) = < b>\$0.528 per day or \$192.72 per year.

How much does it cost to run a 400 watt bulb?

At an average cost of 0.09 cents per kilowatt, a system of 1,000 400-watt metal halide lights costs \$41.22 per hour. If the lights run an average of 730 hours each month (730 x \$41.22), that ends up costing \$30,090.60 each month, or \$30.09 per month in energy per light.

How much electricity does a 400 watt heater use?

It is important to note that a 400W heater consumes 0.4 units when running for 1 hour, while a 2000W heater consumes 2 units when running for 1 hour runs for 1 hour. So more heat, more watts and therefore more units consumed.

How many plants can a 400 watt HPS grow?

In general, grow lights using 200-400W can grow about 1-3 plants per light; Lamps using 500-700W can grow about 4-5 plants per lamp; and lamps consuming over 800W power can grow 6-8 plants per lamp.
