I bought a Lambda Illuminator
I bought a Lambda Ill Pill
I liked them both
I finally broke down and bought an ARC LS.
It lives on my keychain along with my Arc LE (can't have too much backup) and it is becoming my most-used light. I have an E2e in my other pocket, but the LS is cheaper to run and bright enough for most things. The Arc LE isn't bright enough for some things--like looking under desks, etc.
Cheers,
Richard
