what is the most efficient DIY LED build today?

Herbal_Essence said:
that's nice but we are looking for a DIY solution that can make those numbers higher
within a reasonable price range of course
but even x2 or x3 the market price is acceptable if the increase in efficiency is at least ~20%

It's easy, invent better diodes.

Or use 3x more of them, might gain 20%. YMMV.

that's what we did with the CXB3590 COBs, we used more of them and also drove them at a much lower current than rated
they were rated for 140 watts and we drove them at 25 watts making it 2.95 umol/j
but all those numbers are from smart people in this forum that did all those calculations

has anyone measured the exact increase in efficiency at least in theory?

or you just say it's easy but don't have the answers?

Countless scientists, engineers and potheads, along with every diode manufacturer. It's usually in diode datasheets.

It is easy. Measure power in, light out and do the math.

I like how on top of trying to extort his employer, he then starts a company with a single letter switch.
If that is any indication of his character, his efficiency numbers probably follow the same business plan

Third party testing. The rest is silly drama that I could care less about. HLG screwed up by never making bar lights. GML was the head designer.
 
let’s see who is around in 1-5 years in led game, my guess gml is gone and hlg is still around. It was interesting when gml first was part of hlg , shoot whole time Lol, he if anything admitted he barely knew shit about led’s or lights . What his now ”grand master”. That name sours me too lol

i personally like the hlg 150-200 watt, heavy duty heat sink, 10+ Ft durable built in cord, detachable ballast. If I was redoing my whole room it would be cool instead of every 650r have 3-4 150-200’s. I realize the more connections to Ur power too


very durable and already assembled, being under a buck per watt . So many pro’s

I'm not sure if you understand how keeping a job works. And then he started his own company and had everything verified third party.

I agree with this. It's definitely a cringe handle.
 
Efficiency is cool but in my opinion it’s muddying the water as far as led progression goes.

how many of you are running hella efficient lights and then throwing in supplemental UV or far reds? HLG won’t even fuck with adding Uv to the fixture because their efficiency would tank.

they know we want efficient lights and we also want these boutique spectrums. Puts them in a bad position.

You sure GML was a designer? I thought that he was just the Canada rep. I agree that HLG missed the boat not making bar lights. I think they had so much invested in board design manufacturing that they simply refused to jump ship, as they still needed to recoup on their original investment.

I could be wrong, but I'm pretty sure I heard him say that he designed the Scorpion.
