Three U of T grads have invented the world’s most energy-efficient light bulb. The NanoLight, which they call a breakthrough in LED lighting technology, uses only 12 watts of electricity yet generates over 1,600 Lumens (the equivalent output of a 100-watt incandescent bulb). The inventors say that if you burn the bulb for an average of three hours a day, it would last for up to 20 years.

Launched on January 7, the team has gained about 2,500 backers and raised $125,000 so far. The first batch of bulbs is schedules to ship out in May.

The three inventors first became acquainted at the University of Toronto, where they worked together on the university’s solar racing car team. Gimmy Chu, who received his Bachelor of Science degree from the university, is co-founder of the company that invented the bulb. His two colleagues, Christian Yan and Tom Rodinger, studied science and engineering during their time at U of T.
