I'm researching to find a small solid state device that converts 110V 60Hz
AC to 5V DC. Ideally, this device would screw into a standard light bulb
The application would be for pretty low current draw (prolly not exceeding
I was told at one point there existed such a device, but haven't had any
luck tracking one down.
Does such a thing exist?

Why look for such a specialized device??
Get a standard lamp to socket adapter. ( ~$.30)..
Then plug in your favorite switching wall wart AC to DC adapter.
The AC adapter which came with my D-link wireless access point
weighs in around 3 oz and output 5vdc@2a.
