In terms of max lumens on XP-sized emitters, the scale is generally (from most to least):
  • XP-L2 HD
  • LH351D
  • XP-L HD
  • XP-L HI
  • XP-G3
  • 219c
  • XP-G2
  • 219b
  • XP-E2

If I recall correctly, at least. Assuming other things are equal, like color temperature and CRI. Warmer tints and lower CRI generally produce fewer lumens per watt.

So it’s not at all surprising that a LH351D would beat XP-G2 on lumens. It’s enough steps above that it can still put out more light even with somewhat higher CRI.

Thanks for that information. I wonder where would the XM-L2 (or XM-L) fit in terms of lumens/power (though they’re not XP-sized..)?

I’m also very impressed with how nice the auxiliary lights look. Just an idea, would it be possible to make the auxiliary leds glimmer individually by a future driver update? If that’s too hard, maybe having the LEDs “breathe” simultaneously.

Not really. The breathing effect costs a lot of power. Instead of just powering the LEDs (0.03 to 0.90 mA), it requires keeping the MCU awake to pulse the emitters on and off fast enough that it looks like it’s dimming. The MCU by itself requires several times as much power as the LEDs (2 to 6 mA). So “breathing” mode would be less bright and have only a fraction as much runtime.

You could make it “breathe” by changing the firmware, but I don’t think it would be worthwhile.

The side indicator LED of the BLF Q8, when installed with Anduril, can be configured to have breathing effect (On-Off-On-Off) = is that also costly in terms of power consumption?

XM-L2 would be a little lower than the XP-L HD. Same/similar forward voltage, and therefore same current, but the XPL HD is, I believe, available in high flux bins than the XM-L2

The breathing effect is costly in terms of power regardless of whether it’s on a button or front-facing LEDs. However, Anduril does not have a breathing mode. The closest it has is a blinking mode, and that doesn’t really cost any extra power.

The breathing effect…


What is the breathing effect?

As I said above, I’m new to programming flashlights.
While I’m waiting for the hardware, I would like to clarify something.
This command:
avrdude.exe -p attiny85 -c usbasp -Uflash:w:anduril.YYYY-MM-DD.EMISAR_D4S.hex:a
in command line in the Windows (10×64 LTSB) is enough for purpose of reflashing firmware or I must first delete old firmware from MCU with any additional commands?

Could you give me ONE command for successful flashing Anduril.

Thank you!

Not toykeeper, but this command is enough to flash the D4S. You still need to have avrdude installed

Exactly. That is the breathing effect.

In terms of implementation, it is done by enabling PWM on the indicator LED pin, and then cycling a slow triangle wave (linear zig-zag) on the PWM level. It’s really easy to do, but it requires keeping the MCU awake in order to generate a PWM signal. So in that mode, about 95% to 99% of the total power goes toward running the MCU, and only 1% to 5% for powering the LED. It’s very inefficient.

In contrast, simply turning the LED on and then putting the MCU to sleep makes the button brighter while also greatly reducing the amount of power used.

On the light I measured, breathing mode used about 4 mA on average. Meanwhile, I’ve got moon mode running at about 1.7 mA in Anduril. And the BLF Q8’s button LED uses about 0.1 mA at full brightness. Or running the Q8 button LED in blinking mode, it’s about 0.1 mA while on and 0.01 mA while off, with a ratio of 1 to 8. So overall it’s about 0.03 mA average while blinking.

So on a 3000 mAh cell, I get roughly the following runtimes:

  • Breathing mode (Astrolux et al): 1 month
  • Moon mode (Anduril): 2.5 months
  • Button LED (Q8, high): 3.4 years
  • Button LED (Q8, low or blinking): 11 years

This huge difference in runtime is why I haven’t added breathing mode.

I wondered why my MF01/02 went flat so quick!

I’m gonna sell.

The lack of Instant Turbo is making the D4S a bugger to review, I’ve had to re-shoot several times noticing the beamshots aren’t bright enough. I’m too used to my many D4’s.

If you want instant turbo from off, all you have to do is set the ceiling level to 150 (1 click during the ceiling config).

The one I ordered from Hank came today….my back up D4S lasted about 2 minutes…….

Now it’s my wife’s D4S….. Flat Stare

My green one from MTN Electronics got here Saturday and has the programming via’s like the green one shown above right. Richard was positive that the optics are glued to the MCPCB but mine wasn’t, so there seems to be a couple of variables in these, maybe some first runs got through done one way before they figured out a better way?

I picked up a couple of flat top batteries for the D4S (it’s finally at Canada customs! Hooray!) and was wondering of one would be significantly better/worse? My TA lumen tube is stuck in customs (9 days now) so I thought I’d ask the collective wisdom here instead of just guessing.

I’m hoping this hasn’t come up already and I missed it. Apologies if it has.

Well that makes things interesting. It’s both easier and harder to connect to the line of flat pads — easier because I assume it fits a standardized set of jumper pins or something, harder because it has no holes so one cannot just shove wires through it.

I hope Lexel’s connector becomes widely-used soon, and I hope we can get someone to make and sell the keys or flashing kits fairly cheap.

Cheers! For some reason I thought that just applied to the stepped mode, aaarggh!

Looking at HKJ’s tests, the Liitokala has more capacity, but the IJOY has less voltage sag at high current (15-30A).

Yep, they are a really good performing cell….IR on my Sky RC charger puts them at 16.

Had to check my D4S with only the driver spring removed and a brass contact added as the only mod to an otherwise stock light. 5,650lm on the other IJOY @ 4,21v.

Also checked the wife’s Stock D4S I got today from Hank using the IJOY 26650 4.21v off the Sky RC charger 5,050lm @ Turn on.

The IJOY’s are pretty freak’in good!

I got the light the other day, with the V3 Hi’s. Throws further than expected and with a better beam profile than expected. The UI is great. The aux LEDs are pretty. Very nicely done. This light is a big deal.

It doesn’t come up often, but this wasn’t the first time someone asked about that particular detail.

Yep! Set up exactly as T/A’s instructions for the diffuser’s, I check calibration before each use… And I keep it covered with the BLF GT Hoodie.

It’s helped me find the weakness in a few of my mods, that I have gone back thru them and made them a bit better. Thumbs Up

So here is the comment made by skylumen ( pro modder ). He doesn’t go to blf. Here is what he wrote, “ D4S just came in. WOW, this is the best Emisar.”

Thanks TK, Hank, and everyone who succeeded this project.

Did my first UI flash! Woot!

Received a bunch of errors…hex file was in wrong location…(noob)

A little tricky, but had great instructions and am fairly computer savvy…was able to power through it…

Put in correct location…Anduril flashed!

Thanks for help Fate0n3 and ToyKeeper!!

When I'm spending on¥ foolishly, I like to do it i$el¥...

I have all the flashlights I need, but not as many as I want...

Kawi, that is freaking incredible that you got 5000+ lumens. Which emitter did you get? I only got 3,800 lumens with my D4s XP-L HI 5D using my TA tube calibrated with Maukka lights. I’m kind of disappointed. I was expecting 4.5k lumens

Hey skv, I told you. I got 5000 lumen @ turn on for my xpl 5000k.. Kwai tube has been calibrated with maukka lights.

ZozzV6 - Those are the same four lights in the same color combination as I have. The only difference is I usually have the short tube on the D1 to make it more pocket-friendly.
