Abstract
By operating the filaments of high-efficiency tungsten lamps at higher voltages than normal, not only are the operating characteristics of the lamps improved, but a more desirable spectral energy distribution for color photography is attained, the increase of the blue-violet radiation amounting to about 140 per cent of the increase of the red-orange radiation. In view of the fixed voltages used on sets, the lamps are, in effect, designed for lower voltage and wattage. Data on the candle-power distribution with suitable reflectors are presented.
