what is the most efficient DIY LED build today?

Not LED but I think nuclear fusion may be the best. You only have to get hydrogen atoms to combine and form helium, I believe a byproduct should be plenty of light to turn whole continents into grows.

It seems like the best commercial lights you can get nowdays perform the same as the DIY stuff we built @ 2015-2016
Cree CXB 3590 at 700ma was producing 64% efficiency or 2.95 umol/j
with cooler Kelvin temps (good for veg) and high bin you could get even higher efficiency
Chilled puts those crees in a lightsphere and the real numbers are quite a bite lower. All those numbers are from the spreadsheets that where based on datasheets. Which werent completely correct. The test reports are on on Chilleds webpage. And Cobkits here on the forum ran a lot of tests in his thread showing cree as coming in behind lower speced cobs.

I've never seen an atomizer that could handle that kind of power. I've had 120w coils and anything over 100w was too hot. If you're wiring up your own coils, god damn. That seems like a steam cannon that would cook every part of you respiratory system while charging up a hand grenade that you're holding up to your face.
You clearly don’t know how to vape bro.

Good to know you are still around RS. I believe it has been shown that both grow light and diode manufacturers have published some rather optimistic Data. It's interesting how the efficacy of grow lights has been creeping up.... when they are using the same LM301 diodes! :roll:

Do you have any opinion of the testing Migro does? Not precise accuracy, but just as a useful comparison?

I like all and any testing. Migros approach is good, it gives you the end result of spread, watts and efficiency.
However, he uses a tent type space for measuring mostly which might muddy data for a larger openspace with multiple fixures.
In the end though, for that testing/growing youtube stuff there is noone like Growmau5 of yesteryear. #MGM5GA ;):p
