It may be that the LED is being powered with 60 Hz AC. This makes it OFF half the time and ON the other half, creating a pronounced flicker.

This is far more pronounced than the flicker of florescents Since they are not OFF for half of the time. They only get dimmer, briefly, between AC polarity transitions.
