the designers of LED fairy lights are hardly likely to power the diodes to a level to get them hot, which would be likely to make them fail (safely) anyway.

I have a degree in Mechanical Engineering.  Are you familiar with the term "designed obselescence"?  If a manufacturer can gaurantee a way to make a product fail then they will, otherwise how will they sell you another one next year? other than pray you loose it.


I've had LED fairy lights that run hot and others that don't.  Ultra bright LEDS are designed to run hot, whilst far far more efficient than filament bulbs, LEDs stiill product heat as a bi-product of lighting up. Standard  red are the coolest, white and blue some of the worst.


But I doubt you could start a fire with one, you'd be doing well to melt a wire.
