History of the Light Bulb

Incandescent and existing lighting fixtures use designs that date back to Edison’s days. Replacing the old bulbs with LEDs is only the tip of the iceberg when it comes to saving energy on lighting. LED lighting systems designed to take full advantage of LED’s strengths have even greater energy-savings potential than forcing LEDs into 19th century fixtures. It’s hard to tell where lighting technology will go in the future, but one thing is clear: it won’t be your grandfather’s light bulb.
