Solid state lighting isn’t coming. It’s already here.
Look at the construction specifications for any large commercial project and you will find LEDs and, increasingly, lighting networking, as an integral part of the plan. It’s a no-brainer. Energy efficient buildings achieve rents that are 4% to 13% higher than conventional buildings and achieve capital valuations that can be 3% to 25% higher than their normal counterparts. Lighting accounts for 14% of all energy used in commercial buildings and LEDs are key in maximizing these returns.
Cities are rapidly converting to LED streetlights for many of the same reasons. LED street lights can reduce power consumption by over 70%. Just as important, they last for decades, dramatically reducing maintenance hassles and outages. In Paris, solid state streetlights are being equipped with networking to dim lights after 1 p.m. to reduce light pollution. LiFi, an emerging standard for transmitting data via solid state lighting sources, is already being studied as a mechanism for sending real-time information about traffic jams.
The Department of Energy estimates that solid state lighting is on track to cut lighting power by 46% by 2030.
The last frontier is the home. Homes are a little more challenging than commercial buildings. Energy savings can’t be as easily monitored and homeowners don’t think of lights in the context of total cost of ownership. But the picture is changing. Consumer reports noted that an LED bulb can save you $100 to $400 over its lifetime. LED light fixtures and bulbs occupy much more shelf space in big box retailers than they did two years ago.
