Helios-100K AreaLite™
The Helios-100K FloodLite™ remains a cornerstone of Master-Lee’s product lineup, renowned for its unmatched brightness and radiation tolerance. With proven versatility, this reliable LED light operates efficiently in both submerged and open-air environments. It continues to be the trusted choice for industries like commercial nuclear power, marine, subsea, transportation, and construction, offering consistent performance in the most demanding settings.
PERFORMANCE
With an output of up to 110,000 lumens, the Helios-100K AreaLite™ provides wide-beam, dispersed white light using the latest in LED technology. Ideal for underwater applications such as reactor cores and spent fuel pools, as well as in-air environments like refueling cavities, this light ensures superior visibility for inspections, maintenance, and operational tasks.
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 AreaLite™ incorporates a unique safety feature, Auto-Dimming, to protect itself from thermal overload. When the Helios-100K AreaLite™ 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 AreaLite™ 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 AreaLite™ weighs 29 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 AreaLite™ features the ultimate in portability in that all of its electronics are housed within a compact power console. Operating on standard 110VAC or 220VAC (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.
