Why are lights put in fridges? do we need them? With the interior being white do they actually help you see what is in back. I suppose if the fridge is in a really dark pantry type cupboard it might help but otherwise🤷 I did have a fridge that had a bleep if you left the door open too long now that was helpful.
Lights are not on in fridges 24/7. They come on when the door is open and turn off when the door is closed.
If I leave the door open too long both my fridge and my separate freezer sound an alarm, but that is to stop the cold air leaking. The light turns off as soon as I shut the door. The light is a very low power LED light and the light uses less than _£1 a year Not enough to worry about.
And yes I do find it helps to have a fridge light. My fridge and freezer have their backs to the windows so get no direct light in them.
Freezer and fridge doors are not often on for very long for
