Teledyne Bowtech, a division of Teledyne Limited, will supply modified LED-V-Series deep water lamps for installation on board Triton submarines for the Five Deeps Expedition.
The Five Deeps Expedition is a collaboration between investor and explorer Victor Vescovo of Caladan Oceanic, Triton Submarines and EYOS Expeditions.
The Five Deeps Expedition is launching as the first global ocean journey to send a manned submersible vessel farther and deeper than any in history, the company said.
A two-person deep sea research submersible, named the Limiting Factor, has been designed specifically for this endeavour.
It will be transported and deployed into the ocean depths by the Pressure Drop, a ship retrofitted for the expedition.
The mission includes dives to the Puerto Rico Trench (Atlantic Ocean 8,408 meters), the South Sandwich Trench (Southern Ocean 8,183 meters), the Java Trench (Indian Ocean 7,290 meters), the Mariana Trench/Challenger Deep (Pacific Ocean 10,925 meters), and the Molloy Deep (Artic Ocean 5,573 meters).
Teledyne Bowtech were commissioned to design a bespoke lamp, designed to operate in up to 11,000 meters of seawater and with a lumen output of 15,500.
Developed from the standard LED-V-Series lamp, the LED-1153, constructed from hard anodised 6082-T6 aluminium and 316L stainless steel, is pressure compensated with silicon fluid and has a maximum operating depth of 11,000 meters.
