Underwater Lights

Custom Master's underwater lights are canister-type primary lighting systems for technical diving. A canister light consists of a separate power unit worn on the gear and a head on a cable — this reduces hand fatigue and lets you aim the beam independently of body position. Battery capacity is 10 to 30 Ah depending on configuration, with 6 to 20+ hours of runtime. Light heads are available with different beam angles: from a narrow 10° for long-range lighting to 120° for general use. We also help select and configure backup light systems for a complete technical setup.
