Life-Cycle Energy Consumption of Incandescent CFL and LED Lamps Incandescent
Wireless in S.D. In a project the city of San Diego claims has paid for itself immediately, the city has implemented an intelligent and wireless LED street lighting system which not only better serves its citizenry, but opens the door for revenue generation.

IN EVALUATING LIGHTING TECHNOLOGIES, START WITH AN UNDERSTANDING OF AN OWNER’S GOALS, INCLUDING LONG- AND SHORT-TER M COST TOLER ANCES.
Cosio-Azar presented the project at a press event at the show. She worked closely with the manufacturer to modify its GPS and Cloud-based Lightgrid controls system and area fixtures from a more standard cobrahead-like offering to a custom luminaire more in line with those in its Gas Lamp district. The project began as a pilot, but the Cosio-Azar points out the city will be rolling it out city wide to 3,000 fixtures. Energy savings is estimated at $254,000 annually, but it is also allowing the city to be more responsive and efficient in the dispatch of its work crews. It may also lease the poles to cell services for further city revenues.

DOE studies have shown that LED can reduce energy use from lighting and maintain performance levels without using large amounts of toxic or rare-earth materials.

New Wave: Integrated Fixtures At Lightfair in Las Vegas, the buzz of the event was the trend for all the major manufacturers to show new lines of LED luminaires fully integrated with wireless controls, including daylight or
occupancy sensors. That was certainly the case with Cree, who demonstrated a suite of new fixtures, as well as its “Smart Cast” control system. A novel aspect of the system is that it features an
easy-to-use programming/commissioning remote to really facilitate the process. Smart Cast is available in the company’s CR series troffers, CS series linear luminaires and KR series downlights. Shown at the left is the H-E-B grocery store in Austin, Texas, which uses the CS 18 and CR 24 fixtures. The CS 18 luminaires are fully dimmable to meet daylighting initiatives at the store.
A modular system that can be custom configured, its LED panels and spotlights are adjustable to perform functions beyond ambient illumination. The fixture is also configurable in many forms.
