Scottish startup PureLiFi has announced a £1.5 million ($2.25 million) funding round — valuing the company at £14 million ($21 million) — as it looks to introduce Internet connectivity via light bulbs around the world.

Founded in 2012, PureLiFi — previously known as PureVLC — is a spin-out from the University of Edinburgh in Scotland’s capital, and is led by Professor Harald Haas. During a TED talk he gave back in 2011, Haas popularized the term “Li-Fi” to describe networked, bi-directional, wireless communication that uses visible light instead of traditional radio frequencies.
