As someone who lived with them for the first thirty years or so of my life I am very glad they are gone. I haven't had to replace a single light in my last ten years since I moved to a home that is all LED while it was a constant thing in my childhood.
I need to replace LED bulbs/reflectors 2-3 times a year.
Osram, the best for it's price range, but they are running too hot.
Really? I don't remember the last time I replaced an LED bulb. I replaced one old CFL with an LED when it died last year, but before that... I genuinely can't remember an LED bulb dying. And I buy the cheap ones. Are yours being overheated? Maybe you have really bad power quality?
Not the same guy, but I have some LED bulbs I've never replaced. I have some where I need to replace them every couple years or so. It's... weird. I think it's gotta be certain types of bulbs and/or the wiring in those parts of my house that just die faster.
I'm betting on bad airflow on some fixtures, installed by a landlord.
And/or bad switches? Legrand branded.
Some bulbs have cracked plastic housing.
They are rated 220-240 V AC, 50/60 Hz, I think have constant current regulator.
I have one specific light fixture that kills led lamps with no mercy. They don't fully die though, just decrease luminosity over time till they are useless. Tried with brand and non brand lamps. I think because it's basically upside down glass cups with no vents at the top.
Yeah, if they're trapping heat, that might be causing overheating. If you care enough, you could replace that one with something with vents.
It's more likely that my wife replaces my face if I touch that
I've been using GE Relax HD most recently. I don't remember when I bought them, but it has been at least 5 years. I haven't had one die yet.
(All the Cree bulbs I used before these died quickly.)
Edit: I have read that LED bulbs usually die early because of their driver circuitry running too hot. If you are able to give yours better ventilation, it might help.
Might have power spikes in your wiring? Some household aplliances are really bad for that.
I don't have an instrument to measure it. But good clue.
