I have now bought three AA's. Given away two as gifts and gave myself the last one. Unfortunately I felt I had to give back my 4+ rev.2 (after the switch fix)...it just was not working for me.
However there a features of the AA that are classic and maybe THE light to get from Arc if:
1.) A brighter, whiter LED, like the Luxeon Star.
2.) As stated on another thread, a 'Hi'-'Low' setting.
(possibly setable by the user, but not that important.)
3.) The ultra low brightness option that is available on the 4+ by triple clicking, (liked the feature-hated the clicking) would be great.
4.)Lose the tactical, blinking, S.O.S., features. They are needlessly confusing.
This thing is a tank, uses readily available AA batteries and is small and stands on its tail. Pump up the featues, sell forunder $100. Preferably under $75. And you've got a 'war winner'.
