If I have to get up from my desk to go get somthing, would it cost less to leave my light on only for a few seconds until I get back, or to turn it off and turn it back on when I get back?

Let me tell you this. Incandescent light bulbs have a life expectancy that is shortened by turning them on and off.
Lights that are left on will last longer (more hours) then those turned on and off.

It will cost more to turn the light off then back on...
this also works for your gas tank...
drive on the expressway as much as you can...
less lights...less starting and stopping...

It probably wouldn't make any difference.
