The D80 driver was designed by Lexel. Maybe ask Lexel

If it was off, there’s something wrong with the switch. That should physically break the current path, regardless of what the driver’s doing.

Very weird stuff, it has a mechanical switch, the circuit is completely broken when switched off. It uses a common switch (I believe an Omten) used in many other lights. As far as I’m aware the BLF D80 is one of the best designed lights out there, mechanically everything is simple and well-proven. Only the user interface (modified biscotti by flintrock) was a gamble but appears to work very well.

My two D80V2 do not drain cells fwiw.

Could be a soldering defect (slight solder bridge) at the tail spring causing a tiny trickle current bypassing the switch, not enough to start up the MCU and cause a faint moonlight, but enough to drain cells?

i thought originally the first cell was just defective and went dead, so i tried a second, ( and third) and killed them too the same, drained the voltage to near zero.

Wow, that's terrible, DBSAR!

(I hope your experience is an isolated incident.)

Lux-Perpetua · 2020-08-24T05:02:23.000Z

Den, if you want I can inform Jacky (WildTrail/LuckySun) about this incident to see what he can do about it. Unfortunately, Sven („TheOnlyDocc“) has never shown up again since 09/2019 and all communication attempts to reach him were unsuccessful. So, I would try to help you in his stead.

Cheers,

Thomas

Does the BLF-D80v2 have a forward or reverse switch?
How does its throw compare to a good C8 with SST40 5000k?

Reverse.

If by good C8 you mean a direct drive one like this light is then the C8 will have longer throw.

Thanks

Reverse.

But this one is more compact and feels better. And this driver plus firmware is superb.

Seems like a good choice of emitter too. Fantastic light, I need a forward clicky though with momentarily half press to last used ramp.

Would be great if these lights could be offered with a forward clicky option for people who need a tactical style light.

contactcr · 2020-10-27T13:30:32.000Z

Forward clicky makes it a few mm longer and IMO makes a lot of the modes more difficult to transition between. I don’t mind them on some lights though.

I see you said “ramp”, none of the lights with only one mechanical switch will “ramp”. However, there are dual switch lights that can work like you describe (Sofirn C8F). A bit bigger light though.

Depends. If a driver uses a attiny 13 and up MCU (best with attiny25 or higher) it could be flashed with Toykeepers Crescendo, which ramps. Reverse clicky mechanical switch is easiet to use.

I should have known a senior member would mention this, lol. That is hardly a solution for 2 month member with forward switch request. BUT, yes technically correct.

Sw1f7 · 2020-10-27T14:01:03.000Z

Thanks for all the advice

This is probably getting way off topic but…

Here is a link to a Convoy C8+ with ramping
Convoy C8 with ramping driver

Will this work with a forward switch?

I have a C8G and it works great (I realise that it has two switches as mentioned, just saying). Set the ramp and then just use the half press to access it. Fantastic for night patrols. Only gripe is the CW tint else it would have been perfect for me. Hence me looking at the BLF-D80v2 which seems like a awesome light. Another user suggested that I could swap the emitter of the C8G but I’ll rather look for a stock light that meets my needs before resorting to modding.

Sofirn SP35/IF25 clip fits very well

This is an old message, but I just saw the question now. Will share my experience with regards to Convoy ‘ramping driver’ and a forward switch.

When the Convoy M21A was first released, it only had SST40 LED option, and uses a forward-clicky tailswitch.

I’ve tried the Convoy C8+ with SST40 LED and the Convoy ‘ramping’ driver (which uses a reverse-clicky tailswitch).

I wanted to try the same on the M21A (the M21A is basically a C8, but uses a 21700 battery instead of 18650 battery), so I asked Simon of Convoy to install an M21A for me, but uses the “ramping driver” instead of the default “4-mode driver” (back then, the “new 12-mode driver Biscotti clone driver” had not yet been developed, so there’s only the 4-mode driver and the “ramping” driver available for the SST40 LED with Convoy’s offering.

What I had not expected was that Convoy M21A used a forward-clicky tailswitch for the M21A flashlight.
And thus, the “ramping driver” does not work as expected — as it requires a “half-press” and “several half-presses” to get to the configuration settings.
With the forward-clicky tailswitch, “ramping” function won’t activate for the M21A.

I had asked Simon if there is a reverse-clicky tailswitch available for the M21A, but he said that only forward-clicky tailswitch is available for the M21A model (I think that was in the earlier stages of production).

Since I preferred reverse-clicky tailswitch, I stayed away from the M21A model, but a longer time later, I decided to order the M21A again when it was introduced with different LED variants.

When I received the M21A, I notice it was now using a reverse-clicky tailswitch now. So I swapped this reverse-clicky tailswitch on the M21A with “ramping driver” and it works now. The earlier forward-clicky tailswitch then went to the new M21A I got that uses the 4-mode driver (which works OK enough with forward-clicky tailswitch).
