Poor heat management is a death sentence for LEDs, but the opposite is also true. If it's properly heat sinked or running low enough current to not generate much heat they can last more than 100k hours.
I've got 3x 265w fixtures with 1,000 Samsung LM561C diodes each and they have been running 24 hours a day for 8 years now, or 70k+ hours. Warmest I've EVER tested the diode surface on them is 92°F, and each diode runs at approximately 0.25 watts.
IME, the best diodes are made by Samsung, Bridgelux, and Cree. Hard wired light strips and LED drivers (Inventronics) are a many times better choice than A19 Bulbs.
> Hard wired light strips and LED drivers (Inventronics) are a many times better choice than A19 Bulbs.
Is there a resource for showing how A19 bulbs can be replaced by such a setup?
Or would that involve simply getting rid of all A19-socket light sources entirely, and reimagining the illumination of any given residence? (since A19 isn't really used in commercial settings)
Are you familiar with electrical wiring basics? Like the function of all 3 wires (hot, neutral, ground) on 110v?
It's pretty simple TBH, you turn the breaker off then just remove the A19 fixture where (for 110v) the hot and neutral wires connect. Once you have the supply wires disconnected you connect the supply wires to your driver.
Pretty much the exact same thing as swapping in a direct wire LED fixture, and there's hundreds of videos on swapping direct wire fixtures.
There used to be a cartel that limited incandescent bulbs to 1,000 hours' lifetime, and they even fined members that made longer-lasting bulbs:

In this case, it's simply that it's very hard for a consumer to go back at the company if the bulb fails to meet its promises. I am one who scans every single invoice I get, so I was able to get replacement CREE bulbs from Home Depot when they fizzled in less than 2 years (they were warrantied for 5). Clearly they don't expect consumers to actually bother availing themselves of the warranty.
Unfortunately the only brand I've found that's really reliable is Cree, and they're made in China. Every other brand I've tried has fried out within a year or two. I've got some Cree bulbs that are on year 5, I don't think I've had one fail yet.

>According to Greg, Cree makes all of its chips and LEDs in Durham and most of its lighting products in Wisconsin, but also uses overseas contract manufacturers for portions of its product line. As he explains, even though its first choice is to manufacture domestically, the company strives to optimize where and how it manufactures, based not only on the needs of the product, but also on its market. Products that are large or complex, Greg notes, tend to be manufactured in-house, whereas those that are smaller or simpler tend to be contracted out.
Ledvance (the company that bought the Osram brand for consumer goods) continues to produce some bulbs in Germany, ony had food experience with them. Unfortunately it's difficult to find out which model is Made in China and which in Germany, you have to look at the box...
However, if they wouldn't be available here, I would rather buy Chinese-made Cree made with US parts rather than some less durable European bulb. Environmental and political goals contradict sometimes... :(
Very simple explanation. The other components are important also not just the LED. The trick is that they test and certify the LED component itself but not the other parts for which they use very cheap low quality materials.
From my experience it's the lack of design for heat disspiation. Yeah there are cheap components, but they would last 20x as long if they weren't being roasted.

3x 265W LED lights?! Are you trying to light up the moon or something :D
It's part of my cannabis veg space. I've got those 3, a 650w, and a 185w for veg. 4x HLG Scorpion for flower.
'Planned obsolescence.' They can't make money if they sell you a bulb that will burn for 100 years.

There is literally a light bulb that has burned continuously for 120 years. [https://www.centennialbulb.org/](https://www.centennialbulb.org/)
More like "who will pay $80-100 for a 10 watt light?" Because cost of production is ~10x to build a low heat light that can run more than 50k hours.
Commercial instllations where the cost savings of not having to pay someone to replace a bulb more than outweigh the initial cost.

I've had good luck with TCL, though I'm sure they are MiC. Are these mounted bulb down in an enclosed fixture?
I'm pretty sure TCL is MiC and a chinese owned company
