FW3A, a TLF/BLF EDC flashlight - SST-20 available, coupon codes public

C and D would be the most practical imo.

I’m using the latest Anduril on my 11,000 + lumen Q8 and I LOVE it!

Blinks at the default positions works well for me, the 4 SST40’s can go VERY low on the ramp floor (too low!) and the candle light fix is superb! I find the lowest setting on candle to be the most realistic with my diffuser in place (and some tint correction via Lee filter to bring the SST40’s in line)

Ramping is ultra smooth and quick enough to not be a drag, still easy enough to select a desired level of output.

If one has memory issue to the point of not being able to use firmware like this, I’d venture to say use of Li-ion cell powered lights should be discontinued… my memory is as fallible as most anyone’s and even I can set this up and use it without much trouble. (some of the lesser used features give me problems at times, but of course that’s what the UI diagram is for)

Love it TK, thank you SO much! :heart_eyes:

That table! Wow! Afraid my lights might exceed the maximum current draws by a wee bit…
:blush:

Thanks for compiling the table, ToyKeeper! :+1:

WOW indeed, power but also dirty amounts of runtime for example as a nightlight :+1:

1 for me, thanks.

This little light should be really handy for general EDC use, but with the benefit of some power up top when needed. Of course, it won’t run long at Turbo levels in a light this small as heat will become a paramount issue, but it’s really nice to have it there when you need it and TK gives us the ability to set a ramp ceiling at a nice usable level with a quick double click going to Turbo for that on-occasion need of a blast of light. That really makes it a great application in my opinion, I use the ramp ceiling at around 60-75% such that a double click really steps it up, this lets me easily control power drain for the best EDC capability to date. :wink:

I didn’t have the graph earlier, but here’s how the latest thermal test looked.

This started adjusting from the highest current-regulated level, which measured about 1100 lumens or close to 3 Amps. Output stabilized at about 7 minutes. I haven’t tested it on full FET yet, but I suspect it will probably need some changes in the response curves to make it react faster.

Wow TK,the UI looks amazing. Thanks for the table and graph. Great work. Looking forward to playing with the light and using it as my EDC.

Pepinfaxera, can you put me down for a second light please.
Thank you

Do you know at what temp about it stabilized at?

For testing purposes, I set the limit intentionally pretty low. I was aiming for a stable level of about 200-400 lumens, and … that’s what I got. I think I told it that the ambient temperature was 20 C, and set the limit to 43 C, but I don’t remember exactly.

I wanted it to exceed the limit pretty easily and then step down somewhere slightly above the 1x7135 level. I could have set the limit much higher, but that makes the regulation problem easier to solve… and I wanted to see how it behaved on a harder setting.

Next I need to do full FET testing, since it’s the next step up in difficulty.

Looks like it worked as intended. Be interesting to see what it would do around 55c limit. What can the components tolerate? Typically up around 100c right?

I expect that turbo will overshoot the temperature limit before the light can settle to a stable level, so I wouldn’t put the limit too close to the hardware’s maximum tolerance.

The thermal sensor is inside the tiny85, which doesn’t have a great thermal path to the emitters. The measurements lag behind by quite a bit, so the response is lagged too. It tries to compensate for this by guessing where the temperature will be in the future, but that doesn’t entirely eliminate the problem. So the actual temperature goes higher than the limit at first, if the power is turned up high enough.

The firmware won’t allow a limit higher than 70 C… but it lets the user calibrate the sensor, so it’s not very hard to bypass that limit.

On a related note, that could potentially save a bunch of button presses while configuring things. If you tell it room temperature is 1 click (1 C), and then set the limit to only 1 click (30 C + 1), it’ll effectively have the same results as if you set room temperature to 20 C and the limit to 50 C. But the tempcheck mode will display numbers about 20 C too low.

I do not see him registered
