A nice one page story on the military version of the U2 being rolled out this month. Makes me want a U2 badly.

In the back of the same issue, an ad from Surefire with a testimonial from a Marine who took some incoming and the only surviving piece of equipment was his Surefire weaponlight.

How is the military version different?

The military version (named DEF3A) looks like the U2 but it has a larger head with a Luxeon V and generates 120 lumen vs. the U2's Luxeon III's 80 lumen.

The article also mentions that the U2 has a dimmer and the DEF3A does not.

The DEF3A has sixteen colored LEDs for signaling - green for safe, red for under fire, etc. and infrared for use with night-vision equipment.

They also mentioned that the DEF3A beam shines through a aspherical lens that captures and redirects twice as many photons as a flashlight with a parabolic mirror.

There is always a 1 page add in Pop science and Pop mechanics for surefire, even though the add is almost always the same it is the first thing I look for in my magazine. :)
This month there is a new one page add from a company called Lens Light, www.lens-light.com..

Small correction: U2 has a Lux V - not a Lux III.
