Looks like the Convoy BLF discount is no longer valid due to changes in the aliexpress website. The old method to apply it no longer works, and even after communication with Simon, it did not get applied before shipping.

It seems like bypassing AliExpress for custom orders is now the way to go… either there’s no way to defer payment and send a message, or it’s been made intentionally hard to find.

Aliexpress used to have an intermediate status between submitting an order and processing payment. This has been removed recently so the previous discount method no longer works. It’s not a big deal — I’m not going to waste everyone’s time over $2, I had just hoped to recoup the Aliexpress tax.

I think it is still there but hidden. I used it about month ago and had serious troubles finding it. I may have used a failed payment to get an unpaid order.
I’ll try to find the way on my next buy (Friday).

this is necessary when your hands are busy and you need to inspect the territory. Let’s say you have a machine gun in your hands and your hands are not free .. In my case, there is one lamp on the handlebars of a bicycle, and when riding you need to inspect the territory at night ..

It’s true you need throw whenever you are going fast. I usually am wearing a helmet when biking so a traditional headlamp would not work well. I use a convoy s2+ with XPL HI and smooth reflector that’s strapped to the top of my helmet.

I can't see the problem. You should click pay, then when transferring to your bank page to log in, just close the whole tab, then open new Aliexpress page and you'll see your order is "awaiting payment". It works for me, at least...

But I'm usually not camping with a machine gun... :roll:

 

But I get it. Wink I use headlamp only when walking. In forest I have a floody TIR headlamp and a small thrower. But if I got in the mountains, I'll get only headlamp to save weight. In this case it would be e.g Xtar H3 - so OP reflector and not throwy led. I think bigger led (like XHP70) + OP reflector would be perfect for me for everything. But I don't like combinations like XP-L HI and a SMO reflector. Too throwy.

So Simon, please make us a bit throwy headlamp with sliding diffusor  Innocent

I am perfectly aware. I contacted customer support and was told to use the Android application, you will be given the Other Payment Methods option (but add to the cart first, or else it won't work). However, this is only a workaround, so make yourselves heard:

I didn’t know that there is a BLF discount code for Convoy and I buy quite a few

Hi Simon.
Will a flat-top battery adapter be available for separate sale?

Do you have plans to create a flashlight with 3*XHP50.2 or 4*XHP50.2? May be 3*XHP70.2 or 4*XHP70.2?

Sorry for my poor english.

My bike ride is not very extreme, so I ride without a helmet, but now, as you said, the distant rays of standard headlights are not enough. I would be very pleased with the Convoy S2 + lamp with the SST40, it glows well at a distance, but they do not have an L-shaped model. In the case design, difficulties may arise due to the case design so that it does not overheat, I don’t know .. – I’m talking about Convoy s2 + headlights on the SSt40 .. For now, there is a Nitecore Model HC33 (CREE XHP35 HD), but Convoy can also do something like that ..

4*18650 battery pipes from different manufacturers are about the same size. Perhaps the buyer will need to grind in place. The idea of such an adapter is beautiful in itself, you definitely have the talent of an engineer.

But i’m not sure whether you can use it on other lights, the springs might be too short.

I don’t think I will sell it separately, but if you need, I can send one to you for free.

If you think that memory-modes in your drivers is necessary, then let it be, but =======>>>>>>>>>>>>>>

Please give us a choice!

All I need is S21A without ANY memory-mode. I want to start with LOW-mode. Always.

Next mode memory? Wouldn't a current/last used mode memory be muuuuuch more preferable? As far as I understand, that is.

The diagram is wrong, it’s off-time memory.

As far as I now and/or think, off-time memory means whatever mode is memorized once the flashlight has been off for a given amount of time, maybe 2 - 3 seconds. But what whatever mode? I think you're trying to tell it's the last used mode, isn't it?

When the next mode is the one memorized we just call it next mode memory.

Pseudocode:

  • Next mode memory:
    On start
    current_mode = stored_mode
    stored_mode = current_mode + 1
  • On time memory:
    On start
    current_mode = stored_mode
    stored_mode = current_mode + 1
    After x seconds:
    stored_mode = current_mode
  • Off time memory:
    On start
    if too_much_time_elapsed
    current_mode = stored_mode
    else
    current_mode = stored_mode + 1
    stored_mode = current_mode
  • No memory:
    On start
    if too_much_time_elapsed
    current_mode = first_mode
    else
    current_mode = stored_mode + 1
    stored_mode = current_mode

too_much_time_elapsed is when enough time had elapsed to discharge a capacitor or erase/corrupt a known pattern in unpowered ram, depending on the driver having a capacitor or not.

Cheap flashlights have next mode memory because they don’t want to spend a few extra cents in a capacitor+resistor and the memory trick is unknown to them or the time is too short (i.e. unlike the attiny13 they only have DRAM, not SRAM) in their drivers to be useful.

Very nice. I would have been happy if the current 6A SST-40 driver was simply made without memory (I have never understood memory, mode memory makes a flashlight unreliable Flat Stare ) but a biscotti interface is a nice extra Smile
