• LED light bulbs are actually a cluster of smaller light emitting diodes that produce light.

LEDs have no filament and that makes them more resistant to heat, cold and shock.

• An LED is a "solid-state lighting" technology, or SSL. Rather than emitting light from a vacuum, which is what an incandescent bulb does, or a gas, which is what a fluorescent bulb uses, an SSL is able to emit light from a semiconductor.

• As the electrons move around they produce light but not heat, and because of the structure of the product these lights are more stable and last much longer.
