the significant energy savings inherent in the LED tronics LED bulbs that the city has already started to enjoy

According to city officials, the LEDtronics LED bulbs were selected because of their high efficiency, appropriate 3000K color temperature, and because they fit inside the existing globe diffusor without significant modification. The new led linear high bay light also allowed for the elimination of the HPS bulb's ballast and starter. As well, LED bulbs produce little or no ultraviolet light (UV) which, as generated by the HPS bulbs along with the high heat, causes the polycarbonate globe diffusers to yellow and become brittle.

With longer life for the globe diffusers and reduction of visits to each light by maintenance staff, the 10-year projected cost savings is expected to reach $150,000. This is in addition to the significant energy savings inherent in the LED tronics LED bulbs that the city has already started to enjoy.

According to Hsu Hung-sheng, a lawyer for the Japanese firm, said his client has sought damages from Formosa Epitaxy and requested the court issue an injunction to bar the Taiwanese defendant from manufacturing and selling the disputed LED products.

Additionally, not long ago, Toyoda Gosei filed another lawsuit with the United States District Court for the Northern District of California Feb. 21, alleging that Formosa Epitaxy infringed on eight led high bay light chip patents asserted by the Japanese firm.
