on december 31, 1999, a powerful beam of light was unveiled for the first time. called the legacy light or skybeam, it is powered by lamps that total 85 million candela shining skyward from the top of the space needle to honor national holidays and special occasions in seattle. the concept of this beam was derived from the official 1962 world's fair poster, which depicted such a light source although none was incorporated into the original design. it is somewhat controversial because of the light pollution it creates. originally planned to be turned on 75 nights per year, it has generally been used fewer than a dozen times per year. it did remain lit for eleven days in a row from september 11, 2001, to september 22, 2001, in response to the september 11, 2001 attacks.
