DIY LED strip builds have become very popular recently. The mid-power section of our forum is full of threads created by DIYers looking to build their own custom lights, and new builds and ideas are surfacing every day. If you don’t live somewhere where you have easy access to premade lights like HLG Quantum Boards or ChilLED lights, you can save a lot of money on customs, duties, and shipping fees by piecing together your own lights using the same diodes as these guys do. That being said, building these lights does require a fair amount of work, and if you’re new to the game and can afford to buy a premade light from a reputable company like those listed above, we’ll usually recommend going that route first to get your feet wet. However, if the cost is prohibitive or you’d prefer to roll up your sleeves and build one yourself, you’ve come to the right place.
Part 2 of this series examines constant voltage models and parallel wiring, as well as thermal runaway and series-parallel wiring.
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.
I’ve been working on a little experiment lately.
I’ve got got 3 little 2’x2′ spaces set up in the basement, and each of them has a single Quantum Board in it. The first space on the left is a 4000K 80 CRI board, the second in the middle is a 3000K 80 CRI board, and the third is a 3000K 90 CRI board. Each of the 3 spaces has 4 jalapeno plants in it from the same pack of seeds, and I’m feeding all 12 plants the same amount of nutrients from the same batch, at the same time. All 3 boards are getting the same amount of power and are hung at the same height.
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.
