The World Usability Day (WUD) project will make 1,000 LED spot/bulbs available for free via their website www.worldusabilityday.org. "Assume the following math: 1,000 bulbs can replace all of the light bulbs in 20 medium-sized houses," said Brian Sullivan, the usability principal at the Sabre Human Factors Center in San Francisco, CA, and co-chair of World Usability Day. "The LED bulbs are easily three times more efficient than standard bulbs. So that is the equivalent of lighting 100 houses," said Brian Sullivan, co-chair of World Usability Day.

The WUD free light bulbs will be offered worldwide. The project is being made possible by Next Generation Lighting Supply and Seoul Semiconductor, Inc.. NGL Supply will provide the bulbs with Edison bases (standard in most lamps, ceiling fans, and recessed lighting outlets) and fulfillment, and Seoul will supply the inner workings. WUD web site visitors will fill out a form with a DISCOUNT code. When the visitor clicks a button from the WUD site (after filling out a form), they are taken to the NGL site for fulfillment. Participants will pay for shipping and handling (which is very common for FREE items).

The Fifth Annual World Usability Day will be celebrated globally on November 12 with the theme "Designing for a Sustainable World." Countries that announced WUD projects last week included Estonia, Egypt and the United Arab Emirates bringing the total number of countries to 38 and the number of events to 112.
