I think the Arc AAA, white led or the LE is a premier EDC...I use mine at least several times per day. If you are not used to led's, remember, they do not project like an incandescent bulb, but are truly amazing for night adapted eyes. The LE puts out a mini blast of useable light in a TINY package.
Depending on what you can carry, the Minimag with Newbeam modification is a stellar product. 8 hours of regulated output in a very durable/sturdy package. It is fully regulated, so output is totally equal, then a red led comes on to tell you you need to change the batteries. It has 3 led's that give good light for household and out door use. Check out the led museum site and look around other's sites, like Quickbeam's...everyone loves the opalec.
The E2 is a great light for intense light...75 min runtime, not regulated. I have one, but don't use it much now.
THe luxeon Star mods that Dat2zip, Lambda and Elektrolumens are doing are just g.d amazing...I can't help myself from buying them.
