DESCRIPTION

The 20K Lumen LED Light is our most powerful and advanced subsea lighting solution, specifically engineered for Work-Class ROVs operating in the most demanding environments.

At its core, the light features 4 fully independent and redundant LED modules, each with its own dedicated current regulation and thermal management. This architecture ensures that if a single module were to fail, the remaining modules continue operating unaffected, maintaining illumination and minimizing mission risk. This design draws from the proven electronics of our 5000 and 5001 Series, offering unmatched reliability and service continuity.

To protect against overheating, the light includes an advanced over-temperature failsafe:

At 60°C internal temperature, output is automatically limited to 50% to allow thermal recovery.
At 65°C, the light safely shuts down and becomes non-responsive to dimming inputs, protecting the core electronics.

Despite its extreme brightness, the light maintains flicker-free operation even when powered by AC mains voltage using triac phase-cut dimming. This is achieved through our proprietary driver design, which filters and stabilizes the input to ensure a clean and constant light output, critical for HD video inspection and photogrammetry
