i have both the attitude and impact 2.
they are both nice. the impact 2 i am just a bit diappointed with, because it uses a projector lens to throw the light. this results in a bright and narrow spot which i find to be less useful than a broader flood. i prefer a beam with as few artifacts as possible.
the attitude is one of my favorite lights. it is light, small, reasonably bright and inexpensive. it fits nicely in a light jacket pocket, or even in a deep front pants pocket.
it is a tough little light.
it is also waterproof. the beam is a broad flood with a mild central hotspot. the beam is pretty smooth. it also has a very long runtime.
it doesnt seem very bright at first, but once your eyes are dark adapted, it is very bright (too bright to read with!). try it around a dark house/shed/garage--it lights up a large area nicely.
mine is much more blue than say a white luxeon, but it sill is very nice.
as an aside, i have ordered an inretech, and will give my impressions soon. it should be much brighter/whiter, but will also be heavier, longer and more expensive. i intend to try a mcflood in it--should make for a great beam! (the nx05 should provide longer throw, if that is what you are after)
also, my inretech/minimag combo will use lithiums, which should not only be very bright, but will have good cold resistance, be lighter, and have a VERY long runtime. not bad for about $30 total.
look at Roy's runtime graphs in the reviews section (he didnt test the inretech with lithiums, but the curve should be similar to the reactor with lithiums, which is amazingly long for an unregulated light)
my EDC light is the infinity ultra with li battery. bright little bugger, small, light, long runtime, tough, can use li for cold resistance.
next comes the attitude (which MAY be replaced by the inretech mod) which resides in my coat pocket or glovebox.
and finally is the tec-40 with kpr113 bulb. not quite as bright as the stock bulb, but it has a MUCH smoother beam. should have a nice long runtime, and be pretty reliable. the bulbs are inexpensive too. a word about the beam: the tec 40 has the power of a 2 or 3d mag, in a much smaller package...and the beam is FAR nicer...plus, i can use lithiums! a remarkably nice yet inexpensive light!
i will never use a stock mag again.
have fun with your search!
