Uniquefire UF-1405 - A worthy zoomy?

Wow, that will be as close to a laser that a flashlight can get :bigsmile: Let me do the calculation: in my UF-T20 that dedomed xp-e2 at 2.4A did 125kcd, the surface area of the 1405 divided by the surface area of the T20 is 3.75, 125kcd x 3.75 = 470. But usually when you get bigger you loose some, so perhaps 420kcd?

I love white laser, they are intimidating to people. :bigsmile:

And if there is a good 17mm buck driver available later I can always swap them again. By the way what is the maximum current can one XP-E2 take?

I really hope I can hit the 400kcd realm, but 300kcd would make me happy already. Can you set your 1405 mod in the top priority among your other modding projects djozz? Can’t wait to see what kind of result you can get with it! :smiley:

XP-E2 results are in my Luxeon Z thread (https://budgetlightforum.com/t/-/23773) max is around 2.5A, but personally I would not bother going over 2A, with 95% of max output.

I will mod this light with a XM-L2, it will have less throw than a XP-E2. I am not sure I have much time soon.

Ok, I started the mod..

I am going to build a new integrating sphere, but I am a bit hesitant because of the amount of work, so it was easy to postpone that for this :bigsmile:

I went for the 1x26650 chop. Complicating was that I unexpectedly found that the wall thickness of the battery tube was way thinner than the UF-1406 (mod of the UF-1406 is in this thread), so the fixing trick with the nails was not possible. So I went in search of a sock instead, and looking through my junk I came across an old steel high pressure mercury lamp cover that was waiting in a drawer for this mod since 1998. It was a tiny bit too tight, so perfect for this purpose :-) . I cut a ring off and sanded the inside smooth (there was a tiny weld ridge sticking out). I chopped the battery tube of the flashlight and sanded the anodising off the two remaining tube pieces where the sock would go.

Top: tail piece of battery tube, steel sock, top piece of battery tube. Bottom: remains of the lamp cover, middle section of the UF-1405 battery tube, middle section of the UF-1406 battery tube.

The sock was so tight that it could only be hammered in (with a piece of wood between hammer and workpiece). I used Arctic Alumina Adhesive to glue it as well, also good for waterproofing. It worked very well, extremely nice and tight, this will never come apart! I covered the intact ano with masking tape, sanded the surface, gave the surface a few layers of matt black heater paint and heated the tube mildly with a blow torch to harden the paint (and not destroy the adhesive or anodisation).

I also modded the tail of the flashlight with a new 6A rated switch, the same way as my UF-1406 mod.

So here's another shorty, first zoomed in:

You think that looks funny? How about zoomed out? :party:

The light still works the same as the stock light, so the next phase is the driver/emitter work one of the coming days. Hang on!

You did it again djozz!! :smiley:

The light when zomming out looks cute! It’s cute, but manage to throw a serious distance!!

^ Very sweet mod there djozz. Looks great!

You said:

. . . and looking through my junk I came across an old steel high pressure mercury lamp cover that was waiting in a drawer for this mod since 1998.

I imagine many of us modders have a nice "junk" collection. Glad I'm not alone.

I tossed 90% of my junk away when I moved house in 2008 because the new house had way less storage space (and my girlfriend moved in ). The 10% that was kept was the best quality stuff, but it happens very regularly that I need a piece of something that I don't have anymore :-(

no one ? i will receive this flashlight…. can’t wait to try it!!! comparing to the 1406 version ( 18650) this does have a larger HEAD/ OPTIC …. so the 1405 should be one of the best thrower ever? i think it is a reconrd thrower but i could be wrong

Got the light the other day. Switch issues on mine. Not impressive output stock. Its got potential though. :)

Sweet mod Djozz, once again. :) Nice seeing them side by side..

In stock form with the old XM-L driven at only 1.6A would probably give you about 500 lumens. And with aspherical lens you need to reduce another… say 20% even in full-flood (depends on how far it can zoom in), so you have about 400 OTF lumens if you are lucky. Throw wise I would estimate 60~70kcd with this kind of setup. Definitely not impressive by looking at the stock output but it has good potential to be modded and becomes a sick thrower.

I got one coming in hopefully by next week, and I’m gonna turn it into a white laser lol.

I think you are completely right here, I could not measure lumens because the head is too large for the entrance of my integrating sphere, but the output compares very well to my modded UF-T20 that puts out 450 lumen when zoomed out. I have also not measured throw but looking at the intensity compared to other lights 60/70 kcd also sounds about correct. In general for such a big light I would want both more lumens and throw coming out of it, in stock form the balance is not right. What should make people buy this light is the (for a budget light) unprecedented modding potential of 400+ kcd throw.

Everything above is just my guesstimation, I hope I’m not too far off. :smiley:

Driver is the real bottleneck in modding this light, but if we manage to buy it with Gearbest discounted price ($27), plus XP-E2/XP-G2 on Noctigon, 17mm driver (be it Nanjg or LD-40) we will have a 300~400kcd kick-butt thrower at under $40!

I finally got a 1405 on the way (replacement for my unusable Courui)! cant wait, I’ll either be cutting it down for single cell or using a heavily modded driver based on the LD-29 with an XP-E2 @ 2.6A (as a toy [“white laser], not a usable carry light)

man i cant wait to get mine, thx djozz for sharing this with us and i may cut mine just like you did but i will machine it , well any soon beam shots ?

Actually I'm waiting for a batch of springs, I am having them made and if they are good I will try them out in this mod. Should be within a week.

One question please, for maximum throw what would be better, an xp-e2 at 2.5A or an xp-g2 at 4.75A?

Thanks.

Obviously you have a good idea about it, at these currents the two leds have a very similar and maximum surface brightness, so throw would also be very similar. That said, for my UF-T20 I have a dedomedxpg2-pill(3A) and a dedomed xpe2-pill(2.4A), and the throw of the xpe2 is just a bit more, but the xpe2 led was cool white and the xpg2 led was neutral.

I remember a while ago I did a post about this, wait....found it:

Thank you very much Djozz.
So I’m going to try the xp-g2 for this flashlight (anyway, I don’t have an xp-e2).
Just another question from that emitters photo, did you test the dedomed xr-e?
I also have one from a long term stand-by mod and haven’t use it yet.

Don't bother with xre (even if ez 900)... Although it is far easiest emitter for de dome (pry off with pliers). XP emitters kills that old sucker in performance.

Djozz is legend. Looking forward for results.

Yes, I know what do you mean, but xr-e die is so small that at 2A maybe it could outperform the xp-e2.
That would be great for small cell lights.
