Wow, some instruction even for me. I thought the LuxV was a quad die LED similar to the MC-E and P7. Instruction around every corner.
Hi, The Lux V is / was the first quad die package that I am aware of. It was also the first package to break the 200 lumen (rated) barrier. It is still the only package that contained 4 die that were carefully matched for Vf and output to each other. The market price was aroud $ 50 / each for those at one time. Compare that to a 200 lumen Rebel single die pacakge from the same company for a few dollars today. That is why I laugh when people complain about blowing LEDs now.
The Lux 1 is really the pacakge that started off the wide spread use of LEDs in flashlights, followed by the Lux III, which I consider sort of an enhancement of the Lux I.
Virtually all of the Philips Lumileds power LED products use 1x1mm2 die, just different generations and sorting of them.
Cree introduced their power led products a few years later, taking about 2 years to become competitive in efficiency and output. I have some of those early ones and and the difference between those and the Lux I was pretty visually obvious, even to the casual observer.
It has been interesting to watch the power led guys drive the technology and market forward.
