What Legoes with What?

My new BLF A6 legoes with the UF-2100. The uf-2100 tailcap works on the A6 tube and head but I can't get the A6 head to light up on the uf-2100 tube/tailcap.

I have successfully legoed the black and silver Ultrafire 504b and Uniquefire L2 heads, bodies and switches with the whole Solarforce lineup. I don’t have them myself, but the Spiderfire stainless steel P60 hosts should also lego well.

Thorfire VG15 battery tube and switch fits Blf X6 Se

from a search, happened to notice a couple of mentions in other threads:

Nitecore P12 body using Nitecore EA11 head

Mentioned by antenne, elsewhere:

roche f-12 has a shelf for 20mm triples

they used to say the olight i3 AAA head fit the streamlight micro stream .

olight black clips from illumination supplys garage sale fits the z8 stainless zoomie (junk) and the original Mr lite blf light yeAA

Xeno diffuser TWSE v1 with the flat top fits eagletac d25a ti lights(i assume that all D25a's are the same size ) and is an amazingly nice diffuser.

I just saw a “read somewhere” note that the MtnElectronics spacers (2 different ones) for the S2 and S2+ may also fit some other lights.
Anyone know for sure?

The A6 BLF clip fits the original Convoy M1 very well. Will post a picture later.

The clip for the Roche F6 fits the Convoy S2+ really well (even better than on the F6) and it is super sturdy. However it is not a deep carry and I don’t know where these can be bought separately.

Mini-01 battery tube threads into a p60 reflector.

The 18650 Thorfire C8 body and tailcap match well with the head of the 18350 Nitecore EC11.

Other C8’s that do NOT fit the EC11:

…………… Convoy 8 …………………………… Generic “CREE” C8

Tailcaps: the tailcap of my red Convoy S2+ fits and works correctly on the battery tubes for both an Eagle Eye BLF-X6-SE and an Manker A6. (only checked one of each)

The tailcaps for both of those black lights are too tight — they start but won’t screw onto the red Convoy S2+ battery tube.

As noted above — the tolerance for variation is so large on these that a sample of one isn’t proof of any general claim about what fits what.

I’d guess somewhere there are three bins — heads, body tubes, and tailcaps — and whoever assembles the lights just keeps fishing until he finds a complete set and calls it good.

It’s the Goldilocks approach to flashlight construction. Some are too small, some are too large, some are just right.

That’s an oversimplification — threads have to be defined by several different numbers — spacing, depth, slope of the cut, maybe more. We don’t get that kind of precision.
(Or we get the seconds, if there are some that good)


Has anyone checked the threads for the retaining rings? I don’t know if those are done to any standard or not.

Could the metal switch of the red Convoy S2 take the high draw of the BLF A6 do you think?

BLF A6 pocket clip is a nice snug fit for Imalent DM21.

My Convoy red S2+ tailcap legoes with the Jaxman UV tube, and vice versa.

(that as noted above isn’t always the case, and your tailcaps may vary — but these could be twins as far as the threads and depth go.

Conformation here with the two lights I used.
S2+ tailcap fits on A6 body but not the other way around.
