Underwater Kinetics Mini-Q40 MK2 Dive Light

The Underwater Kinetics Mini-Q40 MK2 Dive Light is a compact hands-free dive light built for travel, lobster diving, backup lighting, and everyday underwater visibility. Small enough to pack easily but bright enough for real dive use, the Mini-Q40 MK2 produces 250 lumens with a focused beam that cuts through dark ledges, low-light conditions, and murky water.

Powered by four standard AA alkaline batteries, the Mini-Q40 MK2 delivers up to 5 hours of burn time and is depth rated to 328 ft. / 100 m. A rear push-button switch makes operation simple even with gloves, while the included mask strap attachment allows divers to mount the light for hands-free use.
