The Everglow Light Tube is a slim, air-inflatable lantern that is powered by a portable battery and glows with LEDs. If you put it in a special bag, it is about the size of a 350ml can, so it is convenient to carry it anywhere.
This product was developed by Klymit, a company located in Utah, USA. This product is waterproof in the form of a tube as well as lighting, so it is convenient to use outdoors. Not only is it small, but it is also light in weight because it expands with air. If you use the supplied magnet, you can attach it to a car or tent and use it comfortably.
Since the power source is USB, it can be connected to a PC and used for remote work. The basic model has a brightness of 160 lumens, expands to 46 x 8 cm, and costs $19.95. For 220 lumens, the 66 x 8 cm is $29.95, and the 86 x 12 cm extra-large model for 270 lumens is $39.95. Related information can be found here.
