BIRNS Kelvin

Description:

Note: As of July 2019, we are discontinuing new production of the BIRNS Kelvin lines, but will still be supporting existing units with (non-lamp) spare parts and service. We will be launching a new line of LED lighting systems soon as a replacement for the BIRNS Kelvin line, in addition to our other nuclear lighting systems.

The BIRNS Kelvin™, BIRNS Model 5801, is a powerful 16,000 lumen tungsten halogen light trusted worldwide in major nuclear power stations, and is seismically-qualified per IEEE-344. It’s easily decontaminated, and relamps in just 60 seconds with a choice of wide, medium or narrow beam lamps. It mounts on a special BIRNS pan-and-tilt yoke, or hangs from a suspension assembly.

The new Model 5813 includes rugged stainless steel mesh coverings, and both feature a Lexan protector with specially designed Lexan plugs for the finger holes, and a 120V/1,000W lamp with instant on/off and hot-restrike capability. The BIRNS Kelvin requires no heavy ballast to operate, and provides tungsten halogen 2950K white light illumination. Its housing is free-flooding for high-efficiency water cooling, yet is compatible with all commercial grade Class A GFCI’s (ground-fault circuit interrupters). It is supplied with a durable 120 volt 1,000W-lamp, and has three beam angle options. Hanging weights are also available, and allow for easier suspension from the power cable assembly. The power cable assembly incorporates a rugged BIRNS underwater connector, so that the power cord can be quickly detached, without tools.

Applications:

This powerful system is designed for underwater use in areas with high levels of radiation and nuclear contamination. It’s ideal for long-term illumination of fuel pools and transfer canals, and is extensively used in reactor cavity illumination during fuel movement or other large-scale activities. It is designed to be mounted for general-purpose area light use, but can be suspended by its cable as well. It’s an excellent light for general-purpose illumination, and perfect for filming.
