TK's Emisar D4 review

That’s a nice looking setup. Is that innertube? I take it you bite that light… :laughing:

Yep, the Nichia will be the floodiest under the stock (10622) TIR. However, I think it can vary with specific LED/TIR combos.
Some emitters can perform differently and be more or less floody depending on the specific TIR being used.
If you look at the Carclo website, it looks like the XP-G2 is actually the more floody option with a 10623 optic (or rather, still a narrower hot-spot than the Nichia, but with more spill).
That said, if you are looking for max flood, I’d go with the floodiest TIR optic (10624), and find out which emitter gives the best performance under it. YMMV.

It’s extremely floody with a frosted optic. Also very smooth. But on mine, I switched back to a clear optic because it seemed too floody for outdoor use. I kept having to turn it up pretty high even for just taking a walk.

Watched a YouTube vid and did a google search and some say that the XP-L 3A is probably the best usable led with the 10623 optic. Can anyone here confirm that’s a good usable outside combo?

I have a D4 with 2 XP-L 3A and two XP-L 5D with the 10622 optic. I love it. My wife and I just returned from a long walk this evening in the local open space. Plenty of floody light to light our path, but still decent throw when you need it so light up the owls flying in the distance (short turbo bursts). I don’t have the 10623 optic to compare. I imagine it comes down to personal preference, maybe buy both?

Some discussion of the two optics here

I’m not a great photographer, but d_t_a requested some beam shots of the 2 xpl-hi V2 3A and 2 xpl-hi V2 5D D4 I have. I am going to compare it to my nichia 219C light, which is the other D4 I have.

Both lights started up “fresh”, so presumably at full current in on 7135. I am surprised to see how green the xpl-hi light looks, as it does not look that way with my eyes. I am just using my cell phone. xpl-hi on left, 291C on right.

Now at the minimum of the ramp

and looking directly into the light with both on low, 291C on top, xpl-hi on bottom

I like the more focused light of the xpl-hi in this light. Both versions are very floody, but the xpl-hi certainly give better throw between the two. I prefer the color of the xpl-hi in person also. It seems warmer to me, at least in person.

I’m a D4 owner. It’s a perfect flashlight, but I’d like a D4S with 21700 batteries so I could also use all my 18650’s and still be small enought for EDC.

Question for TK: having just (finally) upgraded from my beloved A6s to the D4 I find myself badly missing the turn on at moonlight. I gather it was available in the first iteration of the UI, but was lost in the second. The only thing I have found requires ramping down before turning off the light, and I think I have sometimes mis-clicked and ended up blasting unintentionally. Any workarounds? Any way to “memorize” one level as the default? And thank you for all your contributions here (as well as your occasionally raunchy humor…)

Turn on at moonlight is still the long-press shortcut right?

Didn’t know they changed D4 fw, but my D4S will only memorize a ramped-to mode for the quick-click turn-on level. IDK if I prefer it or not. Not memorizing turbo, definitely, but I’m split on memorizing moon. Still, shortcut is always there, and natural to a long-time ZL fan.

Thanks, it helped. I wasn’t aware of the long-press and I still can’t really get it to ml since it ramps so quickly, but it helps to get it going on low instead of last-used. Thanks.

Sorry for late reply, That was when I just finished it. The shrink tube on clip has warn off, and I have lost 2 of the 5 magnets that where epoxied onto clip. It will still stick to the fridge. The inner tube can be rolled up to form a tacticool ring. Mouth holding happens :slight_smile: The inner tube also helps with grip when I have wet hands. I consider this one of 2 Convoy keeper lights. The other is M2.

BOT. I bought and tried the mteletronics clip. It works ehhh, most of the time. I did loose it once. D4 ended up in my pocket and I felt the clip poking me.
I just found my armytek clip stash. Don’t know what this came off of, but its much bigger then the Wizard clips I have.

Now what about magnets?

I have been seriously considering epoxying a neodymium magnet to the end of my D4, but after carrying it for several months there have not been a lot of times I would have used it. Perhaps someday . . . Also would want to know what the appropriate epoxy / attachment type material would be to get it right the first time.

I have done ok with 5 and 30 minute epoxy. I am looking for disk magnet same diameter with maybe a hole in center.

I have a disk with a hole, but smaller diameter than the bottom. I can see where same diameter would be nice, as it would not reduce the stability of tail standing.

From the Abstract —- with my additions….

The study results indicate that LED blue-light exposure poses a great risk of retinal injury in awake, task-oriented rod-dominant animals. The wavelength-dependent effect should be considered carefully when switching to LED lighting applications …. when you buy torches for your army of working rats. :student:

Not sure what that has to do with Emisar flashlights, since the 30s the D4 will stay on turbo only presents a risk if you point it at your face. Does make me feel good about preferring warmer tints like the 4000k XPG in my D4, 4000k XPL in D4S, and the new oddball Nichia 219D in the Folomov 18650S. I don’t know anything about the D, but wonder if it could handle D4/D4S currents better than the C. The Folomov seems to be putting 5A-ish through it.

3000-4000K definitely blunts that blue peak, 4500 on up it still dominates (some guesswork, the bins on Cree’s graph are really wide)

Any ideas whether the XP-L HD emitter offered in the D4S will find its way into the D4 lineup?

The XPL HD doesn’t fit the optics of the D4. Never heard of an HP-L.
