I was looking at some LED car light bulbs online (for a backup light application (personal vehicle) that takes a stock 921 bulb), and ran across a product with a "2020" SMD (surface mount) LED in it. I often take a look at LED specifications to see if the output claimed for a light or bulb is even possible, but in this case I could not find anything that seemed definitive, online. Most was confusing...

...Such as references to "2020 (5050 Metric)" LEDS, and various references to multicolor (RGB) LEDs (which are a different animal entirely.

Looking at the product drawing, the physical size of the LED being 2mm x 2mm seems reasonable.

But, if the seller's rating for the light is even halfway reasonable, and this seller doesn't usually seem to be in total exaggeration mode / the reviews seem pretty good -- the LED mfgr. is getting in the neighborhood of 100 lumens out of a 2mm x 2 mm LED. That's a LOT. Possibly it could be done with the latest chip materials and very good heat sinking?

I would think this would be a killer LED chip for a tight-focus beam flashlight.

Does anyone have a good source of info. or spec sheet on this LED?

Just be grateful it’s not this new LED you bought into.

ITU Specs for REC 2020

It is unlikely that this is the case, but (in a past life) we worked on expanding the cinema color gamut from REC 709 to a new standard called REC 2020 (BT2020).

Since these LED lights can be used for multiple purposes, and REC 2020 hasn't really taken off, perhaps the factory designed the LEDs to meet REC 2020 specifications, and somebody bought them for another application already stamped "2020" at the factory, maybe part of the plastic mold for the body.

Of course, just as with Made in China "organic" products, do not believe that they meet the actual standards as the US and EU defines it. These could be ones that didn't meet the tests for REC 2020, but who would care if used in another application ...

Great. You can use them to blind everyone behind you.

A 2020 package (5050 metric) is approximately 0.2 inch square (5.0 mm square). I found some Cree LEDs of that size on Mouser that looked even brighter than the ones on this package. The Cree ones had 4 LED dies on each package which can be wired in parallel or series.
