The City of Henderson in partnership with McKinstry, a design-build company specializing in energy-based retrofits, will replace more than 6,200 light fixtures across the city with energy-saving LEDs that will pay for themselves in just over seven years.

The new branch office for the National Bank of Arizona in Prescott is the first in the state to install new energy efficient LED lighting and HVAC technologies from LG Electronics and advanced control systems from Daintree Networks, Inc. Within the 3,000-square-foot facility, slated for completion in June, Daintree's ControlScope solution will manage 13 lighting zones controlling LG's industry-leading LED fixtures and nine thermostats controlling LG's highly efficient variable refrigerant flow (VRF) air conditioning system.

More and more American cities are being installed with LED light fixtures with embedded cameras and sensors. Newark airport is the latest among the long list of areas investing in surveillance technology in combination with LEDs. The newly installed LED fixtures are connected to a wireless surveillance system to provide safety for fliers and cut down on operating costs. Around 171 LED fixtures have been installed around the airport so far.
