Most recently CoeLux was awarded the “Light Source Innovation of the Year” at the 2014 Lux Awards. It’s important to note that this is the first iteration and improvements will come. In an informative review, LuxReview.com adds:

“The void height needed is a metre. It consumes 340W of electrical power, but that will come down as LEDs improve… CoeLux is at the beginning of its commercial journey, and that’s reflected in the current cost. It’ll set you back £40,000 from the factory gate, and another £3,000 to £5,000 for shipping and specialist installation. But the interest is already there, particularly for high-value underground installations”
