I bought this light:

The Mighty Bright Xtra Flex 2.
It is a REALLY bright LED,with two settings. It's so bright that it sometimes bothers my husband if I read in bed while he's sleeping. It has a really nice clip and it's really flexible and adjustable. It runs on AAA batteries.
Like I said, just extremely bright!
