This is clearly an old process - when was the last time you saw a 7-segment display, or those big red round thru-hole LEDs, outside of hobby electronics?

I'd be very curious to see how this process differs from the high-power lighting LED manufacturing process (e.g. CREE), which is a more modern technology by several decades. I would guess there is much more of the automation people are expecting...

Every HP common slot server PSU has one of those round through hole LEDs on it. I have an HP server sitting here (DL580) that has two 7 segment displays on its motherboard. These things are definitely still used in modern products.

I can see 15 from here: TV, Babyphone (3) and Playstation controller (4), wife's laptop (6) and my mac charger (1).

Remember folks, there is a world outside of Silicon Valley.

At work yesterday, at a microwave communications equipment manufacturer. Through-hole LEDs are the easiest kind to mount on the front panel of rack mount equipment. And there are 7-segment displays on two of our adjustable power supplies.
