    You are correct about everything but I feel I should point out that the amount of heat produced by an incandescent bulb in your fridge is miniscule compared to the heat energy of the warm air that enters your fridge as soon as you open the door. Cold air sinks due to its density and so when you open the door it all falls out and your fridge must work it’s ass off to cool all the new air back down to the set temperature. The heat added by an incandescent bulb for a few seconds is basically irrelevant.

    This is also why chest freezers are so tremendously efficient. When you open the lid, the cold air stays inside. Very little mixing occurs with the rest of the environment.

      Yeah, it’s not a lot of heat, but it starts making a bigger difference once you’ve got the fridge packed full of stuff (less air loss, also makes it take longer to find stuff, so the light stays on longer). I’ve had items at the back near the bulb get extra freezer burned because of the constant heating/cooling. That was quite an old fridge/freezer though, so not the most efficient to start with, and the temperature control could have been better.

      I do love chest freezers. They’re way more efficient and I find a lot easier to organize too. There’s some fridge/freezer combos that have a freezer drawer, but I’ve yet to find one that’s fully enclosed so all the cold air stays in. Most I’ve seen have wire baskets or something for the drawer… Having space for a separate chest freezer is not a luxury everyone has.
