What bin Luxeon was in your Costco 2AA?

Out of 5, I had:
QXOL (looked good before I sold it.)
QYAK (Purply tint before I unloaded it.)
QV1H (looks good, it stays!)
QV1J (looks like cat pee. )
PYAJ (dim, but nice and hid white)

Newbie question here:

Where do you see the Bin? I disassembled the head and saw nothing. Do I have to de-solder the LED?

All the LEDs from my costco lights have either been destroyed /ubbthreads/images/graemlins/evilgrin07.gif, sold to friends or used. Out of 8 costco lights 2 had P bins, 5 had Q bins, and one had an R bin led in it /ubbthreads/images/graemlins/happy14.gif. I had a junk pop light thing that I stuck a lump of aluminum (scrap from something I pulled apart) in and mounted the R bin to it, works great now and is much brighter and whiter. All my costco lights either have colored luxeons or T bin lux III in them. Sorry I don't remember the rest of the bin, just the starting letters.

The bin is on the back of the star.
