1. A light engine for a lamp, comprising:

  • a heat sink having;

    (a) a first modular-coupling for attachment of a lighting industry standard lamp base, the first modular-coupling being configured for compatibility with each of a plurality of different lighting industry standard lamp bases each configured to connect the lamp to and provide electrical contact of the lamp with a corresponding lamp socket, and(b) a second modular-coupling for attachment of one of a plurality of different types of bulbs;

    a pedestal attached to and extending from the heat sink along a longitudinal axis of the light engine into a region to be surrounded by a bulb when the bulb is attached to the heat sink, the pedestal providing heat conductivity to and being supported by the heat sink; and

    a plurality of solid state light emitters configured to emit light,an end portion of the pedestal to be surrounded by the bulb having;

    at least three substantially flat surfaces facing outward from the longitudinal axis of the lamp in different directions each supporting one or more of the solid state light emitters for emission of light in a different orientation, and an end face facing at least substantially along the longitudinal axis of the lamp supporting one or more of the solid state light emitters for emission of light on or about the longitudinal axis of the lamp, such that emissions outward from the pedestal from the solid state light emitters through the bulb when the bulb is attached to the heat sink approximate light source emissions from a filament of an incandescent lamp.
