I'm surprised at the criticisms of the mule effect. I own a Preon 0 and the titanium version, i.e. the AAA Atom, which have the same beam profile as the new 123 Atom, with a lo of about .5 lumens and a high of 35-40 lumens.
I think both levels are *incredibly* useful!
Of course they are not for outdoor or trail use. But for indoors, they are great.
With dark-adapted eyes, the .5 lumen mule is perfect for walking around the house. You can see everything, and because the light is so diffuse, you never lose your dark-adaption.
The virtue of this kind of light-dispersion is that 1) everything within your peripheral vision is illuminated, but 2) the light doesn't seem to be coming from anywhere in particular. You don't see any *light*, you just see all of the *objects*, evenly illuminated.
I think that the brighter, 123 version, will be great for a range of indoor uses--anybody who is working on wiring a junction-box, or putting insulation into an attic, or upside down in a crawl-space, will find it a perfect headlamp.
Yeah, it's a different experience from a thrower. Certainly not for every environment or every function. Maybe not for every user. But I'd strongly recommend that every user try it some time--I think you really get to experience a different way of seeing.
