Frequently Asked Questions

How much electricity do LED grow lights use?

The actual power use depends on the light’s wattage drawn from the wall, not the advertised number. High-efficiency grow lights typically use 200W to 1000W, depending on the size of your grow space and your plant’s needs. Always check the actual wattage listed in the product specs to know what you're really using.

How far should grow lights be from plants?

It depends on the light’s intensity and your coverage goals. Lower hanging heights deliver more intense light to a smaller area, while higher mounting heights spread light across a wider area with less intensity. A common example is hanging your light around 18 inches above the canopy for balanced coverage. Always refer to your light’s PPFD chart for the best results.

How much do an LED grow light costs to run?

Your electricity cost depends on your light’s wattage and daily run time. For example, a 500W LED running 12 hours a day uses about 6 kWh daily. At an electricity rate of $0.15/kWh, that’sroughly $0.90 per day or $27 a month. Check your local energy rates and calculate based on how many hours your lights run.

How many grow lights per plant?

It’s not about the number of lights per plant but about even light coverage across your grow space. Focus on delivering the right PPFD intensity over your canopy area. A single high-output light can cover a 4’×4’ to 5’×5’ space, supporting several plants. In dense canopies, using multiple lights or under-canopy fixtures ensures even growth from top to bottom.

Do you offer energy rebates for commercial setups?

Yes, we do! Many of the LED grow lights and climate control systems we carry qualify for local, state, and utility energy rebates that help lower upfront costs. To see what rebates you're eligible for, visit our Energy Rebates & Incentives Program page.
