How Much Does it Cost to Run LED Grow Lights?

Many hobbyists hesitate to use grow lights because they fear a massive electricity bill.
However, modern LED technology is incredibly efficient compared to old-school HPS or
fluorescent bulbs. To calculate the cost, you only need three numbers: the actual wattage of
the light, the hours it runs per day, and your local electricity rate.
For example, if you run a high-quality 100W LED for 12 hours a day at an average price of
$0.15 per kWh, the math looks like this:
$(100 \times 12 \times 0.15) / 1000 = \$0.18 \ per day$. That is less than $6 per month
to give your plants perfect sun every single day.
When you compare that small cost to the price of losing a rare tropical plant during a dark
winter, LEDs are an incredible investment. They convert most of their energy into light
rather than heat, making them safe for small apartments and shelves. You can browse our
