If anything, an LED should always be turned off, even if you plan to return within 15 seconds. It has zero "start up" current, and switching has no effect on an LED's lifespan. However, an array of high powered LEDs will use a significant amount of power and should be shut off when not in use. This will greatly increase the LED's lifespan as its working hours and heat dissipation are reduced. | |

The amount of electricity consumed to supply the inrush current is equal to a few seconds or less of normal light operation.... Therefore, the real issue is the value of the electricity saved by turning the light off relative to the cost of changing a lightbulb. | |
