This appears to be the manufacturer page for this LED:

https://store.yujiintl.com/products/yujileds-bc-series-high-cri-cob-led-900=
h-1500w-pack-1pcs

It has a forward voltage of between 30 and 41V which means that it must be
an array of LEDs. As such, I'm not sure what is meant by "world's brightest
single-unit LED". I find it hard to believe that nobody makes a more
powerful single module (containing multiple LED junctions) especially since
this company is one I've never heard of before and is not in the top ten
global manufacturers of either LED dies, LED modules, or LED lighting
assemblies.

Also, the manufacturer itself links to this guy's video on the page for
this LED :)
