SLS series high energy efficiency LED lights, ultra-low power consumption, brightness more than five times of ordinary halogen lamps, working life of 50,000 hours, maximum output lumen up to 11,000 Lux, maximum working depth up to 11,000m, high seismic capacity, small volume, is the world's most efficient light output underwater LED lights. It is suitable for all kinds of harsh working environment, for underwater observation, lighting of pipeline inspection and other strong vibration occasions. At present, it has been successfully applied in the domestic project of 7000m jiaolong and 11000m undersea lander.
