Since the first light bulb was invented in the 1800’s new lamp technology has evolved. When the fluorescent tube was invented in 1929, sales of traditional light bulbs plummeted, and then in the 1970’s along came the compact fluorescent, since then new variations have evolved, sales of the former types have virtually disappeared, but the fundamental lamp design has remained unchanged, using a heating element to ignite gases and produce light. The use of a heating element results in energy being wasted as heat as opposed to generating light.
