It's much cheaper to feed than anything that takes coin cells! My only complaint is that the beam has a very sharp edge, no side spill at all, so it's not good for walking around. I should just open up the end of the light stalk... Their night-vision claim is backwards. The pigment rhodopsin, which builds up in the retina's rod cells, is most sensitive to green light like Ben says. Using a green light source will give you a lot of perception for very few watts of power, but doing so prevents the buildup of rhodopsin that leads to the highly sensitive scotopic vision we known as "night vision". To preserve night vision, all the light sources near you need to be red, 640nm wavelength or longer, because rhodopsin does not react to deep red light. This allows you to view instruments, read, or otherwise work up close on reasonably illuminated objects using your cones' iodopsin pigment, which is responsible for photopic "day" vision. When you need to see dimly lit objects, your rods are ready with their buildup of rhodopsin, which can be so great after prolonged adaptation that you may be able to perceive single photons. Using a green light or a green laser will appear remarkably bright, but it'll spoil your night vision. (So will blue, white, or anything other than pure deep red.) http://hyperphysics.phy-astr.gsu.edu/hbase/vision/visioncon.html I have the AAA-powered version, which I believe I found at Circuit City.

So maybe there is some truth to their claim... All said, it is still pretty silly looking-I think head mounted lights are the best solution for this purpose.
