Does S21A and S21B have the same size reflectors?

I need replacement for S21B, however in the store is only for S21A

Yes, they are the same.

Oh no, I whished for 0.1%mode on T2 but also 0.2~0.5% should be fine
Simon for your others FW Drivers can you consider to put 3 more groups?
0.1% 1% 10% 45% 100%.
0.1% 1% 10% 35% 70%
1% 5% 20% 50% 100%.
It will give more flexibility based on the type of driver used and limit the maximum power for extend runtime.

Switching from 50% brightness mode to 100% brightness mode, the naked eye cannot perceive this brightness change.
So I don’t think this ratio is reasonable.
My suggestion is that the ratio of the previous mode of 100% mode should not exceed 40% at most.

Hi Simon, can you recommend which solder to use when assembling a host? What type do you use in your flashlights? Leaded or lead free?

Tin wire brand “MECHANIC”

The key is the soldering iron,
T2 solder iron , The temperature can reach 400 degrees Celsius, and use use D24 soldering iron tip

Thanks. Do you use leaded or lead free?

i use leaded.

I once asked workers to try lead-free tin wire,
Work efficiency became very low, so I gave up,

Hello Simon,

Can I ask for an option for ordering Convoy L21A with the B4-40E tint choice of XHP35 HI on the product page? (B4-40E is currently available as a separately purchased LED, but I would like to purchase L21A already assembled with B4-40E)

Also, I would like to ask that choice for the other two flashlights (M21C, M21B).

CRI90 B4-40E?
I’m not sure if it can be ordered,

Hello Simon, You had 18650 and 21700 battery from Samsung, Sony… in your store. Now you have liitokala batteries. Would you offer them again? Should I wait? What happened, when you do not offer them no more? Thank you very much.

The current prices of these batteries are ridiculously high,
If prices return to normal in the second half of the year, I will resell them,

Independently of these changes, Simon, could you introduce a single 50% mode? It would be useful for the moments when a persons needs light, but not to the max (100%). It could save some battery and produce less heat too! Thumbs Up

I think part of the problem is that a lot of people want to wring out every last lumen from an emitter that’s already nearing the top of the parabola, dumping 100% more power (and heat) into it but only getting 20% more light from it, and making maybe a 7% visual difference.

We’re back to the “numbers game” of wringing 10% more lumens by using a hideous CW emitter vs a NW or even WW emitter that just looks so much better, only now instead of quality vs quantity, it’s pushing the emitter into the diminishing-returns range of output vs input where there’s less and less to gain.

So… 50% only, for bright light that’s almost indistinguishable from 100%, but get twice the runtime? Why not just back off on what’s 100% and keep it efficient? “But ours go up to 11…”

All these mode requests – it would be so easy if Simon used open-source firmware that we could modify and reflash ourselves… These drivers are all really appealing too, if it weren’t for the proprietary firmware.

Yes, I have flashed my own firmware on old Convoy drivers, but it’s regrettably not possible on the new 12-mode ones.

I think they are, and the last time I looked up the bin Simon has listed in the description, he has the absolutely best Bin of xhp35 HI, in 4000k that is. Very nice! 4000k xhp35 is probably my favorite emitter. That or xpl-hi 4000k. Output and tint are awesome

I fairly certain they are not 90cri. I think he confirmed this once before.

according to the Cree xhp35 data sheet, the bin B4-40E is 90 CRI. that was what simon had listed in the “item description” for his xhp35 HI bare emitter in the AliX store, a month or two ago when i checked it. I cannot verify now because aliexpress isn’t opening up for me right now..

I’m not sure if it can be ordered,

I just received my package from you yesterday, containing 5 pieces of the B4-40E tint of XHP35 HI, and that phosphor exactly looks like it is 90 CRI, so I would order it in flashlights, too.

A few months before, I also ordered an L21A with the 4000K tint option offered on that product page, but when I received it, I was less than happy to notice, that it was a 70CRI 4000K XHP35 HI (I already needed the B4-40E option that time, but I did believe, that I will receive that – I should have asked exactly for B4-40E then Smile ). Now, that I can see that LED and its phosphor, the recently received LEDs’ phosphor looks like much less yellow, but rather light brown with very little orange, and that is a clear visual indication of the B4-40E being a real 90 CRI emitter.

If they are truly B4-40E bin then they are High Cri. Unless Simon was mistaken.

I just read this post, sorry JarredM.

Could you share a photo of the two? I have a K1 with 4000k xhp35, and i’m wondering which bin it is closer to, if they are that much different i can at least tell which mine is closer to.

Plus thank you for this info Adam7027, as now i know to ask Simon or at least just order bare LEDs from Simon and it them in the Convoy myself, its worth the extra cost to do it myself, if Convoy cannot do it at factory that is.

Simon,

Can you install at factory for me xhp35 HI, 4000k in the M3-C (with the xhp70 driver)? preferably the B4-40E bin?

Please let me know, i will order if so.

Simon, there are 2 good ways of charging 26800:

  • put it in a host that cones with a built-in charger
  • use a charger that has flexible wires and magnetic attachment like Folomov A1.

Yonii have the 26800 2A-rated charger, but I guess it’s not in the market at the moment. I have one, bundling with the battery (request order) when I bought my pi1man L80.

XHP35 in M21B is green compared to others (Zebra, Haikelite).

Where can I find such soldering iron?? I bought a soldering station which supposedly reaches 480C. But anytime I try to change LEDs of any light, it takes me at least 10-15min of heating and poking just to melt the solder. The host sucks up all the heat instantly. It gets really frustrating sometimes.

There’s no replacement for displacement.

Yes. I realize that 80% of my problem is really me. Something I’m doing wrong. But yes. I use flux, always cleaning the tip to remove old solder and oxidation.

I prefer the first one,
I don’t want the buyer to spend more on the charger,
