【convoy】H4 and B35AM options are updated

Hopefully they offer some better tints and lower CCTs. The SST40 has fantastic efficiency and performance but terrible tints.

SFT40? Without (preferably ultra) high colour rendering, another one I'll for sure pass on. O:)

Would it be possible to get the SFT-40 and SFT-70 datasheet?
Because I found the Design Guidelines for SFT Chipsets Assembly (SFT-10, SFT-16 and SFT-20).
In it, it says that the thermal pad is electrically active, it is common with the cathode.

Just seeing that sbt90.2 on 20mm mcpcb drop in the AX store, Simon you are the King of flashlight modification supplies and straightforward , elegant flashlight design. This is exciting, I have been recently researching what to do for an mcpcb for a sbt90.2, and now I can just order one from you. Amazing. Thank you!

Simon, would be nice Quad S21A/B style side switch
with variable tint and Nichia (E21A?) Leds.
An alternative to IF25 with smaller head size

I have a question- I have the yootoo (amutorch) sd3 small 21700 thrower and I’ve done a couple led swaps and now it’s just not working. I think the driver is shot. I pulled out the driver and now I need to replace it. I want to run either an xhp50.2 (3v) in this or perhaps even a sbt90 later at some point (just for fun). So I am thinking I should get a FET or direct drive driver. It is a mechanical tail switch (not sure if it’s forward or reverse). What would be a driver on simons store that would fit this application? As much as a 6amp or 8amp driver is probably better, I want to be able to have open access to turbo in the even I do put that sbt90 in it some day.

I didn’t measure the diameter but it’s 22mm I think. The mcpcb is 20mm.

Thanks in advance.

8A driver

Here's a fragment of a PM I had with another forum member. Here it is in case someone else can benefit from it:

P.S.: the thermal management stuff also involves most of the newer Convoy drivers, it is linked to the newer 10-pin MCU. If I recall correctly, the negative thermal coefficient (NTC) resistor is connected to pin 8 in the MCU.

The CULPM1 in Convoy store is 8RF, the 5th bin of 7, 1690 lm - 1900 lm in the range 1320 lm - 2120 lm at 6A.
The CSLPM1 is 5P, the 2nd bin of 4, 450 lm - 500 lm in the range 400 lm - 630 lm at 1.4A.

The bins are not directly comparable, but the CULMP1 bin apparently is better than average while the CSLPM1 is just average.

Just added a LH351D in 2700k and 5700k to my collection. (Note: the LH351D were on 10, XM-L2 8x7135 on 35, and 219C/SST-20 4x7135 on 100%)
Left to Right - Cree XM-L2 6500k, Cree XM-L2 4500k, Cree XM-L2 3000k, Samsung LH351D 5700k, Samsung LH351D 2700k, Nichia 219C 5700k, Luminus SST-20 2700k.

Simon just added 8*7135 12-groups driver with temperature control and 20mm XHP50.2 3A driver to the store.

It’d be better if it was a 3A version of the 5A 12 group driver. Constant current, and single sided.

This one looks like a slight modification to the old 7135 driver. Same doubled sided issues with the S2+.

Does anyone else hate soldering drivers to pills? It’s a mess and it’s hard to reverse later for swapping parts around.

This is a big step. Kudos for Simon for implementing it. With the 10 times tap I keep entering the config mode unintentionally which is very frustrating. With this driver that won’t happen anymore.

@Simon, when will the 5A 12 group driver receive this update?

It’s already here. 17mm, 20mm, 22mm, boost 20mm, boost 22mm and 8A already have 20 clicks. I just don’t know if the boost for xhp70 is with the new soft.

I trimmed retaining rings to fit. This is also tedious, but I didn’t even want to go down the road of heat up the entire pill.

I thought I only had to do this because I used QLite drivers. Does the Convoy 8 x 7135 driver interfere with the retaining ring, too?

Is there any way to disable mode memory on T2 (latest version)?

The convoy 7135x8 is pretty much the exact same driver with different software and it’s red instead of green.

Probably not. I wish it had a programmable driver. At least memory on/off.

It’s possible. Reylight has a AA/14500 driver with programmable modes and memory on/off.

The 5A 12 group driver has been updated several months ago.
