TK's Emisar D4 review

Username DOESN’T check out :person_facepalming:

Yeah, not sure who that is, but it seems the account was created just to complain about the guy who runs Emisar.

What Hank said was probably correct, and is likely a useful answer. Sounds like something broke, and it’s one of two types of electrical shorts. It should be relatively easy to fix.

To add to the list of possible reasons a light would fail to respond to clicks and exit turbo mode, my friends D4 did the same thing after I accidentally popped off the R5 and R4 resistors while disassembling for an Anduril flash. We managed to get R5 back on, and we thought we got R4 back on as well, but it only looked like a good connection, actually it was open circuit.

With R4 essentially unpopulated, the light seemed to run fine, except it would not enter any strobe modes, and once you entered turbo, the only way to exit was to disconnect power. Very strange. According to zeroflow, “R4: MOSFET current-limit”. So this would seem to make sense?
Who knows. I fixed the connection properly and it’s back to normal now. Just thought I’d chime in with my experience.

Well, i couldnt find. But were there any torx screw? U sure remember!

d4buyer. Ok? Cant remember password.
unintended connection somewhere, allowing power to bypass the driver entirely. - how is it easy to fix? I am just an office worker, so i am trying to get answer, as hank is silent for over two months. Just got tired of nokia as a light.

“just an office worker”, we all started somewhere, the first step is to realize you aren’t “just” anything… your potential is unlimited. :wink:

Its good but no time

Tint mixing is so hot right now :sunglasses:

SST20 3000K and 4000K both 90+CRI

Ooh nice! I’ve been thinking of doing this, but with 3 4000k nichias, and one 3000k Nichia, just to bring it down a little. Thoughts?

Yeah, nice. Do you like it X3? I really like this sst-20s. I was thinking of 2 3000k and a 4000k if the FW3A is ready someday.

Seems to me it was ToyKeeper that started the tint mixing thing with her Terminator. :wink:

I also did it years ago with a ridiculous Quad XHP-50 set up in a Lucky Sun D80. Very neat look, had to keep it reduced using 2 18350’s as with 2 18650’s it’d make the light too hot to hold in mere seconds.

This bothers my OCD :laughing:

It’s nice and even though! Lol I like it

This was one mighty fine little light. Got mine today and I’ve played some with it. Only problem I see is that it ramps very quickly down from high levels since it get hot.

I also read a thread on laser forum where a guy got a 1watt laser into his eye and got permanent damage. This sounds really scary and I got to think of dangers with powerful flashlights like this and kids. Is it safe to let my kiddo use this? She’s 4 and really liked this little light, told here to not touch the button on it and use it at the level I set for now and I’m watching all the time. Am I paranoid?

No you shouldn’t give this light to kids. My daughter is 7 and is not allowed to play with my D4 and other hot rods.

I wouldn’t leave this light with my coworkers. There worse than kids.

Its the right size for a kid but has grandpa power. Must be respected.

My nephew is 4 and is not allowed to touch my D4. His father does not let him touch his D4 either. He has his own little AA LED light that he uses and feels like it’s the same as ours.

Too much potential damage to skin, eyes, furniture, etc, in my humble opinion.

I would do 2+2, I doubt that you would see a difference with only one 3000K in the herd.

I love it, SST20 have a small die so you gain some throw compared with 219C or worse, LH351D.
I’ve tested both, and the SST20 are my favorites, because of the gain in throw.
The tint mix is really nice, but I already like both tints so it’s not really a surprise :slight_smile:

Probably not. If she is an exceptionally cautious child, then maybe… but that would be pretty rare. Many adults can’t even use a D4 safely.

Start with something safer, and let her work her way up to more powerful items as she demonstrates she is responsible enough to use them.

Hmm, maybe not. I think I’m gonna try it though, mostly because I only have four Nichias to my name, 3 4000ks and a 3000k. There’s a fourth 4000k in my buddies H03 that I’m gonna swap for a LH351D next time I see him, but that won’t be for several weeks. I really want a nichia D4, the D4 was my first light that I got before I knew what tint I wanted, so it’s a 6500k xpl-hi, no gracias lol.
