This innovative clip-on solar light is ideal for use in camping, backpacking and hiking - or just use it around the home/garden for supplemental solar lighting where needed. With an internal solar panel and rechargeable battery, the M-1 clip light attaches anywhere and provides a bright light source when needed. A soft-touch switch turns on the 2 main lights in either low or high output or turns on the single small edge light, providing you with 3 lighting options depending on your needs. Expect about 4 hours of operation in high power mode or up to 8 hours in low power after charging in full sunlight for up to 8 hours. You can also charge the M-1 clip light using any USB charger (the port is a micro-USB - no charging cable is included). We use ours on a stroller at dusk and while walking the dogs in the evening. There are hundreds of uses for this versatile and clever device. Packaged as a set of two (2) clip lights (see other listings for a single lamp).
