BIRNS, Inc., an ISO 9001:2008 certified global leader in the design and manufacture of unique lines of high performance lights, connectors, penetrators and custom cable assemblies for severe environments, has introduced the ultimate underwater security light: the new BIRNS Pisces™.
This rugged, 130,000 lumen High Pressure Sodium Vapor (HPSV) lighting system is designed for a range of underwater security applications and for use alongside military submarine docks, but can be tailored for many different applications where long term use, extremely powerful illumination and minimal maintenance is required.
The BIRNS Pisces’ robust construction features a solid housing fabricated of 63AA-electropolished AISA type 316 stainless steel. With a tough 1.06” thick tempered glass lens further supported by stainless steel reinforcing bars, this incredibly durable and powerful system is custom-engineered to withstand long term immersion in seawater. The 1kW HPSV lamp operates in a dry, one atmosphere chamber, and has a 24,000 hour lamp life—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, tool-free, by hand in 60 seconds, 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.
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. In fact, the lamphead has a pan and tilt mouthing yoke, for maximum versatility.
