bought some LED christmas tree lights this year and paid a lot more for them than the normal filament bulbs. The filaments magically always fail to come on the following year despite working fine the previous christmas. How do they manage that? [ incidentally a japanese engineer told me they are now making stuff to fail very soon after the one years warranty is up. Also did you know the British county courts are sympathetic to claims that many especially expensive items should last for more than one year].
What i am asking here is whether it's possibly true what the shop assistant told me; that, 1. LED bulbs will last practically forever and, 2. if one bulb fails the rest will continue to light?
Would any of you really clever people possibly be able to explain simply how an LED is different from a filament bulb? thanks.
