The history - how it all began
The IQ lightTM system was designed in 1972 by Danish designer Holger Strøm, who was then working at the Kilkenny Design Workshops, Ireland.
He was originally asked to create a modular construction for a cylindrical and a spherical lamp, both to appear to be the same size, to be used in a Christmas display.
"I constructed them from triangular modules, which I glued together, and by using an equal number of modules for the sphere and the cylinder, they did actually appear to be the same size. It was just a Christmas decoration, but I couldn't completely forget the idea. I wanted to make it with a mechanical assembly system, and with identical modules.
"I used a rhomboid shape because, of the classic geometric shapes, it's one that can give a most round form. I also realised that by giving the module a curl on each corner I could hook them together, but the result was a bit loose and floppy. So I lengthened the top and bottom of the rhombus, that gave them tension when they were hooked together, and it was that tension I needed for the lamp to hold together."
Through the seventies it was manufactured by Kilkenny Illuminations Ltd, who sold around 20,000 lights worldwide.
