Product review (5 stars): This is the only thing you should use in a fridge
I had never considered the absurdity of using a super-hot incandescent bulb in a space that is supposed to be really cold.  That has been made clear to me now that I have this LED bulb side-by-side with my old bulb in my fridge.  The LED emits a cool blue-ish light that seems appropriate for a fridge.  It's also really bright.  Most importantly, there is no detectable heat.  If I move my hand 4 inches to the left, the heat off the old regular bulb feels like it's about to cook my hand in comparison.  I'm going to get one more of these so I can be all-LED inside the fridge.
