When Thomas Edison finally found the right filament to create the first light bulb the incandescent light bulb was born. Incandescent lighting is the result of electricity passing through a fine filament which then heats up and light is produced as the result. This has been the standard for many decades and has proven to be reliable and easy to work with. C9 incandescent bulbs have been around for generations and continue to give consistent reliability and performance.
