LEDs operate by electroluminescence, a phenomenon in which the emission of photons is caused by electronic excitation of a material. The material used most often in LEDs is gallium arsenide, though there are many variations on this basic compound, such as aluminum gallium arsenide or aluminum gallium indium phosphide.
LEDs that are used in fixtures where there's less than 1/2 around the circumference of the lamp when installed in the fixture are also considered an enclosed application. If you plan to use LEDs in these types of applications you should use an LED that's rated for enclosed fixtures. Using an LED lamp not rated for enclosed fixtures in this type of application may cause the LED lamp to flicker and will dramatically reduce the life of the lamp.
