Pros:- Very bright. Just about as bright, if not more than my 100-Lumen Surefire. So I would estimate REAL lumen output is around 100-110. - Tightly focused beam. Dot is very tightly packed and has excellent throw. Dot is also very clean looking, no abnormalities in the beam quality. - Great looking host. Probably one of the best I've gotten from DTW. Very clean, fluid and sharp looking. Not awkward in the least. - Great knurling. - Easy disassembly for replacing/exchanging internals.
Cons:- Paint chips off very easily when dropped from low heights on hard surfaces.- Sometimes (very VERY rarely) has trouble making connection, have to shake a bit every now and then to make it work.
Other Thoughts:Reverse clicky. Heats up quickly (though not a bad thing, just shows it is powerful).
Bottomline:Great light with a lot of power. Use rechargeable RCR123's for about a hours worth of light, maybe more. Great host for other emitters if you can find any that are brighter.

Disappointing Flashlight from Ultrafire

Pros:Bezel looks good. Nice to hold in the hand. Good quality lanyard attached. Can stand on it's face.
Cons:Not bright at all. Very disappointing build quality and very poorly finished. Some 'scratches' in case and anodizing very thin. Quite sharp around the edge of te bezel. Too much play ion the clicky before it connects.
Other Thoughts:No holster provided which, at this price is surprising. There are too many niggling quality issues to have just have received a sub-standard model. I would be interested to see other ultrafire products.
Bottomline:This is not a bad flashlight but it's not in the same league as, for example, a Romisen RC0F4. Since it's also more expensive than the Romisen there's no contest = I can't recommended this flashlight. Hopefully this is not representative of other products from this manufacturer...

Bright, Strong, Doesn't Fit 18650

Pros:I received it, and the first though was: "This is smaller than I thought." It was decently built. It looks and feels real solid. The light is bright enough (Hint: Don't stare in directly...can't see now...) only i wasn't able to test it fully (read cons.)
Cons:It doesn't fit ANY of my 18650 batteries. I was able to test it by just tearing of the plastic of one of my batteries, and connecting it to the bulb and the spring. Which worked fairly well, meaning the spring makes good contact with the battery.
Other Thoughts:Because it doesn't fit an 18650 as advertised, I've given the build quality a 3 star. If they just made the tube 1 or 2 mm larger, it would surely fit without a problem. I've contacted dealtoworlde to ask for another model which does fit the 18650, and send this one back. Waiting for a response.
Bottomline:Don't purchase this if you plan to use it with an 18650.

Happy with purchase

Pros:10 days to mail item to Canada. Awesome little light, I would totally recommend this light for anyone. Very rugged, strong black anodized finish and professional glass lens not plastic.
Cons:This is a very rugged light, my only concern would be the glass lens, I don't know how strong it is.
Other Thoughts:I am using 2 ULCR123 rechargeable LI-ION batteries, this light is bright. When you pass it near closed eyes it is almost blinding, even at a distance. I used a light meter at work, results are in foot-candle:From 12" away - 360 foot-candleFrom 6" away - 750 foot-candleFrom 1" away - 1740 foot-candle
Bottomline:Buy this light!
