Well I have been waiting for a "Perfect" flashlight for quite a long time. In my mind a perfect light has to have these characteristics, first of all is perfect making, second is as bright as possible, and then, must a capacity of powerful battery types like 17670 or 18650, and at last, has useful functions. Since I got my first INOVA XO nearly 4 years ago, I was satisfied by it's perfect making, but when time passed by Luxeon Star 1W was going of date, and the size of XO was another disadvantage. Then I turned to AA lights for smaller size and better storing, however AA battery was always not powerful enough to make newer LED to work fully, although there were 14500 Li-ion batteries, they were too easy to over-used. I bought Fenix L1P and JETBeam JET-I MK2 and C-LE one after another, all of them AA sized. Yep I can't denine the joy they brought, when I first put a 14500 Li-ion into JETBeam MK2 to see a 100Lumens' lightness or then into C-LE for even more than 150, but still the perfect light didn't appear, until today.
OK I've been saying so much useless words please forgive me
but I'm too happy to get this one: JETBeam JET-III Pro 3.7V Special Edition.
Less words, more pictures. This would always be good.:huh:
In pictures you'll see this light have changed the normal triangle-shaped screw thread into squard shape. I don't know does this shape have some advantages or not, but at least the feeling in twisting is good. On the surface of all screw threads, the manufacturer applies passivation tech so it shows a copper-like yellow. The coat of this light is also TYPE-III, feeling like ceramic when touching. Very well.
The power of this light comes from a 18650 or 17670 Li-ion battery which can make it burst out a 225 Lumens(MAX) beacon for 1.5 hours. In the lowest mode(2 lumens) light can stand for as long as 150 hours. The LED of it is Q5 bin.
Spec is not important when JETBeam always did a good making. The most impressive innovation is the function it provides. Since different light modes were provided by lights, all lights do have several fixed modes, for example JETBeam MK2 will work under MID-LOW-MAX-Strobe in cycle, and C-LE would be MID-LOW-MAX-Strobe-SOS. As time goes functions of lights are also becoming more and more until changing mode becomes a inconvenience thing. Fenix first made something new as switching general mode set by head and cycling each mode in the very set by clicking the tail. But JETBeam's new system, named I.B.S. is of course better.
In I.B.S. there are three "slots" named A B and C, each can contain a different setting. You can apply whether a output level or a special function into a slot, by switching into one mode and clicking tail switchers three times quickly. The light will enter setting menu and cycling from MIN(2 Lumens) to MAX(225 Lumens) smoothly. Turning off the light when it reaches the demand lightness level over 2 seconds will make the light remember the setting, or the light will enter special function setting menu. As the same, the light will show all of its special functions in turn and to select one, turn off it for longer than 2 seconds.

The next one is beam shot.
Comparing Cree Q5 with Luxeon 1W is not fair I think, also AA with Li-ion. So only MK2, C-LE and JET3 will take place. All lights use Li-ion battery, for CLE and MK2 is 14500(at 4.19V) and for JET3 is a 17670(only 3.71V).
First, 1/125s shutter.
Well MK2 is obviously not bright enough...and 1/125s seems too long for CLE and JET3.
Then 1/400s.
1/400s seems good. C-LE's highlight is proper-exposed, but JET3's is still over-exposed. OK let's try 1/1000s sutter.
This time JET3's highlight is proper-exposed except the very center, while C-LE's become so dim.
At last here is a picture of JET3's beam at 1/2000s shutter.
Conclution:
It throws well, as the beam shot shows.
The beam is not so smooth because of its reflector. Textured reflector can provide a better beam but shorter throwing, so it is a tough decision.
But after all, I like it very very much. It is the perfect one I've ever got and will be my last light until next burst of LED's efficiency.

One thing forgot:JET3Pro is current adjusting, so I can't see any flicker even in the lowest mode.
