Exclamation Can I use a 50 watt bulb in a 20 watt desk lamp?

I have a little Ikea desk lamp. the bulb burned out and when I was at the store I forgot what bulb to get so I got a 50 watt one. when i got home I saw it says "max 20 watt". What would happen if I overlamp and use this 50 watt? Like, is there actually a risk of fire or melting with a bulb this tiny or is it just a legal precaution?

Yes, there is definitely chance of the lamp overheating to the point of catching fire. Fifty in a lamp rated for twenty is two and one-half times the recommended wattage.

Watts directly equals heat in an incandescent light. Over lamping could damage the fixture and/or make it so hot that you be severely burned from an accidental touch of the top part.

The transformer is probably rated for a maximum of 20W, too.
