I like this light a lot, it has a lot of uses actually. I use it all the time when my wife is sleeping and I need to go into the bedroom. With her illness she needs her uninteruppted rest and the X1 gives no sidespill to disturb her. I used it this weekend when working in an area on a furnace where I tried a normal light and the sidespill kept reflecting off a bright piece of aluminum, and kept bothering my right eye.
I wish it was brighter too sometimes, but it is really brighter than a lot think I believe. I think the no sidespill gives the illusion of less brightness from what we are used to, but things within the spot are illuminated rather well, especially at small to medium room ranges.
This light takes the place of all those hooded penlights, covert photons, etc. very well, it is the covered lantern of this day. And yes, some of the uses can be a bit illegal as if I were a burglar this is what I would use.
Is there any "tutorials" to show how ot open one of thse lights up and replace the led with a stronger, or is it pretty much trial and error? Ruining the light and replacing it in these days of high medical co-pays is not an option...
