A bulb is adapted to fit over and around a light-emitting diode emitting a light of a first hue in a generally Lambertian radiation pattern. The bulb has a generally spherical shape and a substantially circular external cross-sectional geometry, and further defines an inner cavity with a substantially circular cross-sectional geometry for housing the light-emitting diode. The bulb is composed of a light-transmitting material and a light color-converting material, with the light color-converting material converting the light of the first hue into a light of a desired hue, which is then viewed along an external surface of said bulb.
