    Back in the 90's, a friend of mine purchased a new stereo receiver that had a blue LED power indicator light instead of the standard red. The envy of everyone who saw it. Thanks, Shuji!

      It’s humbling to think that the fundamentals of LED light bulbs all came from one determined inventor who bucked conventional wisdom and stuck with GaN for LEDs. Thank you Prof. Dr. Nakamura-sensei.
