Very cool to see this on the front page - Don's "The Most Efficient LEDs!" site at https://donklipstein.com/led.html is a great resource, since it is very hard to come by reliable information on early commercial devices!
We used some of this data to trace progress in LED development for our recent Nature Energy paper on technology spillovers in solid-state lighting: https://doi.org/g9kcjd.
