We use these in our trailer when camping.  Nice to curl up with a book and read at night, and not worry about draining our batteries in the trailer.  I also use it as a night light in the trailer, if I need to get up in the middle of the night.  I just clip it to the window valance.  Gives off good light for reading.  I like the fact it has 2 settings, so you can click it twice for a dimmer "night light."
