Halogen light exist since a long time. It is an incandescent lamp consisting of a tungsten filament and a tube that is filled with a mixture of an inert gas and a small amount of a halogen such as bromine or iodine. The history goes back to 1882, but in 1959, General Electric patented a practical lamp using iodine.
