Li-fi can deliver internet access 100 times faster than traditional wi-fi, offering speeds of up to 1Gbsp (gigabit per second).
It requires a light source, such as a standard LED bulb, an internet connection and a photo detector.
It was tested this week by Estonian start-up Velmenni, in Tallinn.
Velmenni used a li-fi-enabled light bulb to transmit data at speeds of 1Gbps. Laboratory tests have shown theoretical speeds of up to 224Gbps.
It was tested in an office, to allow workers to access the internet and in an industrial space, where it provided a smart lighting solution.
One of the big advantages of li-fi is the fact that, unlike wi-fi, it is not prone to interference, so could be utilised on aircraft and in other places where interference is an issue.
While the spectrum for radio waves is in short supply, the visible light spectrum is 10,000 times larger, meaning it is unlikely to run out any time soon.
But the technology also has its drawbacks - most notably the fact that it cannot be deployed outdoors in direct sunlight, because that would interfere with its signal.
