TK's Emisar D4 review

Hank, any new ETA? The last one expires today.

I’m speaking about the turbo shortcut which preserves the memory of the ramped level while the light is on. You don’t lose memory of the ramped mode until you turn it off if you double click to get to turbo.

If I ramp it up halfway, use it there for a while & then double tap to get to tubo, I can then double tap from turbo to get back to the level I had ramped to (in this case, halfway). If I turn it off in turbo after using thatdfouble tap shortcut, that half way point is no longer in memory so double clicking from turbo after turning the light back on does nothing. I’m not saying the light shouldn’t turn back on in turbo, just that the memory of the last ramped mode be preserved if it’s turned off from the shortcut. It seems like this may be a bug since I can’t think of any reason why this inconsistent double tap behavior would be deliberate.

Obviously remembering to double ta out of turbo back to the ramped mode allows you to preserve that memory but I don’t see any reason why you should need to remember to do that.

Oh, Hank did the D1, the thrower version?

Just realized I misread some of what firelight wrote. While I agree with his/her qualm about losing the ramped memory, I would still like the light to turn back on in whatever the last mode was (turbo even if you double clicked for turbo, etc). I don’t see why you lose memory of where it had been ramped after turning it off from the turbo shortcut.

I love setting a lower ramped level and being able to double click between that at and turbo. I have to remember to double tap to switch from turbo back to the saved ramp level before turning it off or I lose what I had saved and have to set it again once I turn the light back on.

Nice Hank!

Gotta buy yet another light now, it seems… :wink:

It could always be worse, you could have a mayor that insists that no matter what the governor nor FEMA nor NWS says about evacuating in front of a massive and slow moving hurricane, that you stay home and off the roads. I guess it’s safer to have to swim to higher ground (if your not disabled)(and you can swim) and wait someone else to evacuate you. There are a lot of hungry, thirsty, sand wet folks in Houston, but I doubt the mayor is.

I haven’t really kept up with this huge discussion, so if this is already well known information then I apologize for the double, but if you’re still looking for a clip option for this light check out this Overready. Yeah it may be a bit silly to put a $25 clip on a $40 light, but I think the D4 is worth it :slight_smile: I did have to dremel it out just a bit inside; its slightly too narrow from the box, not too hard though. Also a spacer is required inside so the tailcap contacts the battery tube. A paperclip works well, if you don’t want to get too fancy with it. I’m sure there’s other ‘universal’ ~1” clips out there that would work too. I personally like this a lot better than a friction-fit clip.

Could you possibly measure from the bottom flat to the end of that first cut-out? I’d like to know if I could chop it down to fit the short tube D4… :slight_smile:

Edit: Looking for 0.82” or 20.9mm, can it do that?


Hmm, it may be a good idea if Hank looks at this picture, that clip looks very very good on the D4 :sunglasses:
As for the paperclip: I have an assortment of brass washers, with a hot solder iron you can solder a fitting one onto the tail PCB for a bit permanent solution of the shortened tail threading.

Yes it does, but USD 25:- for a clip is highway robbery.

Not exactly sure which measurement you’re looking for so let’s just do it this way. If this doesn’t answer your question just let me know and we’ll try something else :slight_smile:

I’ve got a roll of thick copper sheeting that I’ve used for various spacers and things before. If I wind up using this light as much as I expect to I’ll probably pull the tail apart and build the grounding ring up using some cut copper. The paperclip is doing the job right now though. :slight_smile:

No argument from me. But I guess I find them worth it because I’ve put these clips on lots of lights. I mean at least they’re steel now. Back when they were made of titanium they cost twice this much :smiley:

So, anyone know where to find the information on heat-cycling li-ion cells?

Let’s see … ’oogle … ’oogle …. aaah:

https://www.nature.com/articles/srep12967

Does anyone make a primary (disposable, non-rechargeable) cell in the 18650 size?

I tell ya, we’re in the process of reinventing the flashbulb here.

I’d like to see these super-bright emitters built to use separate from the battery carriers — bolt the bright/hot part instead onto a big handheld heatsink, and connect that to a belt-pack power supply with a big copper cable. Then we could wave around the brightest possible light source without killing attached batteries by heat cycling.

Regarding the clip. Someone mentioned the Solarforce clip works as well. May need to be reamed (I’m not sure). But, that one is $4.50.

I’m personally going to make an order for that one right now and give it a try.

Thank you. And yes, that does indeed answer the question. It could be made to work on the short tube…

I have a piece of sheet Titanium and may try my hand at making a clip, need one for a pocket knife as well, so…

There has been a few comments regarding the D4 UI…
Will there be an updated version on future lights - D1, D7…?

Fasttech has the Solarforce clip for $5.20.
I’ve seen it for anything from $6 to $20 for sale elsewhere.

Solarforce used to make a nice deep carry clip but I haven’t seen that for a few years.
A guy was going to make something similar, but he disappeared: http://www.candlepowerforums.com/vb/showthread.php?381284-Copperhead-Deep-Carry-Clip

Unfortunately it looks like FastTech stock on the solarforce clip is discontinued.

I don’t think it would be a good idea.
The UI has a lot of things that you can make, and if you have 3 light with all different modes, you will get confused a lot.

I would love if the driver from the D4 would be free to buy…
That UI on a 12*XP-G2 King or so…

[quote=L4M4]

Updates should be done and a system/service put in place to update the drivers on previous lights if desired. I have about 35 flashlights with different UIs at home. We can handle an updated UI. :slight_smile:

Only 35?
pfff n00b :smiley:
I don’t have a problem with different UIs, but if UIs are 95% similar, you will get confused about which UI you have right now.
Also, I think the UI is really good. Most of the time you just need the ramping or the double-click 100% mode.
