Refined and more powerful the 9470 Remote Area Lighting System (RALS) provides convenient and ecologically responsible alternatives to wasteful generator powered lights. Engineered with the Intelligent Control System which calculates and displays current battery life, allows the user to regulate the intensity of the light and choose the desired run time. Built with versatility in mind, the 9470 RALS features four swiveling telescope masts (each extends to nearly 6 feet) and four 360 degree articulated light arrays. The system's next-generation LEDs combine to radiate up to 12,000 lumens (3,000 per light head). Powered by a set of rechargeable batteries , the system offers up to 7 hours of peak brightness with a variety of extended run times. Built self-contained in a tough-as-nails Pelican case, the 9470 is compact and provides easy ground transport with a pull handle and stainless steel ball-bearing, polyurethane wheels.
