Hi guys,
Looking at getting these 26650’s for this light, but I’m slightly concerned about the dimensions:
Dimensions: 26.65 x 66.55 mm
They seem awfully fat.
The other listed 26650’s is what I’d prefer but can’t find anyone that’ll ship to Australia.
Edit: any Aussies got the Shockli 5500mAh into Aus?
Not Shockli. I’ve got these on the way. Is it worth a dedicated “Batteries shipping to Australia” thread? Maybe someone can run a GB and get a batch of decent sells in via FedEx/DHL and distribute via AusPost? Maybe ask supersports600 if he can get a batch in?
My battery tube I.D. measures 27.8mm
I love the idea of that thread!!!
I’m currently using a Basen in mine:
Just want a battery with higher capacity and known good performance.
Edit: I just messaged this morning Yass (supersports600) and waiting a response, those KP 6000’s are 20A continuous apparently.
So it should just fit then, that’s awesome to know, maybe those KP 6000’s are the new king of 26650’s?
The Emisar D4S can fit pretty wide cells. The main limitation is the length.
I don’t see why not. Emisar stated under 69 mm works.
The keeppower 6000 fit easily but keep going up in price at supersports600.
FedEx brought my new Samsung emitters…
Drumroll please…
My D4S with 4 Samsung LH351D W6 5700K emitters now makes a whopping 7348.5 lumens from a freshly charged LG HG6 20650 cell.
Edit: 21.6A at the tail… single cell record for me I think. 
Beamshot. .? Can you show the link where you ordered those led?
Samsung LH351D W6 5000K (I thought I’d ordered 5700K, these are nearly pure white though so I’m happy)
Hmmm, you must be pushing at least 8000 raw lumens, probably even 8400 lumens at start up.
What kind of cell are you using? Is it the darn Samsung 30T again?
You must be pushing easily 25A+, or about 28A. Are you using 18AWG spring bypass+direct brass contacts to the driver? That is one dope ass build.
If you can get 7300 lumens out of a single 21700 cell with 4xLH351Ds, I wonder what kind of brightness you could get with 4x18650s out of the Q8.
With W6 bin LEDs, maybe you could get close to 10k lumens out of the Q8 with BeCu springs, 18AWG wire bypasses, a pure copper tailcap, an AR lens, etc. Maybe just maybe, it is possible without resorting to barf tint fest XPL2s.
16’ from the fireplace, the room is semi dark but heck it’s 2:30 in the afternoon! lol
Moon, showing only in the glass face of the clock…
100% 7135 chip
Turbo
Taken with my i8 with an app running, essentially Aperture priority.
Edit: Here’s the specs on the above pics…
Moon used an aperture of f/1.8, with 1/4 second exposure and ISO 500.
Med used an aperture of f/1.8, with 1/7 second exposure and ISO 80.
Turbo used and aperture of f/1.8, with a 1/30 second exposure and ISO 32.
Blue, it’s the LG HG6 20650 cell, solder bump on the driver and your large spring with a 20ga bypass in the tail. 20Ga Teflon leads. 
The 30T will do 7624.5 lumens at 23.1A tail. This is using a 12ga solid wire to bridge the battery to tube, not assembled.
Oh, and these ARE W6 binned 5000K emitters, got em today and swapped em into my D4S within the hour.
Oh, yeah, just remembered, think about this… Anduril’s lightning mode with 7300 lumens!
Holy crap. That is some mad stuff. I would be scared to hold that power density in my hands.
In relation to this, story time!
As a few of you know, I have an MT09R. I had a brilliant idea of bringing the MT09R on a trip in my bag, along with a 20Ah USB battery pack. Note: I had not locked out the light. This is stupid.
When I was walking , I tripped, and fell down backwards. I was not hurt, but something was still wrong. I walked for about 30 seconds, until I noticed some massive smoke coming from the backpack.
IT WAS ON FIRE. I then remember I had a lithium ion battery pack inside of the backpack! I then quickly took it out, and killed the fire with water and a damp microfiber cloth. The smoke residue is still on the MT09R’s lens, as it is very hard to remove 100. I’m probably at 95 cleaned, but there is still some smoke on it. Luckily, the battery pack was just a bit warm, and nothing had blown.
TLDR: Always lock out your monster lights. Otherwise, bad things will happen because of Murphy’s law.
That sounds fun. 
Just be sure to warn people not to look directly at the light. It can give a false sense of safety when it’s rumbling along at a low level between big flashes.
Can barely even tell there’s a sun outside. You made it bright enough to overpower the daylight.
“Brighter than the Sun” … a new D4S tag line.
