ABSTRACT:
A lamp for emitting in the visible portion of the spectrum, which utilizes a fill which includes a selenium and/or a sulfur containing substance. The lamp has superior performance characteristics, including long lifetime and excellent color rendition. The bulb may be either electrodeless or electroded, and may contain additives for emphasizing a desired spectral region.
