I must be doing something wrong, I can't remember having any 120V LED bulbs fail. CFL, yes, but no failures of LED yet. I"m glad to see CFL fade away.
Ha, ha. Yes yellow glasses great for helicopters. Please let me know what you think when you get them. They made night driving much less stressful for me. Let us know if you notice any benefits or disadvantages.
You're lucky. Or maybe I am just very unlucky. Although I was an early adopter of LED, so perhaps I ended up with a bunch of the early versions that had more issues?
Also, one brand in particular has been very bad for me - Luminus brand from Costco. Terrible reliability. I will never waste my money on those again.
When I recently had to replace about 4 LED bulbs in my house, I went with Philips. Fingers crossed.

Like I've said, I've had Philips for years now, and not one failure of that brand.
The oldest one I have, a 15W equiv. (draws 3W actually) for nightlight use in a small lamp in the dining room, has been burning constantly for over ten years now.

Ironically, I have had failures with the relatively expensive Ikea, GE and Cree LEDs but I attribute that to the old PWM design. They begin to cut out when they get too hot so it depends where you use them. If you see a lamp with a heat sink collar then it either a super bright (> 150W equivalent) or it is an old design. CFLs were and now LEDs are subsidized by the city power here so "Sunbeam" (Chinese) LEDs are super cheap at the dollar store, and I have never had any fail. The city replaced all the traffic lights a few years ago and some were too bright, but I think they had fixed that now.

All my original Cree LED bulbs (from whenever they first sold them) are still good, and are 5000K types.
One thing I like about the LED vs the CFL is the almost instant on of the LED. CFLs could be slow, and some took a couple of minutes to get up to full brightness. I remember them in stair wells and in bathrooms at work. Really bad places for a light that needs to be on NOW and is only on for a few minutes at a time. LED is much better at that.

Fancy fancy....even GPS controlled.
I can imagine the replacement cost if they fail, or need replacment from an accident.
I’ve had screw-in LED bulb replacements that have been in continuous service for 10 years. Every “LED fixture” that uses a bunch of surface-mount LED chips permanently installed in it that was ever put in this house has failed and been thrown out. And replaced by screw-in type bulb replacements.
That is very imprecise as it depends on brands of both etc. Normally fixtures with A brand LEDs, A brand PSU and enough surface for adequate cooling outlast the bulb types. I have quite good experiences with large numbers of Phiips and Osram fixtures and these are simply good. Some even have several sections of LEDs and keep giving light when one section fails. Light output wins hands down compared to bulb types. I did obtain a lot of no brand fixtures (11W, warm white, 4 Euro each) just because of the low price and of this lot of 20 only one of them has failed in 2 years. Unexpected low failure rate for low price stuff.
The way you put it the bulb socket is the cause for a longer service life, regardless of the brand and quality 🙂 Using bulb types is simply convenience.

I started using LED lighting in my paint booth long enough ago I hade to build my own panel out of 100 discrete T package units. To limit the current I used series capacitors into diode bridges to feed multiple strings. The whole thing ran off my low voltage 24VAC line previously just used for control circuits. That was upgraded years ago to higher power units on a heatsink.
Currently it is off the shelf PAR style ones.
My first units at home I made from a 1,000 unit reel that I got surplus. I use a plastic tube to hold the chips. A single resistor is the current limiter. They run off my home 24VAC supply. The entire basement is illuminated with these tubes and with so many individual sources, basically one per square foot, the level is not just bright and uniform, there are also no shadows.
I did buy two sets of Osram I believe high power chips to make grow lights.
At home all lighting is LED and the energy usage is almost unmeasurable. (9 other fixtures.)
At my shop we replaced low bay HID fixtures with commercial LED lamps using an adapter to replace each old fixture with 5 LED bulbs. Not surprisingly the cheapies failed quickly and the more expensive units run just fine. The savings in electricity have given a three year payback. The other advantage is no start or restart time, thus allowing turning off the lights when not immediately needed. Also a bit brighter having about doubled the lumens rating and the HID lamps would dim significantly with age.

Try cutting or taking the lens off and you will find many wasted lumens. Warning do not stick your fingers in while it is live or if children around.
I have some feit brand 13w spots that have the outer weather protection and then inside that they have another lens for each led source. My cuttings and seedlings love them.
For the bigger stuff it is still the T5-HO, the cost per lumen and depreciation is hard to beat imo

I replaced every lightbulb in my house with Wiz full color LEDs. Probably opened a cyberattack vector but they are much more useful than you might expect. And I'm not important enough to cyberattack.
Context: I live in a region with clouds and dark winters. The lights have an automated feature that adjust spectrum over the course of the day. Bright white in the morning to yellowish at night. They can turn on during a schedule. The other morning they turned on but when I woke up I thought it was sunny outside. Nope, a cloudy dark day in reality. I don't turn on the light in my bedroom. I turn on the light outside the bedroom and the rest of the house. It feels like sunlight is coming into that room through the windows. It's a really neat sensation compared to flipping lights on by hand, which I'd rarely do. In my mind I think it's morning so I don't flip on lights. I suffer through the dark. But the automation fixes that psychological blip.

Yeah you have to marvell in the fact that society has progressed to the point that the lamp ( not bulb, as hammered into to me by the vet Philips lighting Eng) now has an IP address and a web interface 🙂
But it still is referred to as the ole lightbulb 🙂 funny enjoy, your RGB lightbulb.
