I was Away when the Cree LED hit.

I came back into the scene in January after about a year away from the board, Clueless to the revolution!

is there a FAQ or threads talking about:

Cree's binning?

P4 VS P3

Fv?

current rating

and how to test for these specs on an individual LED?

what was the predecessors to the XRE and 7090 etc?

WTH was the Luxeon K2?

I did some searching but little info was found except info eluded too but the info was not found!!!

noone has ever seen Q2 and Q3 till today :(
very efficient, very low temperature (compared to Lux)
thighter beam --> special optics / reflectors required
reflections from this metal holdig ring --> beam not this nice

"same" as SSC, but these are more or less equal in sizes to luxeons and can use "normal" focusing devices...
