While I'm spouting crazy ideas...
Why don't they sell LED replacements for refrigerator lights? Think of it, your fridge and freezer are the last place you want a conventional, hot tungsten lightbulb. They are also a pain to replace. Put in an LED replacement and never worry about it again. Cool illumination that lasts some 100,000 hours. White LEDs or a blend of colors for a natural hue, maybe Red so the light doesn't hurt your night vision during midnight snack raids, or Green to give the food a ghastly glow and help keep the diet going. Surely the The LED Light guys have the answer somewhere?
