You need to choose the best LED grow lights here in 2019? This list will include LED grow lights that have a flowering coverage area of four foot by four foot and are best for a full cycle grow from seedling through flowering.

Horticulture Lighting Group HLG 550 V2

Horticulture Lighting Group HLG 550 V2

Let’s start with one of the most efficient LED grow lights on the market today.

The HLG 550 V2 by the Horticulture Lighting Group absolutely makes the list this year as one of the best LED grow lights in 2019. It has four quantum boards that have a total of 1,152 top bin Samsung diodes. It is a white light full-spectrum grow light that comes in either 3000k or 4000k. The 4000k is recommended for plants in the vegetation stage and the 3000k has a better light spectrum for flowering. Most growers choose the 3000k of growing from seed to harvest in the same grow space. Now let’s talk PAR output.

The HLG 550 V2 has a photosynthetic photon flux, or PPF, of 1178 micromoles per second. PAR efficacy comes in at 2.5 micromoles per joule. The LEDs are powered by a Mean Well driver that is dimmable to 50% intensity. Since the grow light has a dimmer, the water draw from the wall will vary from 190 watts to 480 watts, depending on if the light is fully dimmed or maxed out respectively.

This LED grow light was designed and is manufactured in the USA. It comes with a three-year warranty.

Horticulture Lighting Group HLG-600H DIY kit

HLG 550 V2

This LED grow light is very similar to the HLG 550 V2, although this is a DIY kit, not a complete fixture, so you need to use a screwdriver and some wire snippers to assemble it. What are the differences between this LED grow light and the HLG 550 V2 LED grow light? The HLG-600H is more powerful. It distributes 1500 micromoles per second, which is 20% more than HLG 550 V2. With the added intensity, it also draws more from the wall, 620 watts. Although PAR efficacy is slightly lower at 2.4 micromoles per joule.

The recommended coverage area for veg is also different. Seven feet by seven feet for the HLG-600H, while the HLG 550 V2 is listed to cover eight six foot by six foot grow space. The last major difference to call out is that HLG-600H comes with a one-year warranty versus the HLG 550 V2 comes with the three-year warranty.

The Green Sunshine Company Electric Sky ES300

Electric Sky ES300

The Electric Sky ES300 by The Green Sunshine Company was released last year and quickly became popular among both home and commercial growers. It uses top bin, mid-power wideband diodes. The spectrum is a unique GS1 wide-band spectrum that includes IR. This LED grow is excellent at spreading the light evenly across the coverage area. Two of these lights will cover a four-foot by four foot grow space. The ES300 has a PAR output of 600 micromoles per second in a PAR efficacy of 2.0 micromoles per joule, all while pulling only 300 watts from the wall. I personally grow with this light and my plants love it. Feel free to check out the videos on my YouTube channel to see the results that I’ve gotten from using it. This LED grow light comes with a three-year warranty.

Gavita Pro 1650e LED ML

Gavita Pro 1650e LED ML

Gavita, who is mostly known for their HID grow lights, has joined the LED grow light market. The Gavita Pro 1650e LED ML grow light comes in at a 2.6 micromoles per joule efficacy in a 1650 micromoles per second PPF. Wow. But this full spectrum grow light has diodes lined up on eight bars for even light spread and includes enhanced reds to benefit in flowering. The unit pulls 629 to 646 watts from the wall, depending on which voltage you get. And it’s passively cooled. It is compatible with both the Gavita Master EL1 and EL2 gen two controllers, so you can fully control things such as the light schedule, dimming and sunrise/sunset features. This fixture is backed by a three-year warranty.

California LightWorks SolarSystem 1100

The California LightWorks SolarSystem 1100 LED grow light makes the best LED grow light list again this year. This LED grow light uses top bin OSRAM diodes, has a PAR output of 1730 micromoles per second PPF and a PAR efficacy of 2.2 micromoles per joule. It pulls 800 watts from the wall full power and the light is cooled via four fans on the top of the fixture. For an additional cost, you can get the solar system controller. With the controller, you can fully customize the amount of UV, IR, red, white, and blue light. The controller also has a sunrise/sunset feature. With this feature enabled, the grow light will slowly become brighter when the unit first turns on to emulate sunrise. Then to emulate sunset, the brightness will reduce slowly prior to turning off. This is one of the LED grow lights that I currently use in my grow room. I’ve been using it for well over a year now and I’ve gotten some excellent results with it. This LED grow light is made in the USA and comes with a five-year limited warranty.

California LightWorks SolarXtreme 500

California LightWorks SolarXtreme 500

The California LightWorks SolarXtreme 500 is a full-spectrum white light LED grow light that has driverless COBs for LEDs. It pulls 400 watts from the wall and as a PPFD of 500 micromoles per square meter per second from 24 inches (0.61 meters) away, and 800 micromoles per square meter per second from 18 inches (45.72 cm) away. This LED grow light was designed specifically for grow tents and small-scale home growing. It uses new direct AC drive technology, which means there is no need for an LED driver.
