Lifetime
LED bulbs have a much longer lifespan than their traditional counterparts. Some can be expected to last around 100,000 hours, or 11 years, of nonstop, continuous operation. If only used half of each day, they can last for more than two decades. That is an incredible contrast to the weeks or months some conventional bulbs can be expected to last. They are well suited for use in difficult to maintain spaces such as stairways and stairwells.
Size
LED lighting starts with a tiny diode and LED “packages” may contain one or multiple diodes. A single LED is very small, and most LED lighting incorporates multiple sources into arrays.
Typical LED bulbs range from 3-8 mm long. This allows them to be used in a variety of different fixtures and locations. They can fit in places typical bulbs cannot squeeze and can keep a low profile for minimal distraction. Their low profile means they can be easily concealed for use in under-,over-, and in-cabinet lighting. Also available in shapes similar to incandescent bulbs, lEDs can be used as direct replacements in table lamps and many other incandescent fixtures.
