Lighting - Led Description: Save the planet while lowering your electricity bill by switching out your trusty incandescent bulbs for their LED counterparts. While LED bulbs are significantly more expensive than a normal bulb, they tend to last longer, burn out less frequently, and use up less electricity to do their job.But what exactly is an LED bulb?Since being patented by Thomas Edison in 1879, the lightbulb has gone through minimal changes throughout the years. Traditionally, lightbulbs worked byconducting electrical current passes through a thin metal filament wire, heating it to a high temperature until it glowed and lit up. The hot filament was protected from oxidation by a glass or fused quartz bulb that was filled with inert gas or a vacuum. These lightbulbs produced both heat and light, and became the gold standard for lighting fixtures until CFLs came into the scene.CFLs orCompact Fluorescent Lights worked differently to incandescent bulbs. Instead of running an electric current through a wire filament, they drive an electric current through a tube that contains argon and mercury vapor. This process creates ultraviolet light that quickly translates into visible light, unlike incandescent lights which put off a warm glow. CFLs use up to 70% less energy and last years longer than incandescent bulbs. However, they do take a few minutes to warm up and reach full brightness, making them ill-suited to areas where you'd want lots of light instantly, like dark, steep basements or stairways.
