The Nova 250 is a versatile dive light that can be stored in the smallest BCD pocket. It offers three modes: 100% power, 50% power and Flash, plus is equipped with an over-pressure valve to release battery off-gassing, making it the safest small light on the market. Delivering 250 lumens of illumination, the Nova 250 is powered by a CR123 battery (rechargeable or disposable). The CR123 disposable battery features a shelf life of up to 10 years so you don’t have to worry about it if it stays in your BCD pocket over the winter.
