Abstract
An electric lamp includes a first light source and a second light source and power circuitry configured to selectively energize the first light source and the second light source. The first light source is configured to produce light that is substantially free of wavelengths below about 530 nanometers, and the second light source is configured to product light having wavelengths of less than about 530 nanometers. The electric lamp is configured to produce white or near-white light in a variety of color temperatures, while retaining good color rendering index.
