Identify Lux emitters?

[korpx]

Howdy, I'm going slightly off topic here, but I've just started shopping for my first Luxeon and I am trying to understand the bin codes.

It had me confused for awhile, but is it correct that the bin code is printed on the back and has no actual relation to the model number (eg I can't tell by the lambertian model number XHL-BW01 what binning it is)? /ubbthreads/images/graemlins/ooo.gif

korpx, when you buy the start, there will be something printed on the back. Just read the first few character on the first line (4 characters tops)

the XHL-BW01 prolly means lux3, star, lambertian. (i believe BW01 stands for lambertian, while XHL stands for lux3 star) /ubbthreads/images/graemlins/icon3.gif

It is others, such as you, who have adopted the practice of referring to the Luxeon III product as the "3W" Luxeon" That's very true. Thanks for pointing it out. Maby if I am concious enough, I'll type LuxIII instead of 3W. I however, still think it is a new and improved LuxI(?) LED and should have been given a name to suit.

Thank you.

Yep, LIII and LV stars should be electrically isolated just like an emitter should be.
