My cheap rechargable flashlight

Got this a couple months back, Figured I would do a mini review.


It is a surefire knock off , called ultrafire XML-T6
Model of LED: CREE XM-L T6 LED
Internal wiring applies the high efficient booster circuit, working voltage is wide and can utilize the batteries in the largest extent
Waterproofing design
Aluminum alloy casing
Aluminum alloy reflector
switches-tail cap on and off (Press heavily to turn on/off the flashlight)
3 switch Mode: high/strobe/sos (Light press to turn the mode to another)
Power by : 1 x 18650 3.7v

It was super cheap , but I am surprised how well it works!!

here is the light , battery and charger.

Full charge takes about 4 hours, normal intermittent use it stays charged well over 2 weeks before any noticeable change in brightness

I shot this in the darkest room I have I will shoot another tonight outside.

Pic is black....batteries ran out?

@ hunter LOL its a video, you have to click on it to see it . I don't know why it loaded that way!

ok uploaded to youtube its still processing!!!!

http://youtu.be/yRPdkEiD2Iw

Yeah, well I'll take your word for it.......LOL
I'm out here in the boonies, with a modem, vids load so slow I can't watch them unless I have a 1/2 hour to burn.
Thanks for the effort.

Ill post some pictures tonight when its dark out . I'll keep ya in the loop.

Thanks .....appreciate it......

Thanks for the review. The best rechargeable batteries I've found are Radio Shack but they are pretty darn expensive. I'd like to know which rechargeable AA and AAA folks have had good luck with. It looks like that one is a proprietary battery?

it is , its 3.7 v made for the ultrafire lights.

Oddball voltage. Hmm. Thanks!!

Speaking of rechargeable batteries, did you know that there are 2 AAA and sometimes AAAA rechargeable batteries in those dollartree solar lights !!!!

Nice thing about it is there cheap, I can get 2 of the batteries for 9.99 shipped.

I've tried the Duracell and Coppertop and they just don't seem to last very long. The Radio Shack do a nice job but they must be gold plated.

i have had good luck with the fuji brand and also the kodak brand but there a little pricey too!!!

welderguy, I've got two of those ultrafire that use the 18650 batteries but mine will also use 2x 16340's (lithium ion verson of a cr123)
I don't know if your's can use them but it doubles the output. Ultrafire make many different types of these flashlights.
My favorite light of all time is my Balder SE1
With a small 14500 Lith Ion, its seriously brighter than one of my car head lights.

When I got this one I thought it was the one that would use the cr123 but it isn't . I saw several that I like by ultra fire, I may add them to my collection some day soon.

That's pretty close to what you would expect from a triple-cell NiCad.

It's also just the right voltage to keep you in a safe/reliable upper and lower voltage range for 3.3v cmos logic, which has become very widespread in portable electronic devices.

That is good to know.. Now can you translate that please!!! LOL

CMOS is how you tell which side of the circuit board faces north.

I just got some of the ultafire lights and have been very pleased with them. Small enough to fit in the palm of my hand yet throw out incredible light with a AA sized battery.

I have been doing research on this very topic. I haven't done a lot of trial an error though, mostly just reading reviews on amazon. To start, the best AA and AAA that have a voltage around 1.2 are the Nickel Metal Hydride. There are also two main types of NiMH batteries on the market, one has a current density around 1500 mAh, and the other is above 2000 mAh for the AA size. From the reviews on amazon, the eneloop brand seems to be a huge favorite.
The type of charger for the NiMH also seems to be important. They need to be charged correctly.

As for the 3.7 V battery from the OP, that is common for Lithium Ion batteries. You can't get a rechargeable lithium battery less than 3V.
