I've just had a "100W" LED bulb fail, after about 10000 to 12000 hours of use. Strictly speaking, it hasn't failed, but occasionally it will flicker very annoyingly, and I suspect it's only a matter of time before it fails, probably with me halfway down the stairs, so I'm preemptively replaced it.
It was a Tiwin 13W E27 super bright LED Bulb, which was supposedly popular in Germany, according to the Amazon webpage (I bought if from them, but they no longer seem to stock it).
I've replaced it with a Philips 100W warm LED bulb, bought from John Lewis for £7 compared to the £11 the other one cost me from Amazon. It's also definitely brighter than the older lamp was, although that may simply be that the ratings are lower.
The Tiwin claimed between 1200 and 1400 lumens for a 13W actual, 100W equivalent, whereas Philips claim 1521 lumens for their 13W actual 100W equivalent.
I'm not complaining too much about a 10000+ hour lifetime, although they claimed 25000 hours average lifetime, and it's way below that.
The same Philips bulb appears to be £6 from Amazon, so prices are clearly still dropping.
