Which reminds me, I have a bulb that has been burned out in my fridge for over a year. good thing there's two.
When the final one goes, they carry appliance bulbs at Dollar Tree. You may have to replace them a little more frequently, but you can buy 4 for what the appliance shop/hardware store wants for them.
I like LED traffic lights, but they seem to fail quite often around here; patches of black or flickering. It's a moderate climate, so perhaps they are just being made poorly?
I can't wait for a practical solution for household LEDs; the household lamps you can buy with a hundred or so LEDs are way too expensive. The "real" white ones that have a combo of white and yellow LEDs to produce more "natural" light don't seem to blend together very well; some sort of fancy reflector/diffuser is in order. LEDs would solve the dimming problem that CFLs suffer from.
