TK's Emisar D4 review

I’d buy asap if hank released a new tailcap with removable magnet and lanyard hole

I’m not convinced the D7 is a flooder. The DQG has seven emitters from a single 26650, so from a thicker triple 18650 you have significantly more space in the head. I can’t imagine the individual optics just placed further apart.
It would be more interesting to have larger reflectors, so probably metal reflectors instead of optics as losses would be high with the latter? With these larger reflectors, the light would move away from the typical flooder beam we’ve seen from the M43 and D7, and have a much higher lux/lumen ratio. So in terms of beam profile, it would be something between a flooder and a thrower, something comparable to an L6 or Q8?
A pure flooder would make the D7, although perfectly executed no doubt, just “another flooder” in a slightly different form factor. But this light could be a game changer… Just my thought I had for a while… :partying_face:

I really would like to see the introduction of a shortcut to maximum sustainable level in the next release of firmware. Maybe even make it a selflearning function, based upon the max temp setting and real use of the flashlight (with the particular LED:s and cell).

I love my D4:s and will purchase the D1 and the D7 when available.
Lanyard hole and optional real high CRI versions would make my day.

DQG Tiny 26650 3th has 33 mm head diameter. This is enough for a TIR with individual lenses of a size similar to Carclo 10 mm ones, like in D4. I don’t know what the lens size actually is there or what lens is it. I tried to find the manufacturer, without success.
D7 body size is going to be like 42-43 mm in diameter. With a somewhat larger head, it’s going to fit a TIR with 16 mm cups. This is enough for 10 cd/lm with a good lens. I guess with a perfect lens this could be beaten somewhat. Use of a floodier lens wouldn’t surprise me either. Somewhat larger head (and thus lens) is possible too. Anyway, I don’t view D7 as anything but a flooder, though I do expect it to be somewhat throwier than D4.
ADDED:
Forgot to mention, throw figures above assume XP-L HI.

Always leave them wanting more…

Thanks for the figures Agro. With increasing reflector and head size, so does the lux/lumen ratio. I’m more interested in lux value of the D7 than amount of lumens.

Just wanted to add: Q8 is a little under 10 cd/lm. So D7 may actually be slightly throwier and in general is likely to be in the same ballpark (as long as you pick it with XP-L HI).

Thrunite Mini TN30 (2016) has 7.1 lux/lumen and only 3660 lumens, and I find this light “pretty throwy” for a soda can light. With higher lux/lumen value, you need less lumens for a satisfying experience… :sunglasses:

i think the D4 should have been using D1 head to sink more heat and D1 should be using a smaller D4 head, D1 with D4 head and XPL Hi should give enough throw i think.

I’ve had every one of them and here is my list from best to worst according to my eyes and I’ve had multiples of them, not just one of each:

1) XP-G2 4000k
2) XP-G2 5000k
3) XP-L 5000k
4) Nichia 219c 5000k

I got my Emisar D4 XP-G a few days ago and I am really impressed with this little powerhouse flashlight! It lights up my entire backyard with perfect cool white light. This is my first light with ramping. Very cool! I love this light! The only drawback is it gets pretty hot. I’m gonna buy a few for gifts that will really impress the recipients. Good job on the design and build of this impressive light! :+1:

Too late to re-design a slightly more recessed button?

I’m surprised you would put a 4000K Cree as best looking pure white. Almost every Cree I have seen below 4500 is noticeably yellow.

Does any of you guys know if the mcpcb below is a direct replacement for the D4 board? The description says it’s 2mm thick.

Do you have all 4 of these to compare? He also mentioned rosy was fine. The XP-G2 4000k meets that.

It’s the same MCPCB , I think he advertised the MCPBS’s before the D4. I have one running a quad Nichia :

Geuzzz, that looks like the same Noctigon board that came in my D4. I’ve replaced it with Richards quad board and Nichia 319AT emitters.

Thanks guys! Ordered.

How about the other xp-g2 and xp-l tint? I’m curious as to how you would rank them.

I don’t do tints above 5000k (unless extreme circumstances and a modification is planned). So I only experienced those 4.
