Is the WF-502B MC-E (BIN K) a huge mistake with 1 x 18650?

Hey all,

I have an order brewing at DX for a Ultrafire 502B that allegedly has the MC-E, bin-K. I am seeing different stuff that one 18650 cell may not really be the right kind of power for this particular emitter.

Is the the wrong 502B to get? I can still cancel my order and choose a better emitter for the 502B.

Input appreciated!

Most of the MCE lights at DX are K BINs. There are a couple M BINs, but I really dont think the different BINs make a significant difference from one host to the next. Far more important than the flux bin are the drive current, circuit efficiency, 18650 cell capabilities, and thermal design of the host. If all 4 are optimal and identical between 2 lights, then yes the flux BIN can make a difference.

It's the current that I am wondering about. is single 18650 enough to drive the MC-E bin-K emitter?
 
Probably not with the driver they give you. You're better off getting an XP-G - better efficiency, and the brightness probably won't be too much different.

The M bin that comes with the 501B from DX is the brightest of the quad die P60's I have by a long way.

The K bin ones are not worth it, the M bin one I received is.
 
I have the M bin MCE 502b, and it seems to be nearly as bright as my Aurora ak-p7-3. The MCE light has a huge donut hole though, and not as much throw as the p7-3. Warmish tinge as well. So far no problems - have taken it for a few walks, left it on high for around 15-30 mins.
