LED technology has advanced towards use in high intensity lighting purposes. LED luminaires have a significantly longer expected lifetime than traditional high-intensity discharge lighting systems. Due to these recent improvements in LED technology, there is a growing need for a comprehensive method to analyze the applicability of LED luminaires for use on major routes and roadways. This research investigates the acceptability of LED luminaires for use on major roadways through a feasibility analysis using data collected at various LED street light testing sites. Nine distinct LED luminaires were analyzed in field testing. The field data was then analyzed and compared to manufacturer's claims, or values produced by the manufacturer's IES file. Sustainability was incorporated through an economic analysis, environmental impact analysis, and a stakeholder analysis. Each of the nine luminaires in the field feasibility study were also economically analyzed. An economic life cycle approach was used to analyze the economic requirements for each luminaire. The life cycle approach includes cradle to grave costs, including installation costs, operation and maintenance costs, and removal and disposal costs. A sensitivity analysis was also performed to identify the most critical variables within the life cycle analysis. The increased electrical efficiency provided by LED luminaires causes a decreased environmental impact through reductions in CO₂ production and reduced water consumption. Social sustainability was analyzed through the discussions and interviews with the penultimate end users, state and local agencies. Plans for testing products for future implementation are also discussed.
