TK's Emisar D18 review -- 3x18650 photon grenade

You’re probably right.

It’s a bad habit.

is there any chance to insert some strong and thin magnet to the tail? or am i an ignorant?

It would work, but you’d need a very strong one.

thanks for your quick answer. once i get the d18 i will measure the diameter and look for a magnet

Subbed

I got my D18 Monday and I was sure when I first tested it that top of ramp was not the same as turbo. However, after playing with it more last night I couldn’t notice any difference in brightness double clicking at top of ramp. Need to investigate if the ceiling is too high or if I managed to find some bug. Battery charge level should be 4.0+ but I will test that too. Is there some firmware version that was delivered with top of ramp = turbo?

Mine was set to top-of-ramp = turbo as delivered. I bumped the top-of-ramp down by about 15-20 clicks.

As mentioned in another thread, on smooth ramp mode, my ‘delivered today’ D18 SST-20 4000K with brand new button top VTC6 batteries also showed no visual difference between top of ramp and turbo. However, on stepped ramped mode, there was a noticeable difference between top of ramp and turbo. I like to have smooth ramp go from moonlight all the way to turbo, anyway, so i configured that way afterward, to ensure it was deftinely operating that way. Everything else seems sweet. Amazing light. Smaller than expected. First light with Anduril, so lightning mode and candle mode are pretty neat to play with, too. Also, it fits my Maxpedition Remora EDC bag nicely!

So do I click 50 or 51 times to set ceiling to max regulated?

51 times.

The first click is the highest level, 150. Second click is the second-highest, 149. And so on.

It may seem like it’s off by one, since level 140 of 150 is 11 clicks… but it’s because otherwise there would be no way to get the highest level. It’s like how the “first century” is from 0 to 99, the second century was 100 to 199, and the twentieth century is from 1900 to 1999.

Does anyone know which tint binning the 4000K SST-20’s Hanks uses have? I’m thinking about ordering a D18 without leds and putting 18 FD2s from BlueSword in it but it would be funny if it appears Hank uses the FD2 bin.

Judging by the ones he is selling for parts it should be FB4 bin. https://intl-outdoor.com/luminus-sst20-bare-led-p-936.html

D18 has FB4 and looks like this:
In my opinion, the color is really pretty and I do not see too much sense to fight for FD2. I will just add that the Duv 0.0010 does not change too much, because at 1000 Lm the measurement gave me the same value.

All the testing seems to indicate the SST-20 in the D18 is more inline with the FD2 than FB4 tint. You should email Hank directly.

Aux board successfully tested
Prototype had an error so the LVP chip does not work without rewiring

Looks a lot different above the TIRs. Pretty cool

Sweet!

:sunglasses: :+1:

Its seems that there is a little mistake on this protrotype with the AUX LEDs colors order on the external ring. It looks better like on the inner ring when yellow is placed between green and red. Pretty sure you already noticed it but worth mentionning to be sure.

its warm white not yellow, camera does not show it right

I just took a tint measurement at turbo and got this:
CCT: 4137K
DUV: –0.0024
CRI (Ra): 73.1
R9: –18.5
Rf: 70
Rg: 97
Ra: 73.1

5D is still one of my favorite tint. Looks very perfect neutral white at night time with no hint of yellow when my eyes are adjusted to the 2700K-3000K house lights.
