Ernst & Young Plaza Saves 80% on Electricity Bill with LED Landscape Lighting
September 29, 2007
Ernst & Young Plaza in downtown Los Angeles is decorated with a web-like truss-structure ornamented with 3,400 light bulbs. The owner of the Ernst & Young Plaza recently switched the lights with LED lights.
The incandescent lights that were replaced by LEDs had a typical life of 3,000 hours or less, which equals a useful life of about 10 months. For the Ernst & Young Plaza this meant that an average of 340 bulbs had to be replaced each day. The labor cost associated with this exceeded $10,000 each year.
The replacement LEDs will last for more than 50,000 hours or 13 years without need for replacement.
