Powerfully flashlight. Small flashlight. Very cool auxillary lights when off with many, many, color options and 3 main and different choices for how they function. These auxiliarys seem to have no battery drain. (Extremely low).Two weeks and it still flashes 4.1v, amazing. Just a great edc all around. I'm very happy with it.

First: There is no way this light puts out 3600 lumens. I collect flashlights and I decided to put it to the test against a Nitecore EA411, Nitcore E4K , Nitecore EC30, Fitorch P25, Roryvon A23, Roryvon A2.
The only one I can say it beat outright was the Roryvon A2 but remember that light is rated at 650 and is about half the size of a crayon. The Roryvon A23 is about as close as you can get in light output, but it's rated at 1000L and is about half the size overall, but the Jetbeam's light isn't as crisp.
That also is another point, the light itself. There is no clarity to it, it just kind of fuzzy and distorted with a haze.

Second: The switch feels really weak. Not so much the actual button but the rubber cover feels like if you push down with your thumb nail it will cut through it. I can actually feel the prong for the switch when I push down, It is that cheap.

Third: Now I've been critical on a lot of the different light's user interfaces, but this one takes the cake. I guess if you just want to set the level and use on and off you may be OK. However, if you want to use any of the modes that they say are available you will drive yourself crazy trying to figure them out. Hell they even got modes on this that flash red, blue, green and they call it party mode (good luck figuring out how to get there) They even give you a failsafe to get out of all of the modes if you get stuck somewhere? What? If I get stuck somewhere, I need to reset the light, too much gimmick.

So, we have a light that puts out an under rated distorted beam, with a flimsy switch and a almost comical use pattern. My first Jetbeam and probably my last.
