1. A lamp, comprising:

  • a plurality of solid state light emitters;

    a bulb;

    a pedestal extending into an interior of the bulb supporting the solid state light emitters, at least some of the solid state light emitters being supported on the pedestal in an orientation such that principal directions of light emissions from respective emitters are radial outward from the pedestal through the bulb in a plurality of different radial directions, and at least one of the solid state emitters being supported on an end of the pedestal in such an orientation so that a principal direction of emission of light from the at least one solid state light emitter is substantially the same as or parallel with a longitudinal axis of the lamp; and

    a phosphor, remotely deployed in the lamp with respect to the solid state light emitters, the phosphor being of a type for converting at least some portion of light from the solid state light emitters from a first spectral characteristic to a second spectral characteristic, to produce an output of the lamp from the bulb that is at least substantially white.
