LED light bulbs are shit because of intellectual property. The LED array, the heatsinking configuration etc. are all so heavily patented you can no longer make a decent LED bulb without patent infringement litigation. So many lawsuits, with the norm being to sue the retailers as well.

Seoul Semi, Cree, Epistar, Nichia, Feit, GE, Philips etc. they all are constantly suing each other and the retailers over their LED bulb IP.
It's sad that LED bulbs are still struggling to outlast incandescent bulbs.
Cree LED bulbs were terrible, not that Cree has ever been a profitable company but their bulbs barely lasted a year and LEDs failing, just pushed too hard.
Next I tried Philips bulbs- which are total shit, the PCB and electrolytic capacitor inside badly cooked due to high heat, open-circuit LEDs. But the LED's are the best I've seen for CRI. The change to COB also makes the spot lights narrow. I can't get them to last more than about 3,600hrs. You would puke if I showed pics of the failed boards.
Next, I tried Ikea bulbs and they are working great, many at the 7,000hrs point and still working fine. But only warm white is offered.
