Uniquefire UF-1405 - A worthy zoomy?

Make sure to keep an eye on driver diameter, you only have so much space

can someone tell me if the UF-1405 pill is the same as the uf-1406?

I have a 1406 torch and just disassembled it and took a look at the Pill and the pill is really easy to mod for a 20mm driver, have the space and like I said it’s easy…

I’ll try to get a piece of cooper and machine a new custom pill for these torches… I’m really excited on this now XD you guys are making me an addict on this already XD

I guess I have to stop reading this forum… ahahahha

Can anyone tell me the o-ring setup for the lens of this light? Just got mine yesterday and the lens rattles and moves enough it changes the beam profile, there has to be something in there to hold the lens tight right? If not is everyone just living with it or what? I'm just trying to figure out what I can find to work best cause I dont have any on hand that large. I'm thinking I'll have to cut a gasket out of a sheet of neoprene for best results unless I can find exact measurements of the o-ring.

Edit: found a 1.2mm thick 67mm o-ring at TSC that fit perfect but if I can find thinner 67mm rings I'd like to put one above and below the lens to help shock isolate it more, the edges are already starting to chip. Maybe I'll still cut out gasket's to do that.

hey guys,
hoping for a little info regarding moding the uf 1405
I am looking to mod my first flashlight…(sorry ) and had some questions
in an atempt to keep this on a mid skill level range in my reserch i have an idea you guys are on the right track w the xp-g2.

Q1.in order to install an xp-g2 s2 1a is it nessary to use a single battery 18650 w spacer or can i use the 2 26650s i intend on buying w it…?

Q2. in order to install an xp-g2 s2 1a is it nessary to install a nanjg driver…?

Q3. in order to install an xp-g2 s2 1a is it possable to just do the add the resistor mod in loo of the nanjg driver

Q4. in order to install an xpg2 s2 1a is anything else req that im missing?

Q5. is heat sink and pill the same thing

Q6. where is a good you tube link / info to learn more regarding moding (this flashlight lol ) for dumbies

thanks for your time
jeff

well I’m far from an expert (actually I’m a noob but anyway) I’m watching this thread also so…

A1 - you can install whatever LED you like then just have to use an adequate driver (for whatever Amps you want and according to 1 or 2 batteries). the stock pill acept’s 17mm drivers only, IF the pill is the same on the UF-1406 then it’s possible to either mod the pill for using with 20mm drivers or even a bit more, again IF it’s the same pill as the 1406, that’s an information that I’m still waiting for confirmation

A2 - as far as I know (I’m completelly guessing here but…) all nanjg drivers are AMC7135 (these are Amps regulators only, each one will limit 350 or 380mA passing through them, so if you parallel 2 of them they’ll only let 700mA pass [or 760 if they are 380mA ones] and work only from 2.5 to 6V so can’t work on 2 18650 or 26650) based so they are single cells only (because on majority of LEDs their Vf it’s on the 3-4V so there’s no need to conver voltage from 1 battery to these values). Like I said I’m not sure here but one thing I’m sure, never seen nanjg drivers that weren’t AMC7135 based.

A3 - Here again I can’t be absolutely sure but according to my previous answer, AMC7135 based drivers don’t use the sense resistor so no resistor Mods on these drivers.

A4 - that’s an non sense question because you can install any LED you like, the problem is to get a griver that match the specs you need/want

A5 - heat sink it’s the zone on the flashlight tube where the pill screws and will dissipate the heat generated by the electronics, the pill is where the LED and driver are installed.

A6 - not that i know off.

regards hope it helped

thanks for the sharing your knowledge on this subject …. I am hooked on researching this light . If any one else has anything to add please feel free to post.
cool hobbie )
thanks

Received the light form dealsmachine(took 3 weeks)

i must say the quality is amazing.
threads are lubed, no rattling.

I lubed the o ring’s which hold the lens in place just to make sure.
also lubed the o ring of the tailcap and the one which slides inside the lens holder

indeed i got .9amps when loaded with 2 18650’s so the standard driver has to go.

i got rid of the driver and led
installed a 8x7135 driver and a dedomed XP-G2 on sinkpad

will test it tonight but comparing it to my other 35mm lense flashlight with same setup the hotspot is twice as small but way brighter.
this should result in a throw beyond 2KM(got 1.3KM with my other light.)

i used this driver
http://www.ebay.com/itm/301225726107?\_trksid=p2059210.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

Welcome to BLF btw. Nice that there are more and more dutchmen on the forum :-)

Nice mod!, I'm curious what throw you will find! Am I correct that 2km throw equals to 1000kcd? In that case you will not get there, more probably between 350 and 400 kcd (1.18-1.26 km throw)

on my horizon there are a couple of windmills.
i can light up one of them with my old light and it is approx 1.26km away when i use google maps to measure the distance.

it barely lights up but no hotspot.

as soon as i can do some testing with the uf-1405 i will post the results.

for now i will get a 26650 cell and a spacer cell to make it more solid

Wow I did the exact same thing and got ~12.2kcd at 6m after 30s

I’ll stack 5 or 6 more chips to try and break 500kcd.

despite the desciption the driver I mentioned does not have low voltage alarm.

the seller i bought it from wants me to send it back.
I do not think this will help because I suspect the whole batch of drivers does not have low voltage alarm.

I ended up buying a more expensive 17mm 8x7135 driver($10) which hopefully does have the low voltage alarm as promised.

Do you mean its stock driver does not have low voltage warning?

And you bought one piece of 8x7135 Nanjg driver at $10? That is very expensive and may I know where did you buy it from?

The stock driver in my light. Which is probably the same as the one in yours and most others have good current regulation (about 1,8A to the emitter) when input voltage is from 8,4V and far below 5V. I did not see any low voltage warning or cut off. It could easily drain unprotected cells below 2V without the user noticing. I would certainly recommend protected cells with that driver.

i replaced the stockdriver with a 8x7135 driver to make sure i get 3 amps to the led.

indeed the nanjg driver is not that expensive ($3 at fasttech)but the type i bought has a bit better finishing and a better spring.

i bought a 20mm version and i like it a lot
because of the bad exerience with a driver without low voltage warning i wanted to make sure i got something OTHER then a nanjg

i will use the 7135 from the other driver to boost the one i bought to 4 amps

this is the one i bought of ebay(yes it is expensive but quality looks similar to what i bought before and that one was really good.)

At last i have received my light my 1st zoomy it is well made ( built ) big head with big glass lens i like it soo much it feels good in the hands

about its driver i think it can’t be resistor modded right ?

I put in a modded LD-40 with an R120 stacked on top of the original R100 resistor and 340kcd is the best I could get with dedomed XP-G2 S2 2B. :frowning:

Current measured at tail is 2.60A with two 18650, that translate to 4.30A to the LED by estimation. I have modes problem with the LD-40 when using two 18650, may or may not fix it though.

did some testing tonight to see how far it would reach

i have 3 windmills at my horizon

windmill at 1270 meters, no problem, lights up in the dark sky
windmill at 1380 meters, no problem, lights up in the dark sky
windmill at 1610 meters, does not light up in the dark sky

so with a fully charged 18650 IMR and 3 amps to the XP-G2 led the range is about 1400 meters i guess.

do not know the light intensity but in the end range is what counts.

do you have pictures from that comparison?

To those who are doubtfull of the range spotting of windmills I'll just add a few observations.

Windmills are oftenmost whitish/light grey.

They are slightly reflective due to this. The ANSI standard limit of vision (0,25 cd) is based on a non reflective surface. Removing this limitation makes almost any light have endless range as you could theoretically set up a perfect mirror the size of a barn to make sure your single aaa light had a 3 km range ;-)

I have spotted windmills at 900 meters with a ~35 kCd light (kCd measured by myself later).

Due to having no spill at all zoomie lights do not reduce your night vision as much as reflectored lights do as the "backscattered" light from the spill of a reflectored light plays heavily on your eyes. Especially high powered ones (lights that is. My Eyes do not require external power :-p )

My modded LD-40 is pushing >4A to the dedomed XP-G2 and it only give me 340kcd, that translates into 1166 meters.

There is no large open space or buildings from very far away to aim my light at around here.
