Even then, where the hell did they get a 60W LED? LEDs with those kinds of power ratings are pretty hard to find, and they're going to be fairly expensive as well.
60W LED bulbs don't exist because the form factor does not allow them to dissipate heat fast enough to keep LED chips that produce >50 W in heat below 150 °C. Fixtures of 20-100+ watts are available as COB modules that get mounted into work light reflectors where the entire back side is the heatsink. Their driver is very simple, so they are cheap but flicker at double the mains frequency. You can mount one in a fridge with adhesive heatsink compound and unsafe wiring modifications, assuming it fits under the cover if the socket is removed. An alternative is a long low-voltage LED strip wound all around the fridge's interior several times.
Bulb gets too hot. Put it in refrigerator. Problem solved.
I mean, a 60W COB LED module mounted to the inside wall of a refrigerator will have a more than suffucient heatsink...
This a a 100w LED light, not a 100w equivalent. It's equivalent to a 1000w bulb. I bought a few to replace some old halogen shop lights.
Yes, I know... E27 1000W bulbs of similar size have indeed existed. However, unlike a $3 5x8 cm 50W mains COB LED module, you cannot mount one in the intended space in common fridges.
BTW, a little story regarding a 500W one: A Czechoslovak photographer needed one but like most heavy equipment in the Eastern bloc, they were never sold to individuals. He visited the factory for an alleged newspaper photoshoot and teamed up with my grandpa and other workers, who hung his desired bulb on his equipment backpack and pretended to sneakily follow him to the gatehouse. They laughed quietly, pointing at the bulb and thus socially engineering the doorman to enjoy the moment and forgo the usual pat-down. Officially, they just told anyone that the bulb had been a dud, which could not have been disproven.
My guess is that the fridge actually used a 20w bulb. A 20w LED is plenty bright.
