Great for reading or seeing in hard-to-see spots, the Energizer Book Light easily attaches to where you need warm white light. It’s the last clip-on light you’ll ever need because it makes a great reading light. The warm white LED light provides a more natural reading experience with the excellent contrast you need to read. The scientifically designed beam is engineered to provide wide illumination and reaches up to 4 meters—far enough to double as a personal flashlight. A flexible neck allows you to precisely direct the light for reading—or use it as a compact LED flashlight for household and automotive tasks. This little reading flashlight is impact-resistant up to 1 meter for durable use. Includes two CR2032 lithium batteries to provide a run time of 25 hours for long-lasting light. When not in use, this slim LED book light collapses and locks for easy storage. Get the performance and power you count on from Energizer with this battery powered book light.
