LED's warrants for a long life while an external power supply is not necessary

Designed to set a new standard in green construction for the Alfred University campus, Ann's House was designed to be certified at the Silver level or above by the U.S. Green Building Council's Leadership in Energy and Environmental Design (LEED) Green Building Rating System. In addition to the energy-efficient LED and fluorescent fixtures that light the 48 student bedrooms, hallways, lounges and stair towers, Ann's House also features led high bay light televisions, high efficiency boilers and instant hot water heaters, natural stone and cement composite siding and low VOC (volatile organic compound) materials used for flooring, paints and building materials. The building is equipped with solar panels to provide approximately 8% of the electrical demand during daylight hours.

"LED lighting can be an effective way to help commercial buildings like Ann's House gain valuable LED points," said Deb Lovig,YAHAM LED programs manager. "Joining YAHAM's LED University program makes Alfred University a model for other schools looking to deploy LED lighting."

The unit uses high brightness white LED's and fibre optics, lighting not just the key legends, but also the key edges, the trackball contour and even possible customer logo's or trademarks. Using low power LED's warrants for a long life while an external power supply is not necessary; the power from the keyboard port being sufficient.  The illumination intensity is easily controlable by two dedicated UP and DOWN keys.  This illumination setting is stored at power off.  Furtheron it features an intelligent luminosity setting of the “numlock” and “capslock” LEDS depending on ambient light and key brightness setting. The keyboard uses short travel switches with low pressure and positive tactile feedback.
