LIGHT EMITTING DIODES (LED)
The term LED is an acronym for "Light Emitting Diode". LEDs are a semiconductor light source and do not contain a filament. LEDs are a solid state light source unlike traditional lighting sources which contain a vacuum tube. Unlike traditional light sources LEDs are highly efficient in terms of light delivery and have very little wasted light.
LEDs have many other advantages over traditional light sources including lower energy consumption, longer lifetime, durability and robustness, smaller size, and versatility. Imagine a light bulb that you install into a fixture and it pays for itself in electrical savings multiple times and requires no maintenance for years or decades. LEDs represent this kind of lighting technology.
LEDs are the most energy efficient, durable, longest life light source available of all lighting technologies and will pay for themselves many times over the life of their investment. LED is the future of lighting.
Below is an example of the savings and life of a 10 watt LED vs. a 75W A19.
1 A19 LED Bulb = 30 Incandescent Bulbs = 20 years at 4 hours per day.
1 A19 LED Bulb = $175 saved over the life of the bulb @ $.09 per kWh
