Lamp using solid state source and doped semiconductor nanophosphor

A lamp, comprising:

• a solid state source;
• a bulb;
• at least one phosphor within the bulb positioned remotely from the solid state source;
• a lighting industry standard lamp base for providing electricity from a lamp socket;
• a housing supporting the bulb in a position to receive electromagnetic energy from the solid state source, the housing being mechanically connected to the lamp base;
• and
• circuitry connected to receive electricity from the lamp base, for driving the solid state source to emit the electromagnetic energy to excite the at least one phosphor remotely positioned within the bulb;
• wherein:
• (a) the visible light output from the lamp produced by excitation of the phosphor is at least substantially white;
• (b) the light output from the lamp produced by the excitation of the phosphor has a color rendering index (CRI) of 75 or higher;
• and
• (c) the light output from the lamp produced by the excitation of the phosphor has a color temperature in one of the following ranges:
• 2,725±145° Kelvin;
• 3,045±175° Kelvin;
• 3,465±245° Kelvin;
• 3,985±275° Kelvin.
