Im a LED lighting engineer. That's likely cheap solder paste and/or poor thermal profile during reflow. If you do want to rework one, thats fine (assuming you have an adequate experience level, do not try at home, etc etc) Just make sure to desolder the connector first and then you can put it on a hot plate. The LED bulbs sold to the public are the cheapest POS ive ever evaluated. Around 5yrs ago, all suppliers shifted to overheating their blubs on purpose to insure planned obsolescence.

LED Lightbulbs, the pinnacle of "planned obsolescence".
when they first came out, these things should've lasted forever and be much more cost effective.
but we can't have nice things in this consumerist market.

If you cut that 24Ω resistor off. It will dim the leds slightly. But make it much cooler & work for years.

Why is it not safe? The top pcb doesn’t even affect the power supply below it

i fixed and re-used tens of led bulbs throughout the years - though they become less and less "fixable" (the hassle went up exponentially to the cost of a new one)
the bulb doesn't become less "safe" unless it was originally unsafe. (Chinese low quality unstable plastics, not self extinguishing etc..)
especially with the new "driverless" bulbs such as this - the entire circuit is built like a string of fuses, as long as the plastic is up to standard - the most catastrophic failure will be barely noticeable.

It was completely safe, dude

The "13 year" LEDs that last 13 months. That being said, a lot of LEDs aren't supposed to be in a fixture that's fully enclosed. There are those that are marked as "safe for enclosed fixtures".

That's real feckin safe to use man. You should see the shit we do here to reuse and upcycle our lighting.

So you fixed it and throwed it into the recycle box? Here in Mexico we expect it to work for 10 years more after we fix it.

LED peaked in 2017
early on, they were all crap while factories worked the kinks out, then there's a golden age of being better so everyone gets them, making old bulbs obsolete
We have now reached the end-stages of light bulb production, where they figure out how to make everything as cheap as possible, and make it so we have to buy more of them
Welcome to the age of Enshittification
(it's a shame you threw that out, it's safe, and would last a LOT longer then modern 'frosted glass' LEDs, some of which don't even use PCBs anymore, just bent wire and those weird LED filaments)
(Count the filaments in new bulbs btw, if there's fewer than the rated wattage, it'll last 6 months thru 2 years before burning out from overheat)
(Basic rule of thumb, the heavier the bulb, the longer it'll last)

I’m fixing them regularly.

COBs literally outlast the solder. what amazing tech

replace with 50-yr bulbs from the Emirates 😂

Я работаю на профессиональном производстве и меняю такие же только большие каждую неделю... Производители решили захлебнуться в своей жадности

Remerber folks. These were sold as environmental friendly. But ONLY of they run for 10 years.. they'd often blow after 3 years for me. Imagine all the ewaste cuz 1 component fails. This stuff was never environmental friendly unless it's built right and is easier to swap components

For a more effective reflow dab flux on all the solder joints. It will make the process almost automatic. Also not sure if that's what happened here but be sure to let boards cool down before pouring a liquid cleaner on them, if you see or hear boiling that's a huge thermal shock for those parts.

Like everything else - there's the good stuff and the cheap stuff. LEDs advertise 50,000 hour life. I haven't seen one last anything like that. Since people usually buy the cheapest one they can find and think it's going to be as good as the most expensive one is why manufacturers make cheap stuff. Usually turns out to be more expensive than the good ones.

That is what I refer to as cheap Chinese LED breakdown..

Huh that's interesting. I wonder if the heat from the driver chip caused some already weak joints to loosen. These bulbs are often engineered to work with the least number of components required which means things will operate at close to their maximum ratings. The board looks surprisingly similar to the ones I've taken apart, but I've never seen any cracked joints on the ones I have. Some of mine have failed with the driver chip failing and overcurrenting the LEDs.

It's actually a lot safer now that it's fixed and properly soldered.
