Most lights emit a range of frequencies. Kelvin temperature does not refer to the nanometer wave spectrum emitted from the light emits but the over all color of the light. Most common household incandescent emit a low kelvin temperature in the 2,700-4,000 range. Which, IMO anyway, looks terrible over an aquarium since its a ugly yellow light.
