The main body is small and, above all, light, but it's quite bright. It doesn't take up much space in a bag, which is very convenient. The lantern part is also bright, with both a dim and a bright setting; even on the bright setting, it lasted for 4 hours. Having two allows you to use both the light and the lantern, making it suitable for outdoor activities and working in dark places. It doesn't require batteries and charges in about an hour, which is very convenient. Currently, it's sold out at Daiso stores, and many stores are waiting for a restock, so if you want one quickly, please consider purchasing. One unit costs 500 yen, and you can choose your preferred color. Brightness (lumens): 100-299lm Features: Rechargeable Type: LED light
