The TrekUltra solar LED light can be used for late-night smoker/grill sessions, camping, emergencies, and more. With a powerful 90 lumens of power and a weatherproof exterior, this light is safe to use inside the house and powerful enough for the darkest woods. It can either be charged by incandescent light or by direct sunlight, meaning it can be used outside even in the toughest conditions—including 0-120 degrees F. This light offers three settings (low, high and flashing), and features two strong magnets so it can be attached to any metal surface.
