Abstract
A lamp that houses an illumination source such as, for example, a number of light emitting diodes (LEDs), is selectively adjustable to vary the length of the lamp to accommodate a number of installation types and configurations. The single lamp housing design meets all the required lamp standards and can be used interchangeably within fixtures requiring differed lamp lengths. The lamp includes a base that is configured to be coupled to a power source of a lamp fixture. The lamp has a neck coupled to the base and a housing arrangement this is movable relative to the neck that can move between an extended and retracted position via a guide arrangement.
