Sometimes you just want to curl up with a good book. Late at night. Outdoors. This light allows you to do just that without balancing a flashlight between your knees or bothering your tent mate who may be trying to sleep nearby. The integrated clip is inserted into the spine of your book or magazine to anchor the light. A flexible gooseneck holds the head that contains two bright LEDs. One AAA battery (not included) lasts about 20 hrs. 8.5"×2.5"×3.75". 1.3 oz. 3 lumens. Flashlight Comparison Chart
