Because quality LED fixtures are designed for 50,000+ hrs in most cases (5.7yrs continuous), I expect they have a better warranty then a bulb alone, and they are optimized optically, electrically and physically for an LED application, would be my viewpoint. Both versions still have the same components cost wise for LED applications, the only difference is the housing/packaging, mounting.
Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
