A lamp including a lamp base having at least three electrical contacts, an optical housing with an LED light source distal from the lamp base, a capper assembly including two or more bias switches accessible by a user located between the lamp base and optical housing, electronic circuitry located within the capper assembly, the electronic circuitry electrically coupled to the three electrical contacts and the LED light source, the electronic circuitry configured to provide a drive current to the LED light source, and the two or more bias switches are user-settable to set the drive current. The electronic circuitry provides at least two different levels of drive current to the LED light source, where the two or more bias switches are configured to control multiple levels of LED light intensity to an individual level.
