Helios-100K CoreLite™
Master-Lee’s Helios-100K CoreLite™ is a high-power reactor core plate light delivering up to 110,000 lumens of dispersed white LED illumination. It fully lights the entire core plate from a single position, reducing the need for repositioning and saving operator time. The light mounts securely via a custom pin in a core plate flow hole and can be converted into a general area light when the pin is removed.
Designed for fuel movement and video inspections, the Helios-100K™ is fully dimmable, operable in air, submersible to 100 feet, and safe for use near irradiated fuel assemblies. Its durable LED design provides thousands of hours of maintenance-free operation, with routine maintenance limited mainly to lens replacement due to radiation exposure.
PERFORMANCE
Delivering up to 110,000 lumens of dispersed, white light utilizing advanced LED technology, the Helios-100K CoreLite™ is ideal for illuminating reactor cores during fuel movement and video inspection operations.
MANUAL/AUTO-DIMMING
With the capacity to produce up to 110,000 lumens of crisp, bright light there comes a point where changing conditions necessitate adaptation and that level of intense lighting can become overwhelming and counterproductive. Fully dimmable from 100% output to 10% power gives the end user total control allowing the light to perform exactly as needed. If it’s not the user adjusting light output based on conditions, it’s the conditions adjusting light output. The Helios-100K CoreLite™ incorporates a unique safety feature, Auto-Dimming, to protect itself from thermal overload. When the Helios-100K CoreLite™ is removed from water, its primary cooling medium, its operating temperature begins to rise. As this occurs, it senses the temperature increase and begins to lower its light output to maintain a safe operating level. In the warmest of open-air working environments, the Helios-100K CoreLite™ will effectively and safely cool itself through natural convection, operating down to 60% power levels if required. When conditions require fine control over light output, the end user can adjust this via a dimmer knob located on the control box.
PORTABILITY
Constructed of hard-anodized aluminum, the Helios-100K CoreLite™ weighs 51 pounds for easy, manual installation/removal. For construction, commercial fishing vessels, or other industrial applications, we offer customized mounting options to your specifications. The Helios-100K CoreLite™ features the ultimate in portability in that all of its electronics are housed within a compact power console. Operating on standard 90VAC or 305VAC (DC input voltage is an available option) and drawing under 7-Amps adds to the portability and permits multiple lights to be configured on one electrical circuit.
