NEVER SEEN - PROTECTION TEST AGAINST ELECTRICAL SURGE in LAMPS 

Let's see if the varistor will protect the lamp, let's simulate a lightning strike, you can see how the socket turned completely black, put a 250 volt varistor with the lamp, protection test against electrical surges, to protect the lamp that is half lit, the LED lamp is blinking and lamps that stay on even when turned off. I used a microwave transformer for testing.
