Turn the Light Off

Once someone told me that he leaves the fluorescent kitchen light on all night even when not in the kitchen because it saves energy and money. According to him the startup of the fluorescent bulb is so high that it compensates for hours of being turned on. I was always curious about this but never found a good answer, until today: According to the article it is always better to turn the fluorescent light off, even if only leaving the room for 5 minutes. The startup peak energy consumption is so short that it does not compensate for leaving the light on. Here is the full article entitled "Does Turning Fluorescent Lights Off Use More Energy Than Leaving Them On?". In short always turn all lights off. This holds true for incandescents, flourescents and LEDs.
