The arrival of highly efficient LED lighting offering more than 100 lumens per watt, and the dramatic fall in LED prices over the past three years has led to a single minded focus on energy savings and rebates, life-time cost and ROIs of under a year. LED lighting retrofits have become basically free. With this remarkable incentive, LED lighting installations are projected to exceed 50% of the market before 2020.   This amazing growth in efficiency and energy savings is wonderful, but there is another side that’s not so amazing or wonderful.
