With a beam distance of up to 400–500 meters (in air), the Helius Sealux throws a focused, balanced beam that cuts through dark water while still providing enough spill for situational awareness. Whether you're checking reef structure, navigating around a wreck, or working in murky conditions, the beam stays clean and usable underwater without excessive backscatter.
The 3000 lumens SFT40 LED combined with 4100K neutral white output helps restore natural underwater colors more effectively than harsh cool-white lights. Fish, coral, ropes, and underwater structures appear clearer and more detailed, especially at depth where colors quickly disappear.
Built from rugged aluminum alloy with IPX8 waterproof protection, the Sealux is made to handle demanding environments including scuba diving, marine inspection, rescue operations, and outdoor exploration. The compact handheld body is easy to carry while remaining solid and dependable underwater. Every Helius Sealux unit undergoes 100% underwater pressure testing before shipment to ensure zero water leakage.
