AC electrical devices often adjust their current draw, based on the voltage. As the voltage drops, the current goes up. This increases the current load, as well as producing more heat. Devices often flicker rapidly between just on, and off. The LEDs were experiencing that.

DC is even worse. Microcontrollers REALLY do not like being browned out. I've seen it smoke components, as well as easily corrupting stored data.
