New BIRNS Corona™

High Intensity, Low Maintenance 1kW Lighting System Tailored for Nuclear Fuel Pools, Inspection and Reactor Cavities

Oxnard, CA—BIRNS, Inc., an ISO 9001:2008 certified global leader in the design and manufacturing of unique lines of high performance lights for demanding nuclear containment applications, has introduced the new BIRNS Corona™. This revolutionary, high intensity lighting system provides brilliant high pressure sodium vapor floodlighting for nuclear pools, turbine inspection and reactor cavity during fuel handling, or any application where long-term use, low levels of maintenance and the most powerful illumination are required. It has unparalleled light output—132,000 lumens, with a 1kW lamp—and can be operated indefinitely in air, and immersed in cold water without damage.

The BIRNS Corona is easily decontaminated and relamps by hand in under 60 seconds. Plus, it provides the lowest operating costs of any industry lighting system, with a 24,000 hour lamp life, using lamps that are commercially available for less than $300. The unique design is created for safety and longevity, with a dry, one-atmosphere chamber inside a separate rugged quartz envelope, so no water ever comes into contact with the lamp itself, and the lamp is not subjected to the pressure, thermal shock, and corrosive effect of the underwater environment. It has a unique mirror finish parabolic reflector to maximize light output and is meticulously engineered with a rugged, all stainless steel construction, including a specially reinforced captivated heavy-gauge stainless-steel mesh screen with four Ø10mm (Ø3/8-in.) solid stainless welded steel bars to increase rigidity and protect against mechanical impact.

The versatile, rugged system has type 316 stainless steel connectors sealed with redundant o-rings in a detachable subsea grade power cable assembly, providing complete mechanical protection for the electrical pins, indexed with a stainless steel keyway to prevent mismating.
