I really love my Nitecore DI. For someone with eye problems I'd think that a multi-level light would be useful.
For navigating a dark house, for example; heck my eyes are ok but after stepping on our dog a couple of times (black dog on a black throwrug), that's when I learned the usefulness of always having a light at hand. But I don't want a re-enactment of "close encounters of the third kind", just enough light to comfortably navigate without waking up the house or searing my eyes. Or maybe I need to read something in low-light situation like a restaurant but I'd rather not pull out "super torch"!
But, when I need to track the dog outdoors or work on the car, I have enough light for that job too.
And, if he decides that an "EDC" light is a great thing, the ability to use the proper amount of light for the task at hand adds a lot of utility. 200 lumens for 1 hour is great, but so is a light that can provide several nights of continual illumination in unfamiliar surroundings, on a single battery -- great for travel! And, it's a AA battery, which I think is important for someone who isn't a flashlight hobbyist. with CR123 batteries you either have to special order, or pay through the nose at retail for "camera batteries". The Nitecore does great with readily-available Lithium AA cells, or rechargeable AA. Not as great with alkalines when used on high power, but will do in a pinch.
Surefire is definitely going to give you maximum "packaging bling", but I found the Nitecore packaging quite adequate, with maybe just a little bit of funk to give you the feeling that you're on the cutting edge.
Surefire is top-notch, but maybe just a little too common for the "man who has everything" ?
". Oh good compromise is wolf-eyes lights "I don't know if they all do:thinking:" but they have sick presentation boxes, with just there name on top and logo. Their like all black with a sort of felt inside "defiantly makes for a good presentation:twothumbs" it's real slick
