This little beauty packs 900 lumens of grunt from the 3 "C" sized batteries. The barrel is made from high strength Anodized Aluminium and is only 210mm in length, double o-ring sealed with an easy twist activation. Burn time 8 hours. Small enough to fit in the BCD pocket or the cray bag, tough enough to cope with kiwi diving and waterproof rated down to 100m.
