Product developer Gimmy Chu told AFP the NanoLight design consists of a circuit board dotted with LED lights and folded into the shape of a bulb that plugs into a regular light fixture.

"We needed the light to shine in all directions to mimic a traditional incandescent light bulb," said Chu, who with pals Tom Rodinger and Christian Yan launched a company last year to market the product after working on it for three years.

The idea has raised more than $100,000 on a US crowdfunding website and generated pre-orders for more than 3,000 bulbs in the last month, according to Chu.

The trio is now working on a version of the bulb that can be dimmed.
