The Nova 850 diving light delivers intense illumination, ideal for lighting up the dark spaces and bringing out the vibrant colors on night dives as well as day dives. It is machined from heavy-duty aluminum with a rugged matte black finish so is both lightweight and built to last. It’s also easy to use. A 50% mode allows you to increase burn time if you don’t need the full power. For divers looking to brighten their dives, the Nova 850 is the perfect choice. The Nova 850 is powered by 3 C cell disposable or rechargeable batteries (not included).
