Sensibly designed USB rechargeable PIR cupboard/hallway light.

This is a nice sensibly designed PIR activated LED light with an internal lithium cell and micro USB charging port. With a quiescent current of about 50uA it should run for a very long time on the internal lithium cell, which can easily be upgraded with a bigger protected cell.
The packaging actually has a technical spec that compares favourably with the tests done on the unit. The unit has a keyhole mounting for hooking on a screw or nail, and a magnetic strip option with matching steel plate for attaching with double sided tape to a suitable surface.

Here's a typical eBay search link with lowest prices shown first. A typical price for this unit is $7 with a choice of cold white or warm white (described in some listings as yellow).
