LED light bulbs are carefully packaged arrays of light emitting diodes (LEDs). These simple LEDs are solid state devices which produce light through a process called "electroluminescence." They do this by moving electrons across a very special gap within their internal construction that gives off photons when electrons enter the gap. These photons are the light we see and are different colors based on what materials are used to make the LED. LED bulbs use arrays of multiple LEDs along with special reflectors to replicate the patterns and brilliance of standard lights in many shapes and sizes
This method not only produces far less heat, but it generates an equivalent amount of light for roughly 80% less energy than a traditional incandescent lamp. Without a filament or glass bulb, an LED light bulb is also more durable and longer lasting than any incandescent can be.
LEDs are one of today's most promising lighting technologies. The best claims made by LEDs are:
•No mercury, making them a cleaner alternative to fluorescent and CFL lamps.
•The lowest energy consumption of any lighting product to date.
•Light quality equal or superior to traditional lighting products.
•Life that is 20 times than some traditional lighting products
