Should LEDs be used in enclosed fixtures?

There are LED light bulbs available that can be used in enclosed fixtures.  However, the majority of LED bulbs will indicate on the package that they are not to be used in fully enclosed fixtures.  Using an LED light bulb in an enclosed fixture when it is not recommended by the manufacturer may cause the bulb to overheat and fail early.  It is important to read the packaging carefully to find out what type of fixture the bulb can be installed in. Also the packaging should say if the bulb is meant to be used indoor or outdoor and if it is designed to be used in wet or dry locations.
