Horticulture Lighting Group HLG 550 V2 RSpec Indoor Full-Spectrum Quantum Board LED Grow Light

The HLG 550 V2 RSpec by Horticulture Lighting Group is a design upgrade of the 3000k HLG 550 V2, which is now discontinued. The spectrum of the RSpec version is 3500k whereas the HLG 550 V2 is offered at 4000k. There’s a little bit extra blue light in the R-Spec diodes. The additional blue spectrum helps mostly during vegetation but it’s also absorbed during flowering. This quantum board LED grow light still utilizes 1,152 LEDs (1088 of which are the top-bin Samsung LM301B LEDs), but HLG swapped in 64 Osram 660nm deep red diodes, spread out evenly among the four circuit boards. These diodes increase the electrical efficiency and the overall light spectrum. The extra red intensity also contributes to faster growth during the bloom stage. The HLG 550 V2 RSpec Full-Spectrum Quantum Board LED Grow Light is ideal for all growth phases – seedling through harvest.

The additional Osram LEDs add a 660 nm deep red light give plants a huge boost during the bloom stage. It results in bigger and more potent yields. The light emitted by the HLG 550 V2 RSpec is ideal for full cycle plant growth and is especially powerful for flowering.

The HLG 550 V2 RSpec quantum board is a large, white full-spectrum, modern design LED grow light that effectively covers a 4.5 foot by 4.5 foot grow space. Horticulture Lighting Group actually came up with the “quantum board” grow light design and started the trend among the indoor plant growing community. Quantum board LED panels are now one of the most popular grow light choices among the experienced growers. It’s basically four custom designed full-spectrum high efficiency white light QB288 quantum board panels combined on one fixture. The biggest advantage of the Horticulture Lighting Group quantum boards are the quality components. Chief among them are the Samsung and Osram LEDs and the Meanwell drivers. These high quality components are extremely efficient, delivering a high output, while consuming less power and generating less heat than almost every other light on the market.

If you’re curious, or just switching over from an HPS grow light, Horticulture Lighting Group equates the HLG 550 V2 RSpec to a single-ended 1000 watt HID grow light, while it will draw only 480 watts from your wall at maximum power. The Meanwell driver has a rubber stopper on the “Output” side, you can remove the rubber stopper and adjust the light intensity with a Philips screw driver. You can dim the HLG 550 V2 RSpec down by 50%, bringing it down to 240 watts of power consumption, which makes this LED grow light even more efficient, when you don’t need the full output!

The HLG 550 V2 RSpec doesn’t feature cooling fans or heat sink on the design. That’s because it doesn’t need them. Many commercial growers reported their HLG 550 V2 RSpec gives off “barely any heat.” For many of them, an oscillating fan is enough to manage temperatures while using this quantum board LED grow light.

Output and Coverage Area

One major advantage of the Quantum Board LED grow lights is the uniform photosynthetic photon flux density (PPFD) that doesn’t fade dramatically when you measure further from the center of the PPFD chart, which is the case for many “regular” LED grow lights. To understand better, let’s look at PPFD charts for the HLG 550 V2 RSpec quantum board panels:

As you can see, the coverage is much more even than most LED grow lights. Instead of sky-high PPFD readings in the center of the footprint and minuscule readings in the corners, the difference is not nearly as pronounced. But of course there is still a difference. That is unavoidable. 

The reason for the even coverage is the size of the fixture. With a smaller fixture (like most competitors), light to the corners of the coverage area has to travel further, since it is coming from the center of the area. It loses much of its intensity by the time it reaches the canopy. With the larger HLG 550 V2 RSpec fixture, light does not have to travel nearly as far to reach the corners of the coverage area, since the large size of the fixture brings LED diodes much closer to the far corners. As a result, the light does not lose nearly as much of its intensity by the time it reaches the canopy.

HLG 550 V2 RSpec Main Features:

  • Draws only 480 watts from the wall — save over 50% on your electric bill over HID lights
  • Dimmable to 240 watts — save even more when you don’t need the full output
  • Unmatched output — PPF of 1257 μmol/s is an amazing output for only 480 watts of power consumption
  • Equivalent to a single-ended 1000 watt HID system — but costs far less to operate and generates far less heat, too
  • Perfect spectrum for plants — 3500K white light plus 660 nm deep red
  • 4.5 by 4.5 foot core coverage — with an even light spread, due to the diodes being spread out over the large fixture
  • QB-288 quantum boards — with Samsung LM301B 3500K white and Osram top-bin 660 nm deep red diodes
  • Meanwell driver — best driver on the market, dimmable to 50% intensity
  • 2.6 μmol/joule (and 168 Lm/W) — this fixture is one of the most efficient lights on the market
  • Daisy chain — connect several lights together and run them from a single outlet
