The Ultimate Horticulture Lighting Group HLG 550 V2 Review
Are you looking for a grow light that has high-efficient white light quantum boards with a great canopy penetration, as well as, a grow light that is best and ideal for your plants from seedling to harvest? Well, your search is finally over! Because Horticulture Lighting Group HLG 550 V2 is the grow light you’re dreaming of!

HLG550 V2 is a Commercial Indoor Horticulture LED grow light which was introduced to the market in May 2018. This light is an efficiency upgrade from the HL g550 V1 and it’s designed to replace a single-ended 1000watt HID.

To give you some details about the differences of the HL g550 V1 and V2, you need to know: V2 contains Samsung LM 301 B diodes while V1 uses LM 561 C diodes. Overall, the V2 draws around 30 fewer watts and exudes more light from 2.3 micromoles per Joule to an incredibly 2.5 microns per Joule.

If you’re really curious about this grow light, then better read this teaser that we prepared only for you! When you already have this light on-hand, you can immediately see a sturdy foam that's inserted around the light and it’s protected with some plastic.

In addition, you can also see that it comes with free four hangers and this fixture measures 26 inches by 20 inches by 3 inches and it weighs about 18 pounds. A large Dimmable mean well HLG-480-C2100A DRIVER sits on top of the light and powers a quantum boards on the bottom of the fixture. Moreover, the rest of the fixture is a thick aluminum heatsink and it’s an Anodized Aluminum Heatsink that’s passively-cooled without cooling fans. Meanwhile, the power cord and plug of the light is available in 120 volts and 240 volt U.S. plugs and 202 for European or Australian outlets.



If you’re not still convinced about the power and capability of this light then, you must read below the Top 7 reasons why you should get one Horticulture Lighting Group HLG 550 V2 grow light:

It is a 1000 WATT MH/HPS Replacement


HLG g550 v2 is considered to be the HLG's flagship LED grow light because it’s designed to be using groves requiring high-intensity lighting. Thus, making this light a replacement of a 1000 watt single ended metal halide or HPs grow light.

V2 has a lower power draw than V1 because it draws around 480 watts at the wall while V1 threw about 510 watts at the wall that’s about 6 percent fewer watts with about 2 percent higher light output. In short, there’s about a 9% increase in power efficacy.

It has 1, 152 TOP BIN SAMSUNG LM 301B Chips 


Did you know that the HLG 550 V2 has 1152 Samsung LM 301 B diodes across the entire fixture? Of course yes! Because the fixture’s quantum board are made by Samsung and each contained 288 diodes and these diodes are considered to be top flux bin and top voltage bin.

It has a PAR EFFICACY of 2.5 UMOL/J


HLG 550 V2 has a power efficacy that is staggering to 2.5 microns per Joule. This is an amazing feature! Why? Because anything that’s above 2.0 micromoles per Joule is considered efficient and mostly a standard for LED grow lights nowadays. Thus, 2.5 micromoles per Joule is really going to the next level of the white diode technology today.

It has a PPF of 1, 178 UMOL/S


To make you feel secure, the PPF output of this light was measured by a reliable and competent third-party laboratory to be around at 1178 micromoles per Joule. You can actually check the link to see it for yourself by reading the Independent Lab test report we included there. Meanwhile, if you want to know the lumen output of this light it has an 80, 833 LUMENS and it’s rated for 110 to 240 volts as it draws about 480 watts at the wall.

It has a 3000K SPECTRUM “perfect from seedling to harvest”


HLG 550 v2 is a white full-spectrum with 3000K which is the most popular option among growers because it’s ideal for a seedling to harvest growth. Another reason is that it’s best for larger yields.
Meanwhile, the other option is the 4000K this one is considered to be best for veg, but can be also used for the seed to harvest as well, most growers choose this if their main goal is to increase quality. Other options include 27000K and 5000K versions that are also available on demand today.

If you're confused about the term “white light” and always wondering what really is it then, take note of this: The white light spectrum allows you in your working environment to be able to see the plant’s natural colors. The spectrum contains a medium amount of blue peaking at about 455 nanometers and on the other hand, has a large bump in orange-red peaking at about 605 nanometers.

Take note: There’s no UV in the spectrum.

It has a COVERAGE AREA of 6’x 6’ for veg and 4’x4’ to 5’ x 5’ for flower


The vegetative footprint for this light is about 6 ft. by 6 ft. area. Moreover, the flower footprint is recommended up to a 4.5 ft. by 4.5 ft. area. This fixture has a solid 4x4 area, but you can still use it up to a 5 by 5 ft. space.


It has a MOUNTING HEIGHT of 36” for veg and 24” for flower


This grow light’s hanging distance for veg is about 36 inches or if you like you might want in hanging it closer and dimming down the light to 50% intensity. Meanwhile, the flower hanging height is recommended at around 24 inches and this is considered to be the best distance for highest intensity while maximizing uniformity.

This light I cannot say enough about. All of the Growers that hate on LED lighting have not experienced this grow light yet. The crew at Horticulture Lighting Group have taken LEDs to the next level. Not to mention the design and Sleek look of this light. So to the crew at Horticulture Lighting Group thank you for making a quality product. I cannot wait to see what you guys come up with next! ★★★★★ 5/5
