Review: UniqueFire A20 , formerly the Ultrafire A20

For review I have the Uniquefire A20 5 mode  1x16340  from KD 


Now this was formerly the Ultrafire A20 , and is listed by KD as the Ultrafire A20 , and for all intensive purposes is a Ultrafire A20 except it has a new name printed on the body . Everything appears to be the same as before , but this is not really the case . The light is well made , and no complaints there , what took me by surprise was the output and current draw when I got around to testing hard figures.


  So lets get to the performance "  

 


On high it produces some 120L @ 0.37 to 0.4 Amp 

On medium it produced some 60L @ 0.18 to 0.2 Amp

On low it produced some 12L @ 0.03 to 0.04 Amp 


Now while 120L is not a very high output , one must look at the current draw of 400mAh , which is actually excellent fuel economy . My previous A20 did some 290L @ 1.6A , and that was certainly impressive , but offered very poor run time as a result . A 16340 is not going to last very long @ 1.6A , in fact its very bad , for anything but short trips to the back yard . And while its nice to have a small pocket rocket [ high output EDC ] , they dont offer much run time on high . So while this particular sample does not impress with the output , I actually am impressed with it , for offering a very sane amount of light at a very usable current level . Now I did order another to see if this was simply an anomaly , or if there all going to be like this now ? 


  Its only fair to say I bought this light to be a mod host , as the A20 makes for a very nice SSC P7 or XM-L host for building pocket rockets . I like this one as is , though I no longer am a fan of the XR-E emitter , and I'm very tempted to put in a XM-L emitter  for the beam quality it offers , I will try and wait for the next one to see how that performs . [ One of them will become XM-L ] 



Well Made 

Knurling well machined 

Threads are well cut [ the two halves screw together very smoothly ] 

Nice beam quality 

Wrist strap 

Op reflector

Nice Clicky  [ a little soft for me ] 

Will tail stand well without wrist strap

Glass lens

No mode memory , always starts on high 

Output is much lower than Im used to  

Offers long run time 

5 modes , Hi - Med - Lo - Strobe - SOS [ would be ever so sweet less - Strobe - SOS ] 

Still a great mod host .

I ordered a second one to see if the current draw was on the lower side .
High - 172L- 0.63A , 
Med - 86L - 0.3A , 
Low - 17L - 0.06A  

Looks like the current has been seriously backed off , I will keep this one and mod the first one ...

I have a U2 XM-L and some KD XM-L drivers , so as time permits . 

 Always remember , the easiest thing in the world to do , is to expel hot air from your lungs and through some vocal chords ..
The resulting sound may , or may not be worth listening too ….

I tried to purchase this torch from 3 different vendors (including KD) when it was still branded Ultrafire and no one was able to deliver. I really like the torch alot. I would really like the pocket rocket version though since there is always medium and low for extended runtime.

That's a good looking light, and nice review. Thank you.  For the time being though, I'll keep my xml "pocket-rockets" 18650 based.  Such a huge increase in runtime for a nominal increase in length. The one exception to this is the Nitecore EX10 which I recently upgraded to a NW xpg.  It'll put out just a hair over 300L on an IMR 16340. Having just said that, this A20 would probably benefit from the same treatment.

The idea was to turn it into a XM-L U2 hot rod , but Im thinking I might keep this one as is , so I ordered another ..

I like the A20 platform , but the SSC P7 and XM-L really eat batteries [ eat through them ] especially the XM-L mod which pulls over 2A , so it would be nice to have one that runs over an hour on high , + 120L is plenty , and it does not always need to be about power [ ?  ?  Did I say that ? ]

Ha! Don't feel bad...I've been having those thoughts as well, and have just recently renewed my love for neutral xp-gs... Hopefully it's only a temorary psychosis...

But it is about power...and...economy. That's what low & medium modes are for - economy. Single mode lights force you to compromise on either power or economy. Man invented multi-mode so he can have his cake and eat it too. Go ahead and mount that XM-L and drop that badboy driver in there too, while it's open. Wink

Yes ,for some hot models ,the factory may print different logos ,such as Ultrafire C8 and Fandyfire C8 .The difference is the emitter and brand . But for each brand ,they also has their unique models ,such as ultrafire 501b 502b ,and fandyfire HD2010 , G36 ,“5 CREE”:http://www.lightscastle.com/product/fandyfire-5-x-cree-xm-l-t6-4000lm-5-... .
For many people ,they may like one or two brands ,and they’d like to collect a series of the brand products ,but for some others ,what they care is the model ,appearance but not the brand .
