When investing in grow lights, it is important to think long-term. Two key considerations should be made when you purchase grow lights: What kind of yields can a light produce? How much does it cost to operate? Smart cultivators understand that their profit is determined by the size and quality of their crop minus the expenses of consumables like electricity, fertilizer, clones, etc.

An important concept to understand is that higher light density leads to greater yields, which creates more profit per harvest — and LEDs achieve this while also saving money by lowering operating costs compared to HPS/CMH lights. By switching to higher output and more efficient LED horticulture lighting, you can save hundreds of dollars per light per year.

Do LED Grow Lights Use a Lot of Electricity?

LED grow lights are very energy efficient and they do not use a lot of electricity. Traditional HID grow lights consume a ton of electricity, in fact paying for the electricity used to be one of the major costs of homegrown plants. Each HID bulb can consume anywhere from 100 Watts to 1,000 Watts, so it depends on the size of your grow, but switching to LED grow lights can save you 50% to 70% in actual power consumption.

Many LED grow lights are still described in the wattage of their HID equivalent in terms of brightness. As you can see in the list above, though, many brands do not use the exact same wattage equivalent in their naming conventions — Make sure to check the manufacturer’s specifications on your grow light before purchasing.

It is a good idea to go by the recommended coverage area for a particular LED grow light as opposed to the HID equivalent, as this measurement is far less subjective.

Just keep in mind you will need to adjust the hours per day based on vegetative vs flowering light schedules.

Mars Hydro SP-250 LED Grow Light

Features:

This plant growing lamp uses 240 watts, which is equivalent to 1200w traditional lights. The led plant grow Lights will cultivate record breaking growth, both in speed and quality. Mars Hydro LED Grow Lights have high-output LEDs which is full spectrum that provide optimal light for seeding, vegetative and flowering cycle , as well as herbs and other edibles. Works very well with all stages of plant growth. Makes your plants grow at an accelerated rate and develop better.

ECO Farm 240w Samsung 301H Waterproof LED Grow Light Bar

Features:

This ECO Farm LED grow light has a higher light intensity, less light decay , better lumens and PAR values than ordinary leds. It runs at a lower temperature and can bring higher energy conversion and longer life. This grow light is a full-cycle lighting solution for all growing environments including wet situation and is ideal for greenhouse or indoor lighting. The actual power is 240watt, light efficacy is up to 2.8umol/W. No fans no noise and waterproof function. Lots of heat sinks and hollow body ensures maximum heat dissipation. No additional fan zero noise. Otherwise, the plant grow light uses advanced waterproof power supply which is installed outside of the light and it is easy to be replaced. Light board adopts sealing technology, so whole plant grow light can reach IP65 water resistant level. No need to worry about the humid planting environment to damage plants light

PHOTOBIO T 300 Watt LED Grow Light

Features:

PHOTOBIO•T can be applied indoors or greenhouse as a direct 600W HID alternative or retrofit. Patented PHOTO•PRO Photon Regulating Optics ensure the most efficient delivery of plant biologically active radiation (PBAR) to the plant canopy. PHOTO•LOC Light Output Control allows precise control over the photons that are delivered to the plant canopy when used in conjunction with a 0–10V controller. In greenhouse facilities, PHOTOBIO delivers consistent optimal PPFD levels throughout the day while saving energy. Just pair PHOTO•LOC with an environmental control system that utilizes a quantum sensor to measure light entering the greenhouse and automatically regulates light output in real-time.

Conclusion

LED Grow lights have multiple advantages over HID grow light when it comes to the overall consumption of electricity and the short answer to the question “Do LED Grow Light Use Less Electricity?” is “Yes” they do. Apart from this, the durability and low running costs of LEDs increase the savings in a wider perspective. The heating bills will also go down without worrying about replacing the bulbs all time.

Although the initial cost of LEDs are more than HID grow lights, if we compared their benefits like durability, energy savings and longer life span, it makes them a fruitful investment.
