The New HLG Grow Lights: Classic Designs Made Better

They say if ain’t broke, don’t fix it. Recently, Horticulture Lighting Group (HLG) took a different approach to this saying: if it ain’t broke, then improve it, precisely what they did with their newest releases. HLG recently came up with updates to their best-selling grow lights. Let’s look at how they’ve changed things for the better. 


HLG Scorpion Diablo 

HLG Scorpion Diablo Full Spectrum LED Grow Light

The  HLG Scorpion Diablo is a spider grow light that uses six sets of quantum boards to deliver even light distribution for grow tents and even vertical racking. Previously, the Scorpion Diablo ran up to 650 watts. This redesign allows the new Scorpion Diablo to run up to 750 watts. You can also hang the Scorpion Diablo at 15 inches from the previous 18 inches, which makes it ideal for tight growing spaces. 

The new Scorpion Diablo has an anodized aluminum heatsink that is slightly thinner and lighter than the previous version. The efficacy and output are lower and consume more power than its previous version. Still, with the help of the new reflectors, the new Scorpion Diablo can redirect more light onto the canopy than in the past design.  The Scorpion Diablo works in grow spaces of up to 6 x 6 feet and is Grow Flux Compatible. 


HLG Scorpion Diablo X

The  Scorpion Diablo X is the new flagship model from HLG. Like the Scorpion Diablo, the new Scorpion Diablo X also features a lighter anodized aluminum construction with angled reflectors that improve light distribution on the canopy. 

Unlike its previous version, the Scorpion Diablo X uses up to 715 watts of power, rated at 650 watts. Efficacy and output are also slightly lower, but like the new Scorpion Diablo, this grow light is still better with the redesign. 

HLG improved the design of this model by incorporating the QB54A boards on the Scorpion Diablo, and it also comes loaded with the newer Samsung LM301B and LM301A Evo LEDs. This grow light also has Samsung V4 or Osram V5 reds. The added red LEDs can improve photon efficiency. 

The Scorpion Diablo X may be hung 15 inches from the canopy and can cover up to 6 x 6 feet grow spaces. It is also Grow Flux compatible. 


HLG 750 Diablo

The  HLG 750 Diablo is a scaled-down version of the Scorpion Diablo, as it sports only four quantum boards. And, like the Scorpion Diablo, the 750 Diablo also gets a new design in its construction. 

The HLG 750 Diablo was designed to hang over grow spaces of up to 6 x 6 feet. The 750 Diablo can provide more lighting over the canopy with the new angled reflectors, unlike its predecessors from the same brand. And thanks to the reflector design, this grow light may be placed at a lower height, making it ideal for vertical racking applications. 

The 750 Diablo features an efficacy of 2.88 umol/J and an output of 2056 PPF. You can also connect this grow light via Grow Flux. 


HLG Scorpion Rspec Far Red 

HLG Scorpion R SPEC Far Red Full Spectrum LED Grow Light

The  Scorpion Rspec Far Red is another improved grow light from HLG. Like the other new releases, this grow light sports the same angled reflectors that improve light distribution. This grow light uses six sets of QB272 Quantum Boards and is loaded with 660nm deep red and 730nm far-red spectrum LEDs that give it that extra red spectrum. And like its previous version, this grow light does wonders in the early stages of plant growth. But just the same, the new Scorpion Rspec FR is also full-spectrum. 

The Scorpion Rspec FR can cover a 5 x 5 feet footprint and uses up to 715 watts of power. It also comes with the option for Grow Flux connectivity.  


Growflux Access Point Controller

One common denominator with these new grow lights is the Growflux compatibility. The Grow Flux is an access point that lets you control your grow lights over an Ethernet network. It can connect up to 1,000 grow lights. Using the Grow Flux is safe since it uses AES128 encryption. Setting up the Growflux is relatively straightforward. It works with most firewall connections and should allow setting up the Grow Flux with your HLG Grow Lights. 



These redesigns are proof that HLG doesn’t just rest on its laurels. By introducing new features to existing models, HLG commits to its users to continue providing high-quality products. What’s even interesting to note is how they opted to integrate these innovations into an existing product and not market it as a new product. Now, these upgrades would look minor, but truth be told, these upgrades make a big difference in your plant’s growth. That said, these innovations are a welcome upgrade. If you’re looking to switch from the legacy versions, it will make a big difference if you do.
