lambayı açıp 3-5 saniye sonra kapatmak > lambanın açık vaziyette 3-5 dk kalması böyle bir şey var mıdır?

var tasarruflularda 15 dk az kapalı durcaksa hiç kapatmayın dendigini duymustum, o ısınma suresi vs. ama sarılarda tersi tabi

indüksiyon akımdan dolayı olabilir belki ama bu boyutlarda olacağını sanmıyorum.motorlarda açıp kapatmak enerji kaybına sebep olur ama bu boyutlarda imkansız gibi.

Myth: You save on energy bills by leaving lights on. Some people believe that the energy to turn on lights exceeds savings of turning lights off.
They talked to Mark Reisfelt, manager of the Independent Electric Supply where they purchased their light bulbs. He felt that it was best to turn the lights off.
To test the myth, they needed to measure energy usage during startup, maintenance (steady state), and shutdown.
For steady state energy consumption, they turned on several different types of bulbs for 60 minutes and measured their consumption using a Kill A Watt: * Incandescent 90 Wh * Compact Fluorescent (CFL): 10 Wh * Halogen: 70 Wh * Metal halide 60 Wh * LED: 1 Wh * Fluorescent: 10 Wh
For startup energy consumption, Grant hooked up an inductive current loop to a computer and measured the amount of energy used when the turned on the bulbs. With an inductive current loop, you run a wire through the center, which induces a current in the loop. This current is then measured by a digital sampling oscilloscope.
Based on the amount of energy consumed turning on the bulb, they were able calculated how long the bulb would have to be turned off in order to make it worth the energy savings, i.e. "It's best to turn off the bulb if you are leaving the room for":
Incandescent: 0.36 seconds
CFL: 0.015 seconds
Halogen: .51 seconds
LED: 1.28 seconds
Fluorescent: 23.3 seconds
In other words, its almost always best to turn the bulb off. Even the 23 seconds for the fluorescent lights isn't very long, and the rest of the times are pretty much blinks of an eye.
