This is the lamp you’ve been waiting for!? It is light weight (less than .5lb), IP68 rated waterproof to 20+ meters and functions as a power bank to recharge your cell phone or other USB device such as tablets and GPS!? Lamp is equipped with a battery indicator system so you can check state of charge at any time and is rechargeable using supplied USB cord or with the NWB-30 Charger (sold separately).? Unlike most lamps on the market, these lights were designed for underground mine use so they are SERIOUSLY RUGGED and will last for years!

A long run time, rugged build and ability to charge phones and small electronics makes this the perfect light for mining, outdoor sports, emergency preparedness, bugout bags and more!
