How Much Energy Does An LED Marijuana Grow Light Save?

I know more and more people that are looking into getting LED grow lights due to the amount of energy they save. Whether it’s to save money, or to lower an indoor garden’s carbon footprint, or both, more growers are considering purchasing one or more LED grow lights for their garden. Electricity is one of the largest, and often the largest, expense for an indoor marijuana garden. You have to pay for lights, and for fans and AC to cool the room because of the added heat from those lights.

LED grow lights can help save money directly because they take so much less energy to operate. LED lights also emit far less heat compared to a HPS or MH light, which further reduces the energy consumption of the indoor garden. So just how much energy does an LED light use compared to a traditional light? And how much money is saved? See the chart below, broken down by state:

    Very good news, even though it means the grow light I have stored away is an expensive white elephant

  • Yoda

    This is great and all but how much does an LED lighting system cost compared to an HID? How easy is it to install? And lastly can you get the same results?

  • Electrician

    This is very deceiving because it assumes that a 390W LED is equal to 1000W MH. It just isn’t possible. The strength or intensity of any light can be roughly measured by the total power draw, regardless of the type.

    the LED lights target only the nm of light necessary for photosynthesis so that is why you need less wattage to do the same amount of work. mh and hps waste a lot of energy in the form of excess heat, so there is wattage going towards that which is not the case with the LEDs. thx for the calculations.

    It would have been nice to see a lumens per watt output chart to coincide with this table. There needs to be a clear gain or the savings are all for not.

    We have a revolutionary game changing new LED 2.0 grow light that replaces 2 1000 watt HPS grow lights and generates 80% less power and heat..Finally a Full Spectrum LED High intensity LED Grow light! text 727-565-8775 brentex@gmail.com for detailed specs and videos

  • I do not agree that. You should use the 600watt LED at least compare to 1000watt HPS. I tried many many time testing on the performance of power consumption, intensity, lumen, PAR, wavelength, color bands…..
