Emisar D4S review

Nope, no nice nifty little orange LED - good job. I didn't look close enough and just thought it was a reflection. When looking at the LEDs I was wondering if mine were orientated the same compared to the switch and yes they are.

It shouldn’t make any audible noise during use. If it does, there might be a loose connection or it could have possibly been flashed with the wrong fuse values. The latter is easy to test though. Go into beacon mode and measure the amount of time between flashes. If it is close to 2 seconds (with default settings), the processor is running at the correct speed. But if it’s a lot longer than 2 seconds, the processor is underclocked (which would make PWM audible).

Does anyone know how to adjust secondary LED brightness in Anduril?

Lockout the light with four clicks. In lockout triple click to change secondary led mode for lockout. Or click-click-hold to change for unlocked OFF state. Thet will cycle through the options.

I have the D4S 3A too, on my Integrating-box I got 4650 with a 5200mah AWT 26650 and 4400 with 2 x Shockli 5500mah 26650 though both the Shockli cells gave me 4600 after the voltage dropped to around 4.17v for some reason.

All my D4 XP-L measure 4000-4300 depending on tint/optic. All my Emisars measured around 1000 lumens lower on my TA tube.

Thank you toykeeper. So this only sets the secondary led brightness level for lockout mode? I notice once I take the light out of lockout mode the secondary leds go back to lowest setting.

Ok. Great number. Thanks for the input…

Youre welcome but I’m not Toykeeper :smiley:
I told both lockout and unlocked setting method.
Set for lockout: triple click
set for unlocked: click-click-hold

Ha ha ha thank you Zozz! I apologize. I am using my phone and the screen is small!

Today I removed the brass driver contact, and made a thinner and larger diameter copper contact out of some copper rod I had laying around from a past project and drove it down to the pcb during the melt. Bypassed the rear spring with pure copper braid, soldered directly to the spring and board in a crossed overlapped fashion, it looks like Crap, I kept fighting that damn strong ass Magnet, kept attaching itself to my Iron!

A 30T @ 4.21v off the charger, I got 6,230lm at turn on….and the head is still stock XP-L HI V3 1A. I’ll run it for a few days… see if it lasts…. I have a third D4$ coming that I’m keeping stock… :wink: I mean it!

OH I SLIGHTLY Dented my 30T in the process, :person_facepalming: forgot to put the copper tail cap spacer in :rage:

Damn, you guys want overkill.

6000 lumens at turn on… that is BLF Q8 levels of brightness.

I do wonder if it is possible to reach 7000 lumens, although that would be at the absolute max of these emitters and would probably the highest flux density light in the world.

Congratulations! You’re having fun now!!
I too forgot to CD before flashing.

replace leds with XP-L2 and there you go 7-8000 lumens

Working on 7000+ Blue, should be there sometime Friday… :wink:

Haven’t even bypassed springs yet… lol

Edit: Up to 6503.25 lumens at start now. :smiley:

Same 80 CRI 5000K Samsung LH351D’s, I pulled the driver spring and make a shallow solder blob on the driver and then put one of my large Blue springs in the tail cap with a 20ga bypass. This is with the LG HG6 20650 cell, rested and partially used. :wink:

I have 25 of the LH351D coming Friday in a W power bin, 2 bins up from what I have in it now. :wink:

What is the part number and parameters of that LH351D? CRI, color temp ? I haven’t tried Samsung leds yet.

I have 80 CRI 5000K Samsungs in my D4S at the moment. The new ones coming in, the W bin, those are 70 CRI 5700K. I think they’ve been testing up around 2000 lumens or more, similar to the XP-L2, but with a better beam profile.

Look for em at DigiKey, they have had a good selection here… you just might get lucky. :slight_smile: (They’re only a couple bucks each, so the price is right as well)

Edit: There are 90 CRI offerings too, albeit at a lower power bin.

Where do you buy them? Do you see any green tint?

If you dont like a 6500 lumen, i will buy it. Lol

It’s not so much a matter of like or not like, it’s a matter of I mod to see what can be achieved, where can this one go, ya know? After this one, it’ll be another one. And so it goes… which is why I have over 200 lights.

I’ve wondered before if it would be feasible to put a sense resistor between the FET and the emitter lead, to tone one down to reasonable after finding out how much of a monster it can be. Sometimes I just like a light, but full monster can be too much so it can be necessary to back em off. Anduril helps there as the ceiling can be set to a reasonable level and the double click reserved for Monster duty. :wink:
