BIRNS Pisces™ Underwater Security Light
The BIRNS Pisces™ is the ultimate underwater security light—a rugged, 130,000 lumen High Pressure Sodium Vapor (HPSV) lighting system trusted in some of the world’s most demanding marine environments. This brilliant 1kW light has a 24,000 hour lamp life, and can be tailored for many different applications where long term use, extremely powerful illumination and minimal maintenance is required. Its robust construction features a solid housing fabricated of 63AA-electropolished AISA type 316 stainless steel—and with a tough 1.06” thick tempered glass lens further supported by stainless steel reinforcing bars, this powerful system is custom-engineered to withstand long term immersion in seawater.
The HPSV lamp operates in a dry, one atmosphere chamber, and in concert with its high-reflectivity mirror-finish reflector, provides intense light output. This high intensity gas discharge lamp has no filament, making it nearly impervious to shock and vibration in situ. It can be relamped by hand with commercially available, low mercury (Toxicity Characteristic Leaching Procedure (TCLP) compliant; .06mg/liter) lamps. The system comes with two robust wet mateable BIRNS connectors, with gold plated contacts per MIL-G-45204.
Brilliant and nearly indestructible, the robust BIRNS Pisces is designed for a broad suite of rigorous underwater security applications and for use alongside military submarine docks. This intensely powerful light stands up to the most punishing conditions at sea, yet it has a slim 13.2’’ wide by 19.7’’ long profile that can be adapted to many rigorous applications.
