The Mean Well HLG line is the undisputed king of drivers in the DIY LED grow light world. The goal for this series of videos is to provide a complete breakdown of everything you need to know about them, whether you’re totally new to DIY LED, or a seasoned vet. We’ll be covering:
Part 1 of this series provides an overview on the different types of drivers within the HLG line and focuses on constant current models and series wiring.
We’ve officially hit the 1 year mark and what better way to celebrate than giving something away? Up for grabs is a brand new Horticulture Lighting Group HLG 65 light, which is great for vegging up to a 2’x2′ space. Just log in to the gleam app below and follow the instructions to enter. The giveaway is open to anyone 21 and older in the USA and Canada (excluding Quebec). The rest of the terms and conditions are visible in the bottom-left of the box below.
It can be a pain in the ass having to sort through a bunch of data sheets to find what you’re looking for, so I’ve compiled all the relevant specs for Mean Well Constant Current and Constant Voltage HLG series drivers into a couple spread sheets. I’ve also pulled data from their test reports – you’ll see info from the specification sheet marked “SPEC” and then info from Mean Well’s testing, marked “REPORT”. You’ll notice that usually these drivers are capable of doing a little more than they’re rated for, however this is often for the “A” type driver, on which you are able to adjust the voltage or current higher than you can on the “B” type.
From Instagram live: Taking another run at overpowering a QB288, this time with an HLG-600H-54 and a boost converter. Sorry for the crappy quality and vertical video – the format it saves to isn’t great for watching on PC.
In this video, we assemble a Horticulture Lighting Group HLG 550 from individual components and then test it out.
This video covers the results of an experiment I did in order to determine how much power it’d take to destroy an HLG QB288 and QB304 Quantum Board. I was pretty damn surprised!
I returned home this week after a stint of working out of town and came back to some really cool new gear waiting for me, courtesy of Robin at Horticulture Lighting Group. There’s so much that I want to get done, but the first piece I was eager to experiment with was their Slate 3 Triple heat sink. You can check out my video review below, or continue reading and I’ll hit all the important points in text form for those of you who brought your phone to the bathroom and don’t want anyone to overhear you watching grow light videos while you’re in there.
In this second video, we’ll go over how to dim each of the QB kits, then take a closer look at the LM561C, and how the Quantum Boards are physically laid out. We’ll also cover wiring the boards in series and parallel, and look at how to properly match QBs with drivers so you can expand your kit or upgrade your driver. The next and final video in the review will review PPFD results from each of the kits and go over some final thoughts after using them.
This video documents my assembly of the 90 watt, 135 watt, and 260 watt versions of Horticulture Lighting Group’s Quantum Board kits. In next week’s video, we’ll look into how the boards work, how to dim them properly, and how to expand your light with additional boards. Shoutout to HLG for sending me these kits to experiment with!
