For outdoor work, the UST Gear 14-Day LED Lantern will solve your personal lighting needs. It is powered by 4 AA-size alkaline batteries. You can easily purchase off the shelf of any convenience store, making sure that you can find power anywhere you are.
It offers a maximum brightness of 140 lumens that will last 13 hours – but if you need extended life, it has a low power setting of 16 lumens that will last up to 14 days.
The lantern is designed for rugged use. It has an impact-resistant housing, capable of absorbing falls with no damage up to 3 feet. It also has an IPX4 Environmental Protection rating so you can use it in the rain. The integrated grip is rubberized to keep it secured in your hands and doubles as a loop to hang the light above your head.
