Would I be correct to say that this Luxeon III star from a Princeton Tec Eos is an RX0K? Please advise.

You are absolutely correct 
Oh yeah, not right about it being a lux III

I like the pic; if you went back in time, say 20 years, and told someone the printed circuit was for a miniature flashlight, they would probably laugh at you.

My bad. I actually thought the Eos had a Lux III. Thank you, all.

I don't know about the electronics of the EOS, but sometimes with shallower reflectors intended for fairly close up work, the line is blurred between Lux Is and Lux IIIs... THe RYAK in my Dorcy 3D Super 1W seems just as bright as a direct drive 3W TV1L or TV1K until you start trying to light up distances past 50 or 60 yards.

Thats an excellent bin, R is very bright and X0 is as white as it gets. K is a bit higher than many would prefer, but is still a very respectable forward voltage. You have yourself a winner.
it´s a MW1D so luxeon 1

From looking at the bin code chart, old and new, wouldn't WO be whiter? They are close to each other on the chart, but where the line goes through for the older coding system seems to also suggest that the WO is whiter, being in the old 3 code (white), and XO being in the 4 (bluish).

That regulator circuit looks like it has a thermistor in contact with the heat sink - meaning it probably has some kind of thermal protection and/or temperature-controlled regulation on board. Props to PT for that.

Hmmm... My EOS has a PX1H star. Not as white or bright as I'd like (it seems dimmer now that I replaced the optic with a reflector, because the beam is spread out wider I guess). I've been meaning to swap in a TWOH star. That should make it a little brighter and whiter without affecting the runtime, right?

In my experience X0 is the whitest. A few may have a slight blue tint to them, but that is preferable to the pinkish tint I've found in some W0's. X0 is also the smallest bin so the LED's should be fairly uniform. LED's that fall to the X0 side of the X0/W0 border should be as perfect as you can get.
