I'm really disappointed with all the LED lights I tried (except one brand that doesn't exist anymore). Led lights were supposed to last 10 years at 8h per day. Initially they were expensive, but it was possible to get LEDs of good quality. 7 years ago when I was building my house I bought 100 gu10 7W 550 lumen cool white "halogen style" 240V led lights. In these 7 years I replaced around 16. Many of these lights are used 16+ h/day. I'm very happy with them. Unfortunately the brand dissappeared (it was a reseller brand).
Since then ever single LED I bought failed with a year or two. Big outdoor led floodlights 25W,50W and few 100W. Every single one fails in a couple of months. They're not even used that much as they have PIRs, maybe they are on 20min per day. Then there are E17 lights I bought for a small workshop (12 of them). None lasted over 6 months (used few hours per week in an unheated workshop). I'm not even buying the cheapest LEDs. It's the same regardless if I pay for "premium" or the cheapest.
I have so many broken LEDs I started fixing them. I have a hot air soldering station and a pcb heating tool. They always fail the same way. One of the LEDs is burned. Why? Because they are driven too hard that's why. If they were driven with 10% less power they would have a chance to last.
