A ton of LEDs flicker at 120hz which makes me crazy. It's like a strobe effect that I only see when moving.

The Edison style are often like that. They use four led elements configured as a full wave bridge rectifier but because the diodes are themelves the load ther is no place to put the lowpass and so you get 120.

Oops I wrote 60Hz but meant 120Hz.
