To me they were the best lighting tech on the market as the appearance was very much like coated mercury lighting - Philips QL lamps, they still use them at Reading railway station to this very day thank goodness. The QL lamps wee used for LPA airport in Gran Canaria, sadly didn't get a pic as I was very poorly on the way back home

South Kensington area of London, nearby Royal Albert Hall have these induction streetlights with the rectangular shaped tubes . Oh and one of my uni halls had the lowbay lights with the same rectangular tubes in them
Saw some decent looking floodlights with the rectangular shaped tubes too - to sum it all up - MUCH BETTER THAN LED I WISH INDUCTION TOOK OVER INSTEAD OF THE WRETCHED LED
