The BIRNS Snooper III™, BIRNS model 5570, (NSN 6230-01-025-5628) is the newest model of this popular, intensely brilliant 3km-rated 3250K underwater light. Launched in 2012, and unmatched in durability and dependability, the BIRNS Snooper III is available with a new backwards compatible conversion kit. It has an innovative new lamp, reflector, base and lamp base mount, providing seamless adaption for most legacy systems. There are tens of thousands of existing BIRNS Snooper systems in the field—many of them on vehicles and used by divers—still working perfectly since the 1960s.

This incredible multi-purpose light blazes with up to 33,000 lumens and has a choice of 400 to 1,200W lamps and four different lens options—so it’s perfect for a vast range of marine and deep sea applications. With a robust, bulletproof lens and reinforced tempered cast body, it can be hand held or yoke mounted to practically any surface or vehicle for decades of powerful underwater illumination.

The system includes choice of white light lamp, lens, and mount, with an available handgrip that is now detachable—plus, the BIRNS Snooper mounts on its mounting boss for maximum space savings and versatility. It features an instant ON/OFF and hot-restrike capability, with no ballast necessary and comes complete with a detachable CEF3S power cable assembly.


The BIRNS Snooper is used by divers, on diving bells, submarines and ROVs across the world, thanks to its extremely rugged fixture, proven to stand up to heavy mechanical abuse. This customizable light also provides immensely powerful illumination options for underwater filming and photography.
