If I want to turn on moonlight from off state with click-hold then the timing needs to be perfect. If its too short I get the memorized brightness level, if its too long the light starts ramping up. Most often I end up with too short press because of this “fake” moonlight on button down press (press the button, see the moonlight, think “on nice, that’s what I wanted”, release the button too soon, BOOM!!! get 1000 lumens of memorized brightness).

Change the timeout values to something that works for you, recompile, then flash.

I have that particular delay set to 28 ticks IIRC and its about perfect for moon timing. The only problematic thing ive come across with Anduril is that sometimes if I turn on using moon shortcut, leave it on a few secs, then shut off. It wont memorize moon for some reason.

Is the XP-L HI worth the extra vs SST20?

It doesn’t memorize the floor, ceiling, or turbo levels when they’re reached by a shortcut. This is on purpose, because people didn’t like losing their memorized level after using moon or turbo. To make it remember moon, the user must ramp to it… typically, by ramping up a little then back down.

Basically, it behaves that way because that’s what people asked for.

a 5000k xpl is a little to yellow for me but 6500k xpl to white. How does 6500k sst20 look?

Where do you see that the 5000k is yellow? It’s not.

I’m not bothered by the delayed turn off because it is only a fraction of a second. However, trying to get it to start in moonlight mode but end up with full blast in the middle of the night with the wife asleep is very annoying. I wish that can be fixed.

Lol

I’m also replacing our bedroom fan lights with Alexa enabled LEDs so we can use reds to preserve night vision and not bother each other when our schedules conflict with sleep habits. Soon there may be no need at all lol

Well, knowing its behaving as designed is a consolation and after further thought, it actually makes sense.

I’m thinking o f getting a D4s ,I like the XPLHI 6500k version of my D4 & I’m thinking of getting that in the D4s but what’s the difference between it & th SST-20 6500k version ,I know it has more throw ,do you sacrifice flood? Is the tint the same? Is it more power hungry?

It would be nice if we got a side by side pic of the tints and beam shape for each of the different emitters. I’d bet it would help people get off the fence and order.

But hiding flashlight in your mouth before diving into muffin is very rewarding.

It’d be really nice if it was standard for flashlight companies to include a “cd/lm” metric for every model and every emitter type. This goes a long way toward giving people a good idea what the beam is like. For example, is it a 2 cd/lm flooder, a 8 cd/lm EDC light, a 35 cd/lm compact thrower, or a 200 cd/lm dedicated thrower?

In order to pick the right firmware for YOU, maybe there should be a survey.

“When I press the button, I want the flashlight to respond immediately: (please circle one)
(AGREE STRONGLY) (AGREE SOMEWHAT) (NEUTRAL) (DISAGREE SOMEWHAT) (DISAGREE STRONGLY)

When I adjust levels, the light should not flash or flicker:
(AGREE STRONGLY) (AGREE SOMEWHAT) (NEUTRAL) (DISAGREE SOMEWHAT) (DISAGREE STRONGLY)

The light should remember my last-set ramp level, even if I have used a shortcut to moonlight or turbo:
(AGREE STRONGLY) (AGREE SOMEWHAT) (NEUTRAL) (DISAGREE SOMEWHAT) (DISAGREE STRONGLY)”

and then the script compiles it! Smile

That’s more or less what the “USE_*” flags already do. It would only need a script to set or unset those. There are lots of other software projects which work this way, and even an entire OS based on the concept. Gentoo makes heavy use of “use” flags, both on a per-package basis and system-wide, to let people customize things exactly how they want… but OTOH, it also takes a great deal of time and electricity to compile everything from scratch all the time.

Anyway, use the USE_ flags. Smile

This is the D4S thread, so it may be disrespectful to post beams from another flashlight (in this case, it is the PL47)

Nichia 219B vs SST20-4000K vs XPL-Hi-“neutral-white” LEDs on a PL47:

The SST20-4000K is a bit more throwy and also a bit brighter than the Nichia 219B, when using similar battery at fully charged levels..

Thanks for the beam shots. I’m not familiar with the PL47 but is this indicative of how they would look and perform in the D4S? I’m surprised the SST-20 isn’t closer to the XPL-HI in terms of output and beam profile.

This D4S is marvelous! i have read the 52 pages of this post and now i want one with the SST-20 5000k! tongue-out

I'll think i just wait a little bit for some beam shot of the SST-20 5000k emitters added recently.

 

Ty for the nice review Toykeeper, and too Hank as well for this nice flashlight.

 

Now i just need to be strong and patient. laughing

Ordered a D4S with sst20 3000k. Already have one with sst20 4000k which i like.
But i thought i might like 3000k. I Was about to order the M43 with 3000k, but not sure i Will like it. So i ordered D4S instead to try it out, because D4S is cheaper. Big Smile
I also ordered the Another M43 in sst20 4000k. Cash

Anyone has the 3000k yet?

Hi,
Quite a lot of reading Wink But, which led should I use in terms of brightness up to 5000k? SST or?

Brightness is the highest with the XP-L HD.

However, for best usability in all conditions, the SST-20 5000k would be your best choice.

Is it noticable difference? How many lumens? I guess SST is more focused, giving this light a little more throw?
