During two sessions, the room was illuminated by fluorescent light and during two other sessions, by equal intensity incandescent light. Subjects spent significantly more time engaged in repetitive behavior under fluorescent light. Previous research suggested that these findings were related to the flickering nature of fluorescent ilumination.
Nov 21, 2019 the result of doe's action, if unchanged, will be the continued manufacture of energy-efficient halogen incandescent light bulbs past 2020.
Incandescent lamps, which also include halogens, produce a warm light, weighted towards the yellow/ red end of the visible spectrum. More energy efficient technologies than incandescent lamps, including compact fluorescent lamps (cfls) and light emitting diodes (leds), are available in a range of warm or cool coloured lighting.
