I Spent some time looking for the ultimate all round flash light and came up with this:
Hi CRI Steve Koo 40DD Flash Light half the size of your finger: Its super small, Super Powerful, Rechargeable from your computer, It can go super bright or super low. $59! Think its my favourite item of the year.
