Hello, i made circuit for turning LED reflectors with FET (IRL540). I connected 4 LED reflectors with 40W of common power consumption. Power supply is a little bit more than 12V. First circuit worked without problems for a while but after about an hour FET was totaly burned. Now i am wondering why…

Burned FET

Turning LED reflectors.
Is that with a motor?
