Underwater Continuous Lights

Select based on intended use: higher lumen output and wide beam angles for video/photography, compact units for recreational diving, and durable housings with high IP/ATM ratings for prolonged submersion; also match battery runtime to typical session length

Aim for 1,000+ lumens for video and 5,000+ lumens for professional photo setups, and choose 5000–6500K (daylight) for color-accurate footage; adjustable intensity and color temperature are useful to match depth and water color

Run times vary by output level and model; expect anywhere from 1–10 hours depending on brightness and battery capacity, with many units offering removable/rechargeable lithium-ion packs or integrated batteries with USB-C charging

Check the IP rating and maximum depth rating (e.g., meters or ATM), materials such as anodized aluminum or marine-grade plastics, and secure seals/O-rings; confirm user-replaceable O-rings and serviceability for long-term reliability

Yes—verify mounting options (tray, arm, clamp), standard thread sizes or ball mounts, and whether the light integrates with your existing camera rig or dive equipment to ensure secure positioning and ease of use

Rinse with fresh water after each saltwater use, dry and inspect O-rings for damage, replace batteries or charge per manufacturer guidance, and store in a cool, dry place to prevent corrosion and seal degradation

Prices generally range from budget options under $100 for basic recreational lights to several hundred dollars for higher-output, feature-rich units; higher-priced lights typically offer greater lumen output, better build materials, longer runtimes, and advanced controls
