TK's Emisar D4 review

[Jtm94]

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?

Does anyone know if there’s plans to make a similar light in a larger body with bigger reflector? Hopefully with added heat sinking people with delicate baby soft hands like me can use it without welding gloves on.

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…?

[noboneshotdog]

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

I sense a large drop in my rainy days fund in the next couple of months

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

[UserM4]

Wow! I was going to order a Convoy C8 but now I’m going to wait for this!

@jon_slider

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’m trying to build a callous and toughen up!

[peabody]

Dang Wang! Another must have.

[harry218]

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?

[Agro]

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

@Hank Wang

Probably in the middle of the month towards the end of the month, D1S will follow soon.

Man count me in for 1 and for D7 too

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?

[Jtm94]

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.

D1S??
