LED Retrofit Options for Linear Fluorescent Lighting

摘要

While payback periods are very long for short-term economic goals, life-cycle cost comparisonsthat consider long-term economic goals provide a significantly different perspective. The average incremental life-cycle cost of new LED luminaires is about $150 more than the life-cycle cost of staying with TFLs. Over 50,000 hours of operation, this translates to $0,003 per operating hour, or about $.03 per day (given a 10-hour day) for all of the benefits of a new LED luminaire, i.e., appropriate CPD and SPD, high CRI, and increased chances of meeting light output and life expectations through proper thermal management.
