Well look at this....Ultrafire Lego

That's a WF-502D body on a Romisen RC4. The 502D bezel also fits onto the Romi's body. I had to use a small copper spacer to fill in the gap.

Thanks. Jerry from KD told me the heads weren't interchangeable, but I see that you've left the neck on the WF502. If the head of the Romisen RC4 is the same as that of the WF500, then I should be able to do what you've done. I own a few WF502s and I can get the WF500 neck and bezel from lighthound for half of what it costs to buy a whole WF500 elsewhere. I already have 52mm glass lenses and a few WF500 drop-ins from Mag modding so if all goes well, I can upgrade the 502 to the 500 head pretty easily. My goal is to eventually run the DX P7 drop-in on the WF502c with 2x18500.

WF500 head came in last night in matte black finish. The appearance was a perfect match for the 502c I intended to use it with. After unscrewing the bezel from the 502c, I just could not get the WF500 head to thread onto the 502C head properly.

I turned to my 502b, which has a glossy finish and the WF500 head screwed onto the WF502b head perfectly, which is really wierd, because so far, the 502b and 502c heads, bezels, bodies tailcaps have all been interchangeable. I tried using a dremel to sand down the threads just a tiny bit on the both parts and I can only manage about half a turn with the finish-matched parts.

There must be a microscopic difference in the TPI of the two 502 series lights I have, that's just small enough to allow the 502b work with the higher TPI 502c and the lower TPI 500, but doesn't allow the 502c to work directly with the 500.

If only the finish on all three lights matched! It's a shame too, because the extra length added by the 502 head makes the battery config I had planned actually work better for the color-mismatched 502b.

Stuff like this drives me crazy! :crazy:

Here's a crazy question. Can the wf500 head fit on a surefire 6p as a turbohead? The reason I ask is because I have a 502b, 6p, and g2. The 502b outer most bezel threads right on to my surefires.

Little hijacking here......does anybody know if the WF-500 head would fit onto a G&P Scorpion body? I recently got a LED dropin (3xSSC) for the WF-500 that unfortunatelly does not fit my Scorpion.

Thanks
Eric

if anyone else has both the wf500 and a 6p, i am curious if yours fit together. because my examples of both lights definately don't thread together. my wf500's head is slightly larger than my 6p's neck. unless my wf500 fell victim to ultrafire's variances in production. not the first time this has happened. (i don't have a wf502 to test fit)
