100-year-old light bulb still works EAST CLEVELAND, Ohio, March 27 (UPI) -- GE Lighting said a 100-year-old light bulb from a time capsule uncovered at its Nela Park facility in Ohio still shines. The company said the time capsule containing five incandescent light bulbs was unearthed Monday as part of the run-up to the East Cleveland facility's 100th anniversary celebrations in April 2013. It was discovered one of the 40-watt bulbs still glowed when inserted into a special socket, The (Cleveland) Plain Dealer reported Tuesday. The time capsule, a lead box in the cornerstone of one of Nela Park's original buildings, also contained photos of Nela Park's founders, journals, a book of technical specifications, and a 100-year-old edition of The Plain Dealer. Nela Park, thought to be one of the country's first industrial parks, was founded as a research facility for General Electric and still houses more than 700 employees working to further the advances of GE Lighting.
