Puget Sound Energy ,Washington state’s oldest local energy utility, has provide a new instant rebate for up to $10-off led high bay light for residential electric customers. It is PSE’s first LED bulb rebate for residential electric customers.

PSE customers can receive an instant rebate of up to $10-off a variety of ENERGY STAR-qualified LED bulbs. Depending on the type of bulb, the after-rebate price to customers ranges between $15 and $50. Customers can purchase rebated ENERGY STAR-qualified LED bulbs at participating retailers including Costco, Lowe’s and The Home Depot.

In 2010, PSE was among 14 utilities and energy efficiency organizations to partner with the U.S. Department of Energy’s Bright Tomorrow Lighting Prize (L Prize) competition to field test energy-efficient LED bulbs to replace the standard 60-watt incandescent bulb.

All studies were conducted using blind samples of GT ASF sapphire material as well as LED grade sapphire from other sources. The case study results were obtained from an independently conducted Glow Discharge Mass Spectroscopy (GDMS) analysis as well as a High Brightness (HB) LED device fabrication study performed using Photo-thermal Common-path Interferometry (PCI) analysis.
