I love this little light!  The clip attaches comfortable to a wooden drawer that's 1" thick.  The light is adequate for reading, and the neck is smoothly flexible.  I also love that it uses LEDs.  Can someone point me in the direction of an adaptor?  I would be interested in one.  I would like to note that this light did come with 4 AAA batteries.  Also, the light has 3 settings:  off, on, and "really on".  There's not that much discernible difference between the two "on" settings.  It's clear that one of the LEDs isn't lit for the dimmer setting, but the reduction in light output is barely noticeable.
