New Lights Dying Quickly

I moved into an older building, and the old fluorescent lights were dying (like the ballast, not the tube). Rather than deal with that, I replaced with a new fixture and LED lights.

Great, problem solved.

Except the LED's are failing in like 6 months. This is my first time living on my own and dealing with changing lightbulbs, but I'm pretty sure they never burnt out that quickly in other places I've lived.

Should I be concerned? Is this some sort of miswiring in the light fixture? Or have I just never noticed how often they needed changed before?
