But you can see better to organize the shelves!

I don't know how it is in other countries, but here in the UK we still have light sockets rated for the older incandescent bulbs that needed around 60W. But LEDs are much more efficient. Sometimes you see LED bulbs with absurd things like '5W = 60W' written on them, meaning that it actually uses 5W, but it's as bright as an old 60W bulb. You basically don't need to worry about the safety limit of the socket, since the LEDs are way under it. Of course since the socket is rated for 60W you could plug in a 60W LED, which would be as bright as an 720W incandescent bulb.

Which I suspect is what this person did to their poor fridge.
