I would think that these dim illuminators would be quite useful in military applications where stealth is part of the requirement. Using something this dim while hiking in the dark with or without NVG could be a good way to keep your forces together. When there is no other source or illumination and you have one of these hanging off the back of you helmet or such then it would be pretty easy for those following you to keep up even if you got a bit out-front. OTOH, that would also make you a decent target for anyone watching so....

Also attaching these to the tie-outs of your tarp / tent or to the tent stakes could prevent a trip / fall accident or a stubbed toe.

Just theorizing here as I haven't yet spent / wasted the money necessary to own one of these.

A couple of useful stats could aid the discussion.

What is the wieght ?

What are the lumens new?

What is the useful life at "full" brightness?

What are the deminisions?

Anyone have any true life experience with using these devices? What did you use them for? What were the results? Have you used anything else for that use? Compare and contrast?
