Appalachian Lighting ALLED SL4 LED streetlight
October 7, 2011 By Anthony Capkun
October 7, 2011 Appalachian Lighting Systems (ALSI) launched its ALLED SL4, boasting it is the industry’s first LED streetlight to feature a two-way internal wireless control system. The ALLED SL4 can be configured to replace 70W to 400W HID roadway Type III and V fixtures, and promises to save 75% or more on energy costs with the patent-pending ALLink control system. Appalachian insists that ALLED SL4’s performance—and the value proposition offered through financing, warranty and maintenance programs from SSL Energy Solutions—can help virtually any city cost-justify an immediate switch to 100% LED lighting. The SL4’s ALLink onboard, two-way, built-in DC-side wireless control system manages lighting levels, and monitors and reports energy usage and fixture functionality in real-time. The system can withstand multiple power surges of up to 10kVA; is engineered for more than 150,000 hours of use, and is available in 4000K to 6000K colour temperatures.
