HLG 600 R-Spec LED by Horticulture Lighting Group Review

Can the Horticulture Lighting Group’s HLG 600 R-Spec outperform 1000-watt Metal Halide (MH) or High-Pressure Sodium (HPS) lights?

This question refers to the bold statement that the company made about the power of the HLG 600 R-Spec. While LED grow lights do have their advantages, there is still something that MH or HPS lights can do that LEDs cannot. That is why it is worth checking if the claims for the HLG 600 R-Spec hold.



What You Need To Know About the HLG 600 R-Spec

The HLG 600 R-Spec Is A Full Spectrum Led Grow Light

Compared to its predecessors, the HLG 600 can work in the vegging and blooming stages of growth.

The HLG 600 R-Spec is also compact, and measures only three (3) inches thick, and has a length and width of 26 and 22 inches, respectively.


The HLG 600 R-Spec Uses Samsung LM301H Chips

The HLG 600 R-Spec uses Samsung LM301H chips, one of the more efficient components you can find in LED grow lights. The previous version used LM 561 C diodes.

In total, there are 1,152 diodes on-board, divided into four (4) quantum boards with 282 diodes each. That ensures an equal distribution of light across the footprint of the HLG 600 R-Spec.

The HLG 600 R-Spec employs an active cooling system, and its casing serves as a giant heatsink. Given this combination, you can say this fixture has a quite powerful heat management method, as it covers all bases.




Our Thoughts on the HLG 550 V2 R-Spec

The HLG 600 R-Spec features an accurate 3000K spectrum that makes it ideal for seedling to harvest. Because of its accurate spectrum, you can get larger yields.

And just the same, the 4000K veg tuned version of the HLG 600 R-Spec is just as exceptional. Users have noted that it has improved the quality of their yields when they shifted to the HLG 600 R-Spec.

For its footprint, the HLG 600 R-Spec has a 6 x 6 feet vegetative footprint and 4 x 4 feet for blooming, but you can push it to 5 x 5 feet grow areas. If you are a medium-scale grower, this light fixture will work for you.

Speaking of size, the HLG 600 R-Spec has a mounting height of three (3) feet for vegetative and 24 feet for flowering. That means you can save on space and use grow tents with lower headroom, as compared to MH and HPS, which need a few inches more, at the very least.

When it comes to energy consumption, the HLG 600 R-Spec only consumes 480 watts of power. At that rate alone, the HLG 600 R-Spec already leads versus 1000-watt HPS or MH lamps.

The HLG 600 R-Spec also has a power efficacy of 2.5 microns per joule. The previous version, meanwhile, was rated at 2.3. Now, this rating makes the HLG 600 R-Spec exceptional, considering the PAR standard of grow lights is at 2.0. That means you get an efficient lighting fixture without having to spend a lot for its upkeep.


When compared to the PAR ratings of HPS or MH lights, the HLG 600 R-Spec is way more efficient, which tells a lot about its ability to replace existing 1,000-watt non-LED fixtures. The move up to 2.5 tells a lot about the Horticulture Lighting Group. The company does not settle for less and pushes to improve existing product designs.




Is the HLG 600 R-Spec at par with 1,000-watt HPS or MH lights? Definitely, yes. Its features surpass the traditional 1,000-watt HPS and MH lamps traditionally used by growers.

The HLG 600 R-Spec provides a lower upkeep in the long run, and its lights don’t degrade like HPS or MH lamps. If you are thinking of upgrading, or looking for a larger lighting fixture, don’t hesitate to invest in the HLG 600 R-Spec.
