Im looking at the Trustfire F20 today , its AA - 14500 capable [ my main interest being AA ] , and mine came from Lightake.com , and took a little over 1 week to arrive . The pill was not tightened as it arrived , but thats ok , as I usually remove the pill to cut some slots in it to make tightening and removal much easier . You can see the cuts clearly in the picture bellow .

The 100Lumen claim for output is nice and conservative , I like that [ For AA ] , and I was a little surprised by the performance .

Also surprising was the build quality , square cut threads , a decent clip [ just ] , nice even anodizing , solid clicky ,

very nicely cut knurling , GITD O-rings and tail cap , and nicely spaced out modes with mode memory , and it does tailstand .

If there is anything to complain about , it would have to be the lose pill on arrival [ not an issue for me ] , and what I would like to see is not so deep a recessed clicky , and a stronger clip , as well I would love to see a straight Hi - Med - Lo version , mode memory means you have to go through strobe and SOS to get back to high from Low .


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


Modes


High = 130L - 1.8A

Medium = 55L - 0.78A

Low = 19L - 0.19A


Im sorry there are no beamshots as it was raining rather hard last night , so hopefully I will be able to get some tonight [ I hope ]

I will update this asap , with some 14500 figures , but I just wanted to post this as I was rather impressed with the performance on AA's , and to date I would suggest this might be the best little bargain going in AA capable flashlights ...


14500 Performance


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

Medium = 0.42A - 105Lumen

Low = 0.1A - 24Lumen


On high the light begins to warm up very quickly , and the output begins to drop as soon as you turn it on , so I would suggest that anyone buying this light be happy with the above average performance on AA's . I also would be remiss if I didnt mention that some folk have apparently killed the drivers when using 14500 batteries , though mine seems to run fine on a 14500 , and does not appear to affect AA performance in any shape or form . [ Some lights when run on 14500 , suffer from deteriorating performance on AA's as a result from being run on the 14500 ]

I have one of these - at least I think it is - mine says Trustfire R5-A3

Its the most disappointing torch I have bought. It overheats, the claimed lumen output is "optimistic", battery consumption is more than heavy.

There are much better torches out there for the money (even under the "no name") brands.

Really guys, save your money

Great review - I'd seen Trustfire lights and batteries on Deal Extremes site, but its good to get such a detailed review. My only problem is that now you've pointed out a new website (Lightake), which has some Romisen lights which are either not on DX or have better leds. Temptation is a terrible thing...

BTW - is this item http://www.lightake.com/detail.do/sku.iTP_C9_Cree_7090_XR_E_Q5_3_Mode_190_Lumen_LED_Flashlight_%28Regular_Version%29-%2027668 possibly in the wrong place?
Sorry for late reply , Lightake is very similar to Dealextreme, but there have some gadgets that Dealextreme didn't have .
Yes , there have some product with a nice price.you might can have a try !

Thats cool, differing opinions are allowed. I just wanted to offer a different perspective on th ebrand. Perhaps yours in a newer model and they have ironed out the problems.
