MdTEK MDV8K Light 8000 lumen

The MDTEK MDV8K is a combination-head underwater light for video, photography, inspection and visual support in technical diving. It integrates a wide light source to illuminate the scene and an auxiliary spot beam for orientation, signalling and selective lighting.

This commercial configuration is supplied with a backmount cable and a 77.7 Wh canister battery. The set is designed to be integrated into a technical diving configuration where the canister, cable and light head are secured and do not interfere with valves, hoses, inflators or emergency procedures.

Important: this is a video and visual support light. It should not be considered on its own as a primary safety light for technical diving; keep the primary and backup lights required by your dive plan and training.

Use and maintenance

• Inspect the seals, closure, glass, cable, connectors, contacts and mount before every dive.
• Use the supplied charger, charge in a dry, ventilated place and never leave the battery charging unattended.
• Do not switch the light on at high power out of the water, except for a brief, supervised test: the light head needs water cooling.
• After diving, rinse with fresh water, dry thoroughly, and do not open or disconnect the unit if there is moisture on the contacts or canister.
• If there is flooding, smoke, abnormal heat, swelling, an unusual smell, flickering or erratic behaviour, take the equipment out of service and contact technical support.
