There is indeed a thrower with a bigger reflector coming up next, from what I recall. Someone with a better memory will probably give more info and the name.

It’s most likely going to be a lot different in function though. Nothing like a floody quad.

have you tried lowering the Thermal Configuration to match your hands preference?
So many people are complaining about how hot the light gets, and it has a user configurable thermal sensor..
Why doesn’t anybody use it to make it not burn your hand?

I really like the 100% regulated output level. At around 150 lumens it’s approximately between levels 3(80 lumens) and 4(240 lumens) on my E2L, S2+, and BLF A6 which are my most used modes. I have 7 modes enabled on all of them counting moonlight the S2+ and E2L using Bistro.

I have a question about perceived brightness that came to me in my sleep. I understand that to double what the human eye perceives you need an exponential increase in light, but when using floody optics where the output is less dense, thus less bright to the human eye, does that even out the correlation between perceived brightness and lumens?

I hear there’s an Emisar D1S coming up soon. Hank estimated it has 120 kcd / 692 m of throw.

(And there you go, Zanflare F1 is off the to buy list.)

… Do we get to see some pictures of the D7 as well…? Smile

Shoot! Just take my money Hank! Looks like Emisar is going to be a staple in our collections gentlemen.

I’m quite interested in hearing more about the D7 too.

That’s such a great development Hank. I would also love to see the body with screw on pocket clip if possible.

Is that D7?
And are the tubes of those lights interchangable?

It’s D1. From memory, 40 kcd. It seems to use XP-L HI. Can’t wait. Smile
ADDED:
Confirmed, around 40 kcd. Will be available

Thanks for the info. I am wondering the classification of D1, D1S and D7, correct me if I am wrong,
So D1 is a small sized balanced light, not as much throw as C8,
and D1S is going to have a bit more throw than D1,
and D7 is going to be a flood light like D4, but with 7 emitters.
Are there any plans on other Dx?

Added a little DC FIX to mine and the partial squareness is almost entirely gone and it’s a tad bit floodier. My approximating shoebox doesn’t see any more light loss than whatever 1 of my “calibrated” lumens is worth at 100% 7135. I also tried melting/burning it off with repeated turbo runs with no failures. Now I can hold off from buying more optics for the time being.

I picture the D7 being very reminiscent of the DQG Tiny. As my anticipation heightens I’m hiding my credit card.

Yes, D1 and D4 tubes are interchangable, meaning D1 can also use the 18350 tube to become a tiny thrower.
D1 around 40Kcd, 1*XP-L HI, ultra small body, slightly bigger than D4 as it can be seen above, true all arounder for size and throw
D4 around 120Kcd,1*XP-L HI, excellent throw, small body

D7 is using 7*LED and 3*18650

Same UI on all D series from Emisar

I’d call D1 a pocket thrower. Less throwy than D8, but much smaller.
D1S is 110 kcd, so just a small thrower.
D7 has 7 emitters and 3 18650s, most likely very floody, though if they keep the styling (head significantly larger than body), it could be throwier than D4 (w.r.t. beam profile, not just intensity). I haven’t seen any pictures or written details, so this is a wild guess.
I’m not aware of any other Emisar lights in the pipeline. I’d love to see some zoomies. And 21700 battery tubes…

Added: Hank beat me to it. Smile

Hank, will D1S be available with 26650 tube?

I posted this recently over at the “What did you mod today” thread. Thought I should also post it here, since this is the D4 thread.

I went ahead and modded first custom firmware, for the Emisar D4.

Very simple stuff (not like I have the knowledge to do anything fancy). I just removed the mode memory, (Or rather, it always remembers the same level) and now, a single click will always take me to full 7135 power (125 lumens). This way, I always have access to moonlight (long press) medium (single click) and turbo (double click). And if I need any other mode, the ramping is still there, right after moonlight. Basically, I don’t like not being sure about what my flashlight will do once I press a button, so I dislike memory mode. So now, I have the best of ramping UI (being able to choose any specific brightness I want) and the advantages of discrete modes (easy to get to certain pre-defined levels).

Took a few tries, but luckily, my driver testing setup worked well enough.

I also changed the led leads from 22awg to 18awg. It had no effect on the output, according to my “approximating sphere”.

Now, I’m trying to find a way to remove the tailcap pcb, so I can place a magnet there. With some luck, a 1mm or 1.5mm magnet will have enough strength to hold the D4 up, which is the biggest magnet I figure will actually fit in there.

I asked the same question. It seems (did not look above Facepalm ) there is definitely a D7 coming 3×18650. My question is more of a DQG Tiny 26650 III size (but a little bit longer to avoid the issues shortness causes) so maybe with support they will go for a D? like we keep asking about?

Perhaps is the moment for add option for 20700 tube in next models….be prepared for the future….

I like the D1 and perhaps D1S!!

I epoxied a pretty thick and strong magnet to the outside of the tailcap. Not as clean looking as CRX’s magnet inside the tailcap, but it works for me.

I wonder how does D7 compare to Q8. Smaller, higher peak output, lower sustained output, floodier, costlier?
