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.
