Turning off the lights
So, I have found myself wondering about how much power lights use when you initially turn them on vs. just leaving them on. I kind of remember being told at some point that if you're going to turn the light on again right away, there's no point to turning it off. You're going to use more power to turn it back on than by just leaving it on. Well, guess what!
IT'S NOT TRUE!!!
According to Trust Power, the burst of power being used when you turn the light on lasts .4 seconds. So, unless you stand there and just flip the switch constantly, trying to achieve an all-strobe environment, you're not going to use more power when you turn the light on and off.
This is good. My typical morning - leave bathroom after shower, turn off light. Realize I forgot my contact lenses, turn light back on. Turn light off. Realize I left my cell phone on the counter when I got my contacts. Turn light on and off again. Go back to getting ready. Realize I never brushed or combed my hair after shower. On. Off. Am I wearing deoderant? On. Off.
I feel better knowing I am only wasting time, and not energy. Of course, now that I wrote it all out, I realize just how much time I'm really wasting...oh, well. At least I don't have to get dressed in the dark.
