Energy Savings? Great. Financial Savings? Even Better: The Benefits of Switching to LED Grow Lights

As the world moves towards more sustainable practices, one area seeing significant improvement is indoor agriculture. Green Rebates is helping farmers and cultivators lead the way by empowering them to be able to make the switch to efficient lighting and environmental control systems with unique energy rebate and incentive programs.

Traditional HID (High-Intensity Discharge) lighting, long the standard for indoor grow operations, is being replaced by LED (Light Emitting Diode) grow lights. This shift isn’t just a win for the environment; it’s also a big win for your wallet. Let’s explore how switching to LED grow lights can lead to substantial energy and financial savings.

The Efficiency of LED Grow Lights

LED grow lights are revolutionizing indoor farming by offering unparalleled efficiency. Compared to HID lighting, LEDs consume significantly less power. Here’s why:

Lower Power Consumption

LED grow lights are designed to convert more electricity into usable light for plants, wasting less energy as heat. This means that LEDs can produce the same amount of light as HIDs while using up to 60% less energy. This reduction in power usage translates directly into lower electricity bills.

Higher Light Efficiency

LEDs offer a more targeted light spectrum, which means they can be tuned to emit the specific wavelengths of light that plants need for photosynthesis. This precision ensures that less energy is wasted on producing light that isn’t beneficial for plant growth, further enhancing their efficiency.

KWh Savings with LED Lighting

One of the most tangible benefits of switching to LED grow lights is the reduction in kilowatt-hours (KWh) consumed. Let’s break down the savings:

Example Calculation

Consider a grow operation using 10 HID lights, each consuming 1,000 watts. If these lights run for 18 hours a day (a typical light cycle for vegetative growth), the total energy consumption is:

10 lights * 1,000 watts * 18 hours = 180,000 watt-hours, or 180 KWh per day.

Switching to LEDs, which might use only 400 watts each, the calculation changes to:

10 lights * 400 watts * 18 hours = 72,000 watt-hours, or 72 KWh per day.

This switch results in a daily savings of 108 KWh. Over a month (30 days), this equates to:

108 KWh/day * 30 days = 3,240 KWh saved.

With electricity costs averaging around $0.12 per KWh, this amounts to a monthly savings of:

3,240 KWh * $0.12/KWh = $388.80.

Reduced HVAC Costs

Another often overlooked benefit of switching to LED grow lights is the reduction in HVAC (heating, ventilation, and air conditioning) costs.

Less Heat Output

HID lights emit a substantial amount of heat, necessitating robust cooling systems to maintain optimal growing temperatures. LEDs, on the other hand, run much cooler. This reduced heat output means your HVAC system doesn’t have to work as hard, leading to further energy and cost savings.

HVAC Savings Calculation

If an HVAC system is required to remove the excess heat generated by HID lighting, and it typically consumes around 0.75 KWh to remove 1 KWh of heat, the savings can be substantial. Using our previous example, the reduction in daily energy use (108 KWh) would also reduce the HVAC load:

108 KWh * 0.75 = 81 KWh saved daily on HVAC.

Over a month, this is:

81 KWh/day * 30 days = 2,430 KWh saved.

At $0.12 per KWh, this results in additional monthly savings of:

2,430 KWh * $0.12/KWh = $291.60.


Switching from HID to LED grow lights is a smart move for any indoor grow operation looking to cut costs and reduce environmental impact. The efficiency of LEDs leads to substantial savings in power usage and HVAC costs, translating to thousands of dollars saved annually. By investing in LED grow lights, you are not only making a choice that benefits your plants and your bottom line but also contributing to a more sustainable future.
