The United States Institute of Peace in Washington, DC, features a pervasive lighting theme built with GE T5 fluorescent lamps. Light sources are fully concealed or designed to disappear, revealing and animating, but never competing with the architecture. This weekend is the last chance to submit photos of your favorite landmarks and lighting with the hashtag GELights, for the chance to win a trip to London and a lighting home makeover from GE! Post your photos by August 12th to enter, and vote for your favorites through August 19th. The photo with the most likes will win!
