The light fixture in my apartment started flickering and not turning on all the way, and it was only a few years old (On a dimmer switch, the dimmer-compatible driver in the fixture died). I couldn’t even fix it myself because it’s hardwired and my landlord wouldn’t be happy with me playing electrician. So I was stuck with no light in that room for weeks until the landlord got it replaced.

Not to mention I couldn’t change the color temperature to match the rest of my lights, which drove me nuts.
