![]() ![]() Though more efficient than the incandescent, it had limited use due to its color spectrum. Peter Cooper Hewitt In the early 1900s, Hewitt created a blue-green light by passing an electric current through mercury vapor and incorporating a ballast to regulate current.The Geissler tube, a discharge lamp, remained in the dark until the early 20th century when researchers began looking for ways to improve lighting efficiency. Henrich Geissler and Julius Plucker These 19th century German inventors discovered the ability to produce light by removing almost all of the air from a long glass tube and passing an electrical current through it.The technology of compact fluorescents has progressed thanks to the hard work of many inventors in fluorescent light technology over the years… Though the idea of fluorescents has been around since the 1880s, it wasn’t until the 1930s that they were developed for commercial use. The history of compact fluorescent light bulbs Fluorescent light bulbs, including compact fluorescent light bulbs, are comprised of a large family of light sources including cold cathode, hot cathode, and electroluminescent. One of the greatest developments in lighting since the 1879 incandescent, recent advances in technology and drastically reduced costs have compact fluorescent light bulbs flying off the shelves. ![]() Long-lasting and energy efficient, compact fluorescent light bulbs (CFLs) offer consumers an affordable alternative to the incandescent in today’s ever-demanding race to go green. ![]()
