Put a Metal Halide ballast in a room with no ventilation-see how long it lasts and then state that the longevity of the fixture is a lie.
Put a t-5 fixture/ballast in a similar situation-you won't be getting a year out of the unit,, so again, they must be lieing.
Put the most heat sensitive lighting option in a situation where it doesn't have a way of cooling down, and see how long it lasts-thus the longevity claims must be a lie.
Just like computer CPU's, LEDs produce massive heat, and require cooling. If cared for, they're going to last a long time-if not, they won't. So the claim of LED's lasting a long time is true, but the claim that all LED's are mounted in an appropriate situation isn't, this comes down to the manufacturer building fixtures correctly vs. using a claim about technology.
I'm currently designing and going to start working on an LED system that's going to be designed similarly to a water-cooled computer method, with each LED mounted to a water-filled heatsink, mounted to a gimble allowing me to rotate the LED's for specific highlighting/spotlighting purposes. Water will all be run through a radiator mounted outside the sump, on such a system I'd expect a very good life span on the LED's.
