The LED SeaLite meets the demands for the market challenges of today. This subsea light emits up to 10,000 lumens and is available in multiple LED, beam pattern, input voltage, and depth configurations.

The standard sapphire port has a 6,000 m or 11,000 m depth rating and the optional acrylic port has a 4,000 m depth rating. The LED SeaLite includes a mounting bracket with titanium inserts.

The LSL-1000 and LSL-2000 models have a wide range of accepted voltage inputs as well as a low inrush current. Both digital and analog dimming interfaces support flicker-free dimming. This light comes standard with intelligent thermal protections that always put out the maximum light for the current operating temperature.

The LSL-2025 adds Multiray® technology to incorporate two sets of LED sources in a single fixture.

Monochromatic LED options and a range of white temperatures are available. Contact us to discuss your specific lighting needs.

This light is field serviceable with no solder wire connections or specialized tools required. The LED SeaLite includes a two-year limited warranty.
