Northumberland-based i-glo's David Oliver says the glow in the dark landscaping product, which uses patented photoluminescent technology to light up path edging and stepping stones has received a substantial order arising from Glee from a major garden centre chain.
He said there was interest from six big supermarkets and interes from the US, France, Germany and Sweden in the Glee award winner.
Oliver said: "We have spent a lot developing public awareness. This could be a market worth tens of millions. It's not just limited to landscaping."
The company has changed direction to concentrate on i-glow after the Indian sandstone market suffered from cheap imports.
