Just completed AA part of it , will update with 14500 performance shortly ...

Performance on AA's


Eveready Rechargeable 1.4v / 130 Lumen

MP rechargeable 1.35v / 125Lumen

INCA rechargeable 1.35v / 125Lumen

Sony rechargeable 1.39v / 127Lumen

Duracell Alkaline 120Lumen

Varta High Energy 110Lumen

Coles Alkaline 120Lumen

Mine with a 14500 destroyed (still waiting the DX replacement, I dont know why has not arrived yet, hope DX does not fuck me)

Also, viewing your photos, on mine, the driver is different, the down part is different.

Also the difference in lumens between HI and MED on mine wasnt distinguisable....... On MED mine draw 1.0A about 90-100 lumens.

Also mine doesnt had the plastic protector on the clip...........

I got this one ......

Yes, mine was from DX, apparently the same, but mine was without the plastic protector in the clip, and the driver board looks different.....

Probably different batches (or suppliers/manufacturers)

Thanks Matt for the nice review.

The LT version looks considerably nicer than the DX version. Does the mode memory work without too much delay? How's the runtime on low?

Thanks!

On AA

High = 130L - 1.8A

Medium = 55L - 0.78A

Low = 19L - 0.19A

On 14500

High = 0.97A - starts 230Lumen , sags to 210L after 30 seconds

Medium = 0.42A - 105Lumen

Low = 0.1A - 24Lumen

Mode memory is fast .... Very fast ...

Hmm, I saw those current draw numbers, by which I would calculate about 10 hours of runtime on a 2000mah Eneloop. Not too good. They seem to have upped the low mode quite a bit. My Trustfire from DX seems to be about 7 lumens on low, and the runtime is near 24 hours with a good battery.

OK taking into account this:

- The current draws (very different than mine from DX)

- The plastic protector in the clip (dx ones not have)

- The very accurate memory mode (dx ones needs several minutes to act)

- The photo of the driver (different than mine from DX)

- Hasnt failed with 14500

I can say 2 possibilities:

1) Different supplier/manufacturer than the DX ones

2) Same manufacturer as the DX ones but driver changed.

My F20 replacement should have arrived last monday but it doesnt. Tuesday was holidays in Spain, today wednesday not arrived also....

When my replacement arrive I will check if the driver is like in yours........... (if it really arrives, hope DX does not screw me this time)

Wow, didn't found F20 @ LT Only K-106 for $13,59. Will have to search better next time

Man, for less than 12 it's a good torch. And like fran, I really like the driver, hate those awful soldering. Clean driver, like on mine Kingpower. Only one question: what about regulation? On 14500 on high it drops from 230 to 210 in 30 seconds. Could you make the same test but waiting a little bit longer? Thanks

, the sag is heat related , the warmer it gets , the more output is lost , though the regulation is not bad ..

I got 200L with the battery @ 3.8v , so thats rather good . The only thing is going to be the heat , after 30 seconds the head was getting rather warm , after 1 minute I would say its going to be a bit hot .

I will see later when I have time ...

Ahms, didn't know that. Thanks for the info And the led? Really Q5? Have you checked it?

P.D.: hey, fran, are you from Spain?

I think he is and is coming from HERE. Hmm, sometimes I wish I had taken Spanish lessons instead of computer science back in school.

Haha, it's true. And Xrayboy too

Vectrex, better late than never (if you have free time)

It would seem protected 14500's do up to 230L unprotected ones much higher , lets call it 250 + ... Yeah , I think Q5

Hi SashiX, yes I am from Spain

It's the Spanish Armada ... we are surrounded.

@old4570

I have been watching your photos of the F20. The body of yours looks like to be more silver than gold.... I explain, the color of mine is brownish-gold

The akoray k-103, and the uniquefire AA-A1 are silver.

Yours?

More , of a bronze type tinge ... when compared to a Akoray or Ultrafire A20

I no longer have the Uniquefire as it was gifted ...

OK, so not silver, more bronze, brown, gold....... OK like mine

Still my replacement not arrived XP
