This is a great little item! It’s a portable light bulb that you can use when the power goes off, or as a nightlight, a camping light, in your backpack in case you get caught out in the dark, or as an emergency light. You can even use it in place of a flashlight at night. It has a hanging hook too, so you can hang it indoors or outdoors. It has 3 different lighting modes: Low, High, and Strobe. It is an LED light. You can use the strobe to send an SOS message. It’s lightweight so you can easily hang it in a tent without weighing down the tent. You could also hand it on a tree, a rope, or on your backpack. There is a little black button that you push to turn it on/off/low/high/strobe.
It takes 3 AAA batteries, which are not included.
