System overview
The SS184MKII combines continuous illumination, strobe operation and an optional adjustable laser for inspection imagery. Independent control options allow it to work with a camera or external controller. The August 2025 datasheet identifies SS182MKII aluminum and SS184MKII titanium versions; their depth and mass values must be distinguished when ordering.
Applications
- Subsea video illumination
- Image scaling with laser option
- Inspection-system strobes
Key features
- Approximately 11,000-lumen continuous output.
- Strobe output up to 14,000 lumens for 1–100 ms.
- Constant-current LED drive with configurable dimming.
- Analog, digital and serial controls.
Technical details

Configuration options
Laser geometry and outputOptical option
Select line, split or spot geometry and output. Laser is an option; confirm the delivered laser class and operating instructions.
Color and controlElectrical option
Select 4000/5700 K, interface, strobe trigger and factory connector.
Compatibility and naming
Source contains conflicting aluminum depth ratings, malformed wavelength/efficacy notation and unlabeled titanium mass values. Model-specific laser manual and confirmed pressure rating remain required. Published shared Dark Saber photo depicts the aluminum housing; exact titanium model photo is not independently identified.
Datasheets & documentation
SS182MKII / SS184MKII — Dark Saber — specification
Applies to the named models and revision only. Housing, interface and performance differences must follow the individual model tables. Source discrepancies are recorded on the ROVITEC product pages; request the approved specification before integration.
