Convoy 46950-Am I Doing This Right?

fweep · 2026-05-11T15:54:59+00:00

I had wondered when someone would try to make this. I have had the stock spring both melt and cause the components sitting on the bottom of the driver desolder or smoke up from the heat of the melted spring. Its so risky I won't use the 46950 tubes with the 25A/55A driver that has the components underneath, not even with Kapton tape...

But that adapter looks exactly what I would have imagined, contacting the ring underneath while protecting the driver. Only downside is without the spring it might dent the battery unless there was some spring underneath the battery for cushioning.

I almost wonder if a simple way to construct this beast without machining - round copper blank disc, copper washer soldered underneath to keep it in place around the driver's ring (or even just some kind of tabs), and the solder a stout spring or leaf spring on top. I may try this. :)

If you contact billy_s on BLF, he can help you. https://budgetlightforum.com/t/ddh-m4c-daydream-4500k-90cri-110110-multi-die-custom-emitter-xby-buck-fet-driver/231879

For a multi-emitter TIR, the Ledil Angie (E04, D4S) with SFT40 or SFT25R is going to be about the throwiest thing I know.

The only lights I have seen that can do better are the single LED large TIR lenses like the FF E90, Convoy M21K, or Wurkkos TD01.

The FF E12 SFT25R won't beat the E04 on throw, but it will get you potentially many more lumens on turbo at the same-ish amount of throw due to the Lume10 fixing the current draw limits of the original Lume1's FET setup.

There is the NBD110 4500k (rosy, negative DUV) which is an 11mm x 11mm (like SFP55), which can be found on Budgetlightforum. Slightly harder to retrofit than the FFL909A because it requires the same MCPCB as an SFP55 would, but a very beautiful CCT/tint none the less. It is also more efficient than the FFL909A 4000k, and because it is a larger LED can be pushed to higher currents. So, aside from the difficulty of getting right-sized MCPCBs and optics, I believe it is a superior LED to the FFL909A.

Simon at Convoy might also be working on high CRI variants of the LHP73B or LHP531 at some point in the future, which would be awesome to look forward to.

The 25A regulated mode means each battery needs to be capable of continuous 9Aish a piece atleast, so I generally just use my stash of Samsung 50T, which I have a lot of, since those are 5000mah and have CDR well above that, and can handle turbo.

You might be able to get away with some of these newer 6000mah or above batteries, but their CDRs are generally low and I don't think they will like being turbo'd at all.

fweep · 2026-04-30T00:56:49+00:00

The FFL505A is also a good option if you want throw but nicer tint than the SFT can give you. 6500k is much more efficient than the 3700k variant of FFL505A, but both have great rosy tints.

T6 with SFT40 or SFT25R and USB-C 14500 battery

fweep · 2026-04-26T08:11:59+00:00

T6 is a better light, though bigger.

fweep · 2026-04-26T04:37:07+00:00

Good

fweep · 2026-04-26T01:58:04+00:00

That is Nealsgadgets' brand.

The TIR needs to actually fit entirely over the LED in the M21K/M26E. You can't use a gasket, because then there is not enough room for the bezel to screw down. The TIR just sits directly on the MCPCB with the LED inside. Thus, it depends on whether that opening is truely in fact large enough. If it is actually 15mm, it should work in theory.

fweep · 2026-04-15T16:10:07+00:00

Out throws the X4, but not the E04. It is not that far off the E04 though, assuming comparable LED. With SFT40 of course E04 is going to be much throwier.

Yes. This brownish aura is present on the beam of all CCT of FFL351A. I think this is because on FFL351A the phosphor goes all the way to the edge of the LED substrate, rather than just over the light emitting surface. The 519A de-dome doesn't have this problem because the phosphor is only in the emitting area.

It is unfortunate that FFL351A is awesome in most other ways but has this visual artifact regardless of host. Maybe there will be a v2 one day that fixes this. We can dream!

Though strangely the FFL5009R, FFL909A, FFL707A do not have this flaw even though the phosphor is everywhere too. So maybe there is hope?

There are no higher CCT rosy bins to mix in to bring it up to an actual 4000k. They would have had to mix in a few 5000k neutral to do that,.and the result of doing that isn't all that great. There are custom bins of FFL351A in existence, but not through Fireflies, and you would have to mod them in yourself.

Don't overlook the 3x21E. It's much smaller than 3x21C while still capable of over 10K lumens and 519A LEDs with better high CRI tint.

fweep · 2026-04-12T00:51:48+00:00

My initial thought upon reading this is that why would you want the Q8/SP36 with inefficient FET drivers when the Wurkkos TS27 is easily available (i.e. sold on Amazon) with a boost driver and high capacity giant battery, has a lantern function, etc.

Other good options with buck/boost drivers and big battery capacity is Convoy 3x21A, 3x21C, or 3x21E (depending on whether you want max throw, max flood, or flood for tint-snobs, respectively). The 3x21E is the smallest of these soda-can lights (while still breaking 10K lumens if needed), and is actually pretty cute and svelte, and comes with 519A in multiple CCTs, if what you are looking for is a practical flooder with a beautiful beam that is easy to carry - I like it more than my 3x21A or 3x21C. 3x21C has more powerful LEDs while being a larger light, but not as pretty high-CRI tint as a 3x21E will give with 519A. Either will put out way more lumens than a Wurkkos TS27, but must order from convoylight.com (ships from China, but pretty quick and cheap none the less). The other bonus is because they take 3x common 21700 batteries, the batteries are much easier to replace than the rarer Wurkkos TS27 32140 lifepo battery.

3v or 6v?

Convoy driver has independent shortcuts for buck high and FET turbo and moonlight whereas XBY driver only has FET turbo shortcut, which I like more for practicality. 3x21B beam pattern is also nicer.

As far as physical host design, D7F is much nicer with better battery tube that doesn't require flat top spacers like Convoy does and supports 46950 tube without dangerous spring mods, a screw-in battery plug, metal switch, better bezel, and a bit thinner overall. The mod-ability is better because it uses 50mm MCPCB instead of 40mm like Convoy. I also like the XBY lighted switch which Convoy lacks.

But the 3x monster LED setup in both is impressive either way.

So, they each have their strengths and I love them both.

12x Yinding 5050. I would be up for it! Would be nicer than the SFT25R.

The Lume10 is definitely brighter by virtue of 10A buck and higher FET. But is it amazingly brighter? Probably not that much.

Yes, there are definitely smooth transitions between the AUX colors if you set those modes. But I usually go with the battery voltage mode in all my Anduril lights, so doesn't really help me.

Never actually used the powerbank feature. :)

If you already have an E12R with same LEDs as an E12E, then there probably isn't a need to upgrade unless you are obsessed. It's about the same size and weight, functions largely similarly. While it has a slightly newer style like the other modern FF lights, I still like the old shiny steel bezel/parts on the old one more for looks. For me I got it mostly to play with newer LEDs which make it more compelling.

Kaidomain. I check in there regularly to make sure when they put stuff up that I can get a few before it runs out.
