Welcome to BLF btw. Nice that there are more and more dutchmen on the forum Smile

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

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 8×7135 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&ssPage...

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.

"Whoa that's a bright light!" ... Yea I guess.

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 8×7135 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 8×7135 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 8×7135 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. Sad

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.

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 Wink 

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 Silly  )

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.

I don't know about these, but the common dutch windmill is brown (covered in reed) and not reflective, apart from the blades, they aere mostly white

Ah yes. The Dutch. I was of course referring to electricity producing wind turbines as they are mostly seen in Denmark. Sorry.

LOL, I guess that I am so dutch that I only thought of traditional windmills. Now I see that it makes more sense if gravityZ referred to modern windmills Smile

need help pls…

i tried to get the pill out
like the first time when i got the light and lubed the sealing:
unscrew teh bezel, use needle nose pliers and turn
that was easy then

but today… lets say: if i had a swear jar i had to put a lot in…

the pill does not move.
in no direction (should be counterclockwise to get it out – right?)

any ideas?
could it be that the pill got a “bump” from the head when screwed out while zooming?
i will try the heatgun tomorrow…

-> i did not play more than 5 minutes since i got it Sad

PLEASE NOTE
i do not work in "reviews, deals and codes" for the time being
maybe M4D M4X will return one day, but until then:

Both of the pills in my 1405 screwed out easily clockwise.

BINGO! it is open!

i tried cw – but not hard enough…

thank you!

which resistor did you pigyback to get which Amps?
-> i read 0,85 A stock

For one light I stacked 2 r150s on top of the r120 to get 2.6 at the tail from 1A stock. For the other one I swapped out the driver for a nanjg at 3A but more will be stacked to 5A

the windmills indeed are grey and used to generate power.
i do not think they are replective but since they are grey they will stand out the background more easily then other objects.

having said that i still the UF-1405 is superior because of the big lense.
i gave an exact same setup(8×7135 driver, xp-g2 dedomed, 1× 18650) in another zoomie with a 35mm lense. that one could barely light up the first windmill at 1270 meters and did not reach the others. so if that light is not able to do the job then a zoommie with a smaller lense or aa batteries is definately not going to reach it.

give me some time to should some photo’s
i will wait for ideal conditions and try to shoot a photo while lighting up the windmill.
last night had a clear sky but also a full moon which is not very good for contrast

Amsterdam is to crowded to place any windmills(maybee on the outskirts)

if you drive to Schagen/Den Helder however you will see lots of windmills along the way

as long as they are not to close to my home i like them

Im late to the party. Been too busy with other lights the last weeks/months so my 1405 have mostly collected dust. I decided to do a simple budget mod instead of bringing out the full potential of the light.

Total cost of my light with mod: 31,15$. (or at least below 32$) Throw 457kcd. (or over 500kcd with very high calibration)

Longest throwing light in that price range in the history of BLF?

Feel free to add an additional 7-14% to my kcd number to get closer to the highest readings meters.  (That means 500+kcd). Ive measured my light twice at 15m and once at 5m, after 30 sec.

Not bad throw for the price. Not bad at all..

Well done! Of course I would like to know which emitter, driver etc. And what you consider to be the full potential. You are being a bit too concise here, RaceR !

I botched the dedome on this XP-G2 S2 2B |( but it still gets 422kcd measured at 10m from 2 stacked R150s 3.6A at tail.
I need more practice with the heat method.


There was no tint shift as far as I could tell from dome on to dome off.

Here’s the one with the 3A Nanjg 1A dedome next to stock 439kcd.
