Our solutions segment provides turnkey, high-quality, energy-efficient lighting application alternatives, which are designed to enhance total value by positively impacting customers’ profitability, the environment and the communities served. These solutions are sold through our EFLS subsidiary, and include not only our proprietary energy-efficient lighting solutions, but also sourced lighting systems, energy audits and service agreements.
