Liteflux LF2XT Discussion Thread (Part 5)

[Magnumpy]

has anyone else noticed this light behaving erratically when the battery is low? mine will spontaneously change modes and do all kinds of other silly hijinks when the battery is dying :duh2:

 

[Zeruel]

Mine didn't. I've killed an unprotected 10440 by using it till the light shut off by itself.... without the ODP on. No funny modes as you've experienced.

 

[Flying Turtle]

I have not noticed this kind of erratic behavior when the battery is low. Like some other problems I wonder if this is resulting from a loose switch.

Noticably brighter

With alkline nixx or li-ion?

With alkline nixx or li-ion?

Li-Ion in both flashlights

that could be, It happens so randomly I'm not sure exactly what the cause is. another possibility is that I'm just not used to the interface and misinterpreting things. something else that happens is when I push and hold the switch to scale down the brightness sometimes it will just turn off. I guess that does indicate a bad switch? :thinking:

Hey all wise n happy LF2XT owners!

Ive been having trouble tryin to decide on which light to upgrade to from my current EDC being a Proton Pro...the LF2XT or the Zebralight SC50w?

The pros for me:

More flexible UI/lower low vs Higher output/throw/runtime

Also i have quite a few unused LSD NiMH AAA which want to be used!

So i was wondering what light/s were replaced by the LF2XT as your EDC(or 1 of your edc's)

Thx!

 

[compasillo]

Transformed my black 2XT into a bare Al one

 

[KuKu427]

Nice!
Did you coat with something to protect against corrosion?

Not yet.

I think the oxidation will produce a natural transparent coating but
I'm open to your suggestions (I'm looking for homemade anodizing info...)

TiN!

LOL, but that works better on a light without knurling.

Oh, I had a bare Al proto, it showed some blemishes after I left it alone for some time. That's why I asked about what coating you are using.

These might be helpful.

I've also heard about ppl using car wax and Tuf Cloth...

 

[TooManyGizmos]

Yeah ... oxidation ... I don't think it will produce a natural transparent coating ..

I think it will oxidize and turn your hands black every time you handle it.

Clear spray-on plasti-kote might work ?

I wonder if Car wax would seal it and prevent the black aluminum oxidation ?

Not yet.

[compasillo]

I think aluminum is one of the most resistant metals and their oxide is very stable and hard.
Theoretically, once formed a thin outer layer further oxidation stops. Perhaps a hint
can be gray but I do not think you'll get hands stained black.
In any case, this is only an experiment I carried out several flashlights and have to
wait a while to see the result in each.
Now thinking about a homemade electro anodizing :thinking:

I'll post my impressions once I got some results.

Here are some of my inexpensive little "guinea pigs"...
I have to say my lack of photographer skills don't make justice to
the real appearance of the bare aluminium.

 

[TooManyGizmos]

Well ... the reason I say that ...

I have an all aluminum Little Giant Ladder ......

Every time I use it , I have black on my hands and clothes.

That was my reason.

Good reason indeed...

Though we are going a bit off topic I only can say I appreciate your advise and
try to give a little time to see what happens to the flashlights I experimented with.

Something used on the surface of those ladders?
Thin layer of oil preventing oxidizing but when rubbed with bare hand gives some color to skin? :thinking:

 

[TooManyGizmos]

Oil is not something I want on a metal ladder for safety reasons.

But one day I may try paste car wax on it to see if it helps.

Bare al-u-minium lights do look nice !

I have another question which has better light transmission ar glass or sapphire?

The sapphire is supposed to have better light transmission.

(Edit added: Correction - it's not: read on...)

 

[juplin]

The sapphire is supposed to have better light transmission.

The transmittance of sapphire in 400 ~ 700 nm wavelength of visible light is less than/around 85% by referring to the following graph.

This graph is taken from:
http://www.schott.com/advanced_optics/english/download/schott_sapphire_dec_2009_en.pdf

In contrast, the transmittance of optical glass is above 90%.

Some useful information can also be found in CPF:
http://www.candlepowerforums.com/vb/showpost.php?p=302110&postcount=4

As far as I can see from data I've found, the light transmittance of sapphire should be very close to a high quality mineral glass at around 95%.

 

[jumpin jack flash]

Being very close to pulling the trigger on this light, I have gone through most of the LF2XT threads but still am a little confused about the operation of the light in CUI. Can I go straight to the minimum output (2Clicks) without having the initial user-defined level (1Click) coming on first? From what I've gathered, the initial start up happens instantly, so it doesn't look like I could do 2 quick clicks to go straight to low-low.

Could one of you owners clarify this for me?
