  • they do but you cant see it b/c the door is closed
  • Why would you want a light on in the fridge when the door is shut? Your food doesn't mind the darkness I promise.
  • Hmm... Although that's a sound idea the ultraviolet lights people use to kill airborne spores or bacteria are quite powerful (they'd give you a tan quite well). Now if you put that inside a refrigerator you'd infact be heating the inside of the fridge (and the food) and so the fridge would have to work harder to keep things cool. Now I wouldn't want to eat anything that's been exposed to UV radiation as it will be horrid on the outside and uncooked in the inside. Also the UV light is not 100% efficient so it will give off heat as well as the UV light this again heats up your refrigerator. The other reason that the UV might not work is it will only kill the surface bacteria on the food, it might still happily rot your food if it can breed a way inside the food. To Sum up if you did this to a refrigerator your food would suffer and become inedible and your fridge would use large amounts of power and would be really inefficient at cooling things. If you really want to keep food longer you should just use a freezer.
  • Well I do not think there would be any problems with this, the heat would not be much (heat is infra red not UV) and the effect upon food minimal (most food is in UC transluscent containers anyway, and dead stuff cannot tan). The real benefit would be in keeping mold and bacteria from growing in your refrigerator. In fact UV systems wrk well enough to destroy molds and bacteria in air handling systems and you can buy one sized for a home HVAC for a few hundred dollars. One adapted to run in a fridge, that would keep the thing clean (think no more spring cleaning), I would go for that. The bottom of the fridge is a great source for mold, may of which find fridge temps just peachy.
