I have the greatest admiration for the Brinkmann Two-Pack at Home Depot for $10. They are headlamps with two white LEDs and one red one. They come with batteries (3 AAA). I use one as a reading light in bed. The red LED lasts for a very long time (many reading sessions). Of course, I have to use the white when I read my red-letter edition Bible.
