I agree JMB...Tax credits and incentives are a huge carrot being dangled in front of building owners to jump on board and change out existing lighting for energy efficient LED lighting.  "According to the U.S. Department of Energy, lighting represents 40% of the average commercial building’s electric bill. Responding to demand for more-efficient solutions, the lighting industry developed a wide range of energy-efficient products that can significantly reduce lighting energy costs while maintaining or potentially improving lighting quality. In new construction, energy-efficient lighting is the norm due to tightening energy codes. In existing buildings, older, obsolete systems are being upgraded as availability of older systems is eliminated by product regulations. The Energy Efficient Commercial Buildings Tax Deduction was created to enhance the financial attractiveness of investing in the most energy-efficient lighting and other building technologies."
