Correct me if I am wrong--
Luxeon is a newly developed LED, produced by Lumileds.
There are three types that you will see often on CPF--
Lux I(~25 lumens), Lux III(~60-80lumens), Lux V(up to 120 lumens).
For more details, I would suggest reading up at
Lumileds page. /ubbthreads/images/graemlins/smile.gif
