【convoy】H4 and B35AM options are updated

You can get the M21A host, the 20mm 6v driver and a XHP70.2 and do it yourself but the better driver for the 70 is the 22mm 6v driver. The lower amperage of the 20mm driver doesnt really take full advantage of the 70.

Here’s my awesome comparison of the L21B / C8+ PM1 vs SFT40

Hello Simon,

Can we have group with: 1% - 3% - 10% - 35% - 100? I feel like sometimes 1 is not enough and 10% is too much. 3% mode in between would be perfect.
Maybe 1% as moonlight/firefly mode and 3–10–35–100 as low/medium1/medium2/high?

Also, would it be very difficult and/or expensive to create driver where users can program their own groups? For example bluetooth connectivity and smartphone app or usb cable and PC/web app? I’m curious.

Cheers
Thomas

Doubt anyone has implemented firmware for that, not even Toy Keeper who wrote Anduril.

I guess he could do something using the existing ramping driver firmware that allows the user to set the brightness for levels 1 & 2

lucidrv2 firmware on H17fx driver allows you to program any mode order and number you want. It’s all done on the light though, not via Bluetooth or anything. Bluetooth in a flashlight just seems excessive to me. But, having flashing pads for custom firmwares on Simon’s lights would be a welcome change.

great video! what 8a driver are you using in the c8+? I thought the convoy ramping driver maxed out at 6a.

Perhaps completely irrelevant to this forum and this thread, but LUX-RC created a programmable driver using a very clever optical system with a light sensor on the driver, one would configure the modes and other settings on their website which then will generate a series of strobes and you would place the flashlight against your monitor receiving the flash signals, similar to how IR remotes works. To me this is much more robust than bluetooth and truly universally compatible, no need to write a separate app for it and hoping for device compatibility.

A true masterpiece of the flashlight hobby at a ridiculous price range that is inaccessible for most.

For a decade I hoped to finally be able to justify paying and waiting for one of their lights but now I have just given up. It’s simply out of my reach.

Uhh, yeah, we know about the LUX-RC tech. A LED is a diode and it can "read" light as well as output it. Some ATTiny85 drivers even wired in the input on pin #7 but never ended up using it. A design EE I worked with suggested it and I told TK and she dabbled with it for a while, but not sure how much success, but then at the time, there wasn't much code space available in the 85 MCU. Pretty cool because no additional sensors are needed.

I just gonna leave this here…



I made comparison between T2 and T3. Different drivers, different leds, but it was fun :slight_smile:

Appears T3 driver pulls alot of current, with AA battery! I like it

And the highest mode is sustained for 9 minutes :slight_smile:

If your measurements are correct, the T3’s new driver has a very poor efficiency :open_mouth:
T3 100Lm / 2,1A
T2 115Lm / 1A
Is it possible that you accidentally swapped the 14500 / AA measurements?

I wanted to buy from the new driver so far, but this is disappointing. I also don’t like the fact that the output is as poor with 14500 as with AA.

Hello forum,anyone have experience with SFT70?,i’ve seen video of SST70,but none of the domeless version. I have one on the way,along with convoy xhp70 4,8a6v boost driver. Planning to set the led in my M21d. Any insight would be very helpful
Cheers

Sorry for the confusion. I don’t have reliable way to measure lumens, those are just number relative to each other.

It should be interpreted this way:

  • T2 LH351D 14500 has 189% of T3 219B 14500 brightness.
  • T2 LH351D AA has 115% of T3 219B AA brightness.

They aren’t comparable in any different way:

  • They doesn’t mean that output on different battery type is equal.
  • They doesn’t mean that output on 14500 is brighter by 74%.

But how can the T2 AA be brighter on less than 1/2 the amps of the T3 AA? 1 amp vs. 2.1 amps? Think this is what we are confused about.

Affected by the accuracy of the chip and the sensitivity of the human eye to the difference in brightness. I estimate that many people do not feel the brightness change between 1% and 3%.

i will have sw519a and BM35AM available after one or two months,
I got some samples.

Great to hear, what CCTs are you planning to offer ?
All 9080 color rendition ?

The 219b is that inefficient compared to the lh351d.
