Kitchen LED ceiling light "exploded" during lightning storm
You experience a power surge in your house, probably caused by lighting.  Power surges can damage any circuits, but usually electronics like computers, TVs, or any electronic circuit boards in appliances and LED lights.
There are power surge protectors you can plug into outlets to protect TVs and computers.  There are also whole house power surge protectors that hook into your electric panel, they run about 150 to 200 dollars(think about 250pounds).
This is why it is recommended to unplug TVs and computers during lighting storms.
