Abstract
An LED lamp having a lamp housing including a lamp base capable of connecting to a source of electrical power and at least one LED lighting device having at least one LED, the lighting device being electrically connected to the lamp base offset from a center line running vertically through the center of the housing. The lamp further includes at least one optic having at least two sub-optics, each sub-optic capable of allowing a different beam angle of light distribution to pass there through when aligned with the LED lighting device, the optic being integrated with the lamp housing such that the optic may be rotated to align one sub-optic over the LED lighting device at a time.
