Uniquefire UF-1405 - A worthy zoomy?

Hmm… I can’t think of any good source to read about the collimation things at the moment. My very limited knowledge was gained from reading different threads and discussions here in BLF and playing around with different sizes of lens.

This thread has some photos and illustrations constructed by the OP. Maybe you can visualize something from there?
Dr. Jones’s thread is less related to your question but more about the dedome phenomenon. Anyway it is still a good read though. It is very informative.

Maybe other members can chime in and help. :slight_smile:

Hi friend,

I will give an example of different 50mm lenses (left tablo A9 right Dereelight Nightmaster) and my observations on them:

- They both have same die projection, but left lenses has cleaner die image

- Right lenses have about 15% more throw but they also have much less flood when zoomed out than left lens

Left lenses: clear die projection, and very good flood mode

Right lenses: fuzzier die projection but more throw, and very weak flood mode

Mystery to solve why left lenses have less throw than Right one?

Same thing happens with goread a2 50mm lenses which are even lower profile than left(tiablo) lenses on picture, and goread lenses give excellent die projection, even better flood mode but still much less throw then right lenses on picture, and now less throw than left(tiablo)lenses.

So conclusion here from my redneck testing method(all lenses tested in same host but I had to use different distances from emitter) is that lenses with lower profile, or lower height will have less throw but clearer die projection and the better flood mode than the one with longer profile.

Dereelight lenses beat all mention lenses of same diameter but with terrible flood mode comparing to other ones.

I want to say Bibihang that candela difference of right lenses is 15% more throw on left(tiablo) lenses and 25% more throw on goread a2 lenses(short profile 50mm lens) so candela difference is very visible and they don't have same measurements as they supposed to have by your theory

Bibihang's explanation is not a theory, it is an explanation that need not to be proven, it is simple high school optics. (thanks btw, usually it is me who has to do that explanation ;-) )

That said, the simple lens theories do not include lens quality, it assumes perfect lenses. So if you find throw differences between lenses, it may also be a quality issue. Luminarium ejaculator has done testing on that.

When I hear name Djozz it immediate associate me to BLF. Djozz is BLF.

To continue testing... Forgot to say that right lenses can be put at shorter distance from emitter for best focus while left lenses need spacer and of course larger distance from emitter, and Goread a2 lenses needs 2 spacers and greater distance from emitter to achieve best focus.

Thank you both luminarium iaculator and djozz for helping out here. :slight_smile:

When I was talking about identical diameter of lenses will produce the exact same candela (throw) I was assuming everything else is same (including the lens quality) except the focal length - Sorry for not making it clear earlier.

Has anyone put an MTG2 into one of these as talked about early on in this thread? I would imagine that the throw would be lowered?

Wow! Did they actually see djozz’s mod earlier?

It is available in shorty version now!

Hey :Angry: !!!! :Wink:

This looks promising...

Wonder if protected 18650 fits inside this little monster.

For example in Goread A2 you can barely fit classic 18650 cell and protected no chance:

What do you think guys is this tight fit with unprotected cell or it got some space for protected 18650?

Looks tempting...

So now, with the improved switch and shorty version, this flashlight brings 400kcd in reach of even the clumpsiest/laziest budget flashlight modder!!! :-) :-)

So, yes, now the 1405 is a very very worthy zoomie!!

You should have patented your mod before. :smiley:

I have asked the sales rep in Alibaba and they told me they have not started mass producing this shorty version yet. They need to wait until some retailers (like FT, BG, GB…) make orders then only they will start producing this shorty version.

Did you notice that the shorty in your picture above is labeled 1504 instead of 1405? :lol:

Yes I forgot to mention that this shorty version is named as “1504” as shown in their website as well as on the head itself haha.

Yes the 1504 is the best bang for the buck thrower at the moment! But there is one annoying thing about the 1405 (and probably same with this 1504), that the focusing for maximum throw is out of position, did anyone else realize this? The lens was sitting too close with the LED, and I had to add a piece of wire under then o-ring to “raise” the position of the lens and now it is perfectly focused.

Lux reading of my modded 1405 before and after “raising” the lens:
Before: 310kcd
After 365kcd

That makes quite a lot of difference. I do believe this problem still does exist on the shorty version (1504).

Ask them to do a version with XM-L2 U2, a decent driver (at-least 3A on high) and without the cr*p battery. This version is only with IR LED.
Maybe we can get a group buy.

Wow O.o i should sell mine now and get that shorty :heart_eyes: ADDICTION WILL NEVER END :evil:

I will try to suggest them using high current driver or even better with Nanjg 105C driver, but I doubt they will listen to me.

I have already owned a 1405 too, so unless the price of this 1504 is really good and hard to pass up otherwise I don’t think I will buy the same light (literally) again.

I have contacted with someone from Uniquefire and suggested to make the new Uniquefire 1504 the new shorty one with an Anti reflection coating on the LENS, well they have responded 2 times

First they thought that i was talking about the flat lens that comes with reflector lights,

-

This is the first message they sent

Hi khaled ahmed,

Have a nice day!

The UF-1504 will be produced next month as you said,

The suggestion you gave mean that the lens will be the flat glass lens with reflector cup, not convex lens, is that right?

-

Then i explained and sent to them a pic for the JAX Z1 lens with the Anti reflection coating on it wothout sending the name of the light only a pic for the lens

They responded with the following

-

Hi khaled ahmed,

Ok, I will negotiate with production department about the change,

-

I hope they really make this light with the AR Lens

And i asked them to make XM-L2 version

good work here! So Uniquefire actually is people and a factory, not just a brand name to be used by any chinese trader?

truly a unique brand *badum-tss* :P

Well, this is quite tricky. I did chat with the Uniquefire sales rep in Skype many times before. If you contact the seller with the name “Shenzhen Homesafety” in Alibaba then I think yes, they are good manufacturer who has sales rep that answers inquiries.

But I still believe that there are other Uniquefire “clones” in China…
