Your Trusted Partner for Diving
The D26 2800 is a high-intensity dive light delivering 2800 lumens output with a 7° ultra-narrow beam.
It achieves a 450m throw to penetrate murky waters effectively.
Powered by a USB-C 21700 battery, it delivers a 1.5-hour runtime in high – brightness mode.
It’s perfect as the primary light for recreational diving, and serves as a reliable backup light for technical diving.

Key Takeaway: Real-world high-mode battery life consistently falls between 80–90 minutes across both bench tests and in-water dives, closely matching the claimed 1.5 hours. Low mode extends beyond 4.5 hours for all-day use. Most critically, cold water (5–8°C) does not trigger any output reduction — the light maintains full power until the battery indicator turns red, a performance rarely seen in this class.

Key Takeaway: The 7° ultra-narrow beam delivers class-leading penetration across every tested environment — from clear open water to murky lakes and silt-filled mines. Testers consistently reported that the focused spot cuts through particulates far more effectively than wide-beam alternatives, with verified throw reaching 26 meters in daytime and 450 meters rated.

Key Takeaway: In head-to-head underwater tests, the D26 2800 visibly outshines the Orcatorch D520 in brightness, and delivers superior focus compared to Scubapro Nova 850R, DGX600, and Big Blue TP4800P — particularly for long-distance signaling during DPV scootering. The D26 holds its own against established brands with a focused beam that testers consistently preferred for targeting and communication.
