well, the light is only a very small one and is attached to a little switch. yes it is running on the same power supply but i agree, if one would to put a light directly to a power source then it would slow it down.
PS: sur i`ll post a pic of the inside but just not now becos it is 11.30 my time (GMT +1 i think)
edit: i have "updated" the front of the fridge so not so much breeze can escape through the clingfilm
