The Best LED Grow Lights of 2020

The Best LED Grow Lights of 2020

LED grow lights have become increasingly popular over the last several years and anyone investing in a personal indoor garden or larger commercial grow operation wants to choose the best LED grow light for their needs. LED grow lights are considered some of the best indoor grow lights available, but with hundreds of models making hard to sort through claims that they’re the best flowering or vegetative grow light, the best full spectrum grow light, or the top rated grow light of the year, you need reliable information from LED grow light experts to make a decision about what grow light is best for you..

You don’t want just any grow light for your plants – you want the best yields, best grow rates, and best density you can get. It’s not enough for an LED grow light to be popular on Amazon; it has to be the best light for you. Our experienced staff of grow light experts have done the hard work of evaluating the full range of LED grow lights on the market today to bring you a reliable review of the best LED grow lights for 2020.

Before You Buy

LED stands for light-emitting diodes. LED lighting systems produce very little heat, come ready to plug-and-play, and can produce high yields with incredible energy efficiency. LED grow lights do not require a reflector and ballast like HID lights and LEDs can last for decades, where HID bulbs may have to be replaced yearly as they begin to lose Lumens.

But one of the main reasons LED grow lights have become a standard for serious growers is the spectrum of light they produce.

Full spectrum LED grow lights will make a huge difference in helping your plants grow to their full potential and yields. Red & blue spectrums are important, but infrared and ultraviolet spectrums can be essential depending on the growth stage of your plants. The light’s power is also an important factor, but different wave lengths are needed to be taken into consideration to ensure maximum growth.

You’ll also want to take into consideration the amount of space you need to cover with your LED lights. Every LED grow light will have a range of space that it effectively can cover, so it’s important to measure your grow space down carefully. Then you can research and read reviews for LED lights can actually cover your grow space efficiently and effectively.

Another factor when choosing the best LED grow light for you is durability and electrical efficiency since an LED grow light will typically operate for 12-18 hours a day. Remember, when researching LED lights you’ll want to note the total output. The more light your new LED light actually gives off, the bigger yields you should get, so choose the most powerful LED grow lights (within reason) for your grow space.

The Best Full Spectrum LED Grow Lights of 2020

NextLight Mega

The “Mega” in the NextLight Mega’s name doesn’t mean it’s huge in size; it’s called the “Mega” because of its enormous production power and large footprint it provides for your canopy. It’s the perfect grow light for gardeners and growers who are looking to cover a large area while keeping power consumption down to a low 650 watts.

Because it’s a full-spectrum light that uses only white LEDs, the NextLight Mega doesn’t have separate settings for vegatative and bloom/flower cycles. It has a better spectrum with the same coverage area as a 1000 watt high pressure sodium (HPS). The NextLight Mega has one of the largest coverage areas of any 1000 watt equivalent LED light on the market and with a PPF of 1400 umol per second / 2.15 PPF per watt, it’s also one of the most efficient full-spectrum LED grow lights in the industry!
