DIY LED Resource Thread: Recommendations, Ideas, Links, Tips, Tricks, Grows and More!

Working on DIY LEDs? Have skills which are useful for DIY electrical projects? Have a tutorial on an LED build? Please, link and share what you've found so others can do the same. I'll keep this post updated as the thread fills with the gems we've gleaned on LEDs.

I want to take a moment and thank all the members who have already contributed here. There is an amazing amount of information available, and all of you make it possible. This exchange of information is what drives progress in leaps and bounds. I, for one, greatly appreciate what you do.

Thank you so very much.

I've begun to add links I know of. Right now I'm just beginning my research. I've recently begun working on integrating more structure in my projects. Though I've been aware of my autism for some time, I've recently been made aware of how severely debilitating my ADHD is. Too late for this project, but I'm beginning to keep more detailed notes on my research. lol

Ultimately I would like to see builds for the more common sized flowering areas. Micro grows and also tents at 2x2, 4x4, 5x5 and 4x8. (Edit: I'm surprised there aren't more around, but I'll keep adding them slowly. Check back often. lol)

Suggestions on formatting are very welcome. A data dump of resources isn't much help if it's not very well organized.

Eric Harrington explains the current state of HID vs. LED lighting, as of the end of 2018

I found it very enlightening, especially how the new ceramic based chips have reduced the breakdown time significantly. These new chips take over a decade to lose 10% of their output. Unless HID makes some novel changes, I don't see them competing in the next few years at all.

Wondering about driver on board AC COB leds? (I did, I built a few) Don't bother! Migro tested them: https://www.youtube.com/watch?v=OnaVr2Cgspc Results after 3:25.

Blurple: 0.3 ppfd/watt
Warm white: 0.65 ppfd/watt

They're quite bright, but so is 50 watts of fluorescent and we all know how inferior it is. The leds I've tried all have a strong flicker that you can capture on camera, it gives me a headache if I witness the light.

Quality definitely differs from mfg to mfg with these. It'll be nice when I have the equipment to test all this stuff myself. Spectrum output also changes between mfgs.

They tend to do quite a bit better when kept cool, since they have a power limiting factor as the heat goes up. Water cooling does look promising for this, especially with micro-grow spaces. They really shine in small spaces.

^ Right. I have some more modern ones with solderless connectors which seem a bit better. But it's not a huge improvement. I've also watched the bigclive youtube videos on these with interest . They would be a dream come true: what more would you want than a $2 50w driver on board led? With a $10 cooler+fan that's $12 for 50 watts, nothing can really compete. 2 9v fans running in parallel at 6v will keep 2 of them super cool. But I don't have the balls to try them out because of the worryingly low efficiency reports. I too lack the gear to test things properly. I wish more people would test them; I almost can't believe the low ppfd from the purple one migro tested.
