    The CIE positions D65 as the standard daylight illuminant: [D65] is intended to represent average daylight and has a correlated colour temperature of approximately 6500 K. CIE standard illuminant D65 should be used in all colorimetric calculations requiring representative daylight, unless there are specific reasons for using a different illuminant.

    Because glow discharge occurs readily at 110-120 volts AC, one could use these bulbs in standard household lamps in the United States. The phosphors used in the bulbs were somewhat brittle, necessitating care in handling. Shaking or jarring the bulbs would cause flaking and migration of the phosphors to other parts of the metallic sculpture.
