Nowadays, many earth-friendly homeowners have upgraded to LED bulbs. According to Energy Star, these fixtures use at least 75 percent less energy than incandescent lighting and can last 35 to 50 times longer, making them a worthwhile investment. But, as wonderful as LEDs are from a functionality perspective, they're even making their way into the world of art. 

According to BizBash, a publication for the event-planning industry, the city of San Francisco recently debuted "The Bay Lights," the world's largest LED light sculpture. Measuring in at 1.8 miles wide and 500 feet high, this piece of stunning visual beauty includes 25,000 white LED bulbs along the city's Bay Bridge. Created by artist Leo Villareal and inspired by the bridge's 75th anniversary, the energy-efficient structure is estimated to cost $11,000 a year to power and will shine from dusk until 2 a.m. for two years, featuring never-repeating patterns and formations.

"It's kind of like our Eiffel Tower of the night now," said San Francisco Mayor Ed Lee. "That bridge has been dark at night, but now there's this dazzling, bold art piece people want to come here to see. My daughter is getting married in October and already she told me, 'I need a wedding picture with that in the backdrop.'"

According to The Bay Lights's website, the installation is expected to bring in 50 million visitors and $97 million to the local economy.
