Wow this is bright, and has multiple uses! I started reading at night to help me get sleepy for bed. I couldn't keep using my bedside lamp because it put out to much light and would keep my wife up. The fix was to buy a decent book light and this is more than decent. It is bright, consumes very little power, and has uses outside of reading books. The obvious use is for reading but if you are a handyman type, any time you are working on electrical wiring, it can be clipped to the edge of an outlet box, hole in the drywall, to your shirt, etc. This has come in handy more than once. Highly Recommend!
