The boss fights in a Raid Finder raid are simplified and nerfed relative to the normal difficulty. Often the bosses have less health. Usually the damage done by various boss abilities is reduced. Specific mechanics where a single incompetent or lagged person can wipe the raid are usually removed.
An LFR run is a gentle introduction to the bosses, and can be educational for a player who is still learning the fight. However when you transition to normal bosses, expect to get your butt kicked while you adjust to the un-nerfed damage and mechanics.
