This is a handy little LED light that runs on a single AAA battery. It’s made for marine signaling, but it works great around the camp. It has a broad, diffuse beam that is bright (25 lumens) and lights up a large area.
Totally waterproof. Twist on and twist again for the SOS. Maybe you won’t need the SOS around the campfire, but you never know. Made of sturdy ABS plastic, about 1 x 3 inches long. I’ve found that it works great in the tent as a reading light. Comes with a carabiner that enables hanging from your tent stays.
