Uniquefire UF-1405 - A worthy zoomy?

[Ledsmoke]

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 :-)

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

[Chazzy]

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

[M4D_M4X]

clockwise??

[Chazzy]

Yea it’s reverse threaded.

[M4D_M4X]

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

[Chazzy]

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

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 )

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(8x7135 driver, xp-g2 dedomed, 1x 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

are you talking about the stock driver ?

[RaceR86]

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 !

[bibihang]

Yeah, I would like to know about the details too!

Yes indeed.

[Chazzy]

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.

Hi Chazzy, your mod is interesting but there are something I don’t understand about.

Assuming the stock driver delivers 1.60A to the emitter before modded. By stacking two R150 on top of the R120 it should give you about 4.16A to the emitter (neglect the losses) isn’t it? If you measured 3.60A at tail that would be translated into a whopping 6A to the emitter!

@Chazzy

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

In your case 3.0A + dedomed XP-G2 S2 2B = 439kcd

In my case 3.5A + dedomed XP-G2 S2 2B = 310kcd only

That is almost 30% of difference. I used my HS1010 to measure and convert the reading from 4.5 meters. May I know at what distance did you measure the lux reading?

[luminarium_iaculator]

100 members=100 different lux meters=100 different readings

So be sure that maybe your 310KCD would show 450kcd in some other lux meter :)

[bibihang]

Yes I am aware of that. But do we still call 30% of difference as error? Sorry I have never compared my lux readings with a lot of people before so I don’t know how much of difference would one consider as error.

[M4D_M4X]

I have a XP-G2 on noctigon coming from Hank…

can I use the stock driver?
if yes - which values did you stack on the sense resistors?
