The Wisdom 3A is a great two mode lamp for work or recreation! Unlike most lamps on the market, these lights were designed for underground mine use so they are rugged and will hold up for years in tough conditions. The lamp is equipped with a battery indicator system so you can check state of charge at any time. It is light very lightweight (less than .5 lbs.). It's also waterproof to 20+ meters. The lamp is fully rechargeable using the supplied USB cord, or by using the optional NWB-30 charger. The lamp also includes an adjustable steel/nickel bracket.
These lamps have two modes of operations:
High / 12,000 lux / 265 lumen / 13 hours of operation
Low / 1,800 lux / 50 lumen / 60 hours of operation
(This Lamp is NOT MSHA Certified, if you are looking for the MSHA Approved mine light please check out the Wisdom WiseLight 2)
