Each pixel has 3 LEDs, with a maximum current of 20mA each. Since the drive method is just resistive, the power loss to the enclosure is pretty much 3. That looks like an off-brand Apple charger, which is probably not particularly efficient, so expect a few more watts to dissipate from that. At this point, the TDP is similar to if not larger than a Philips or other commercial smart bulb with fewer lumens, mind you.

And even then, the case temps in an upside down lampshade like the one in the github repo can readily reach 60C I have measured this on one of my bulbs. Unfortunately, that charger may also just outright go on fire regardless of the state of the rest of the circuitry. Anyway, I spent quite some time designing a plain old LED bulb that would fit in an A socket some years ago. IMO most of the work is thermal design, not electronics design. The advantage is most of the thermal and optical diffuser design, which is hard, is already done for you.
Your confidence may mislead someone into assuming you are informed. PCB tracks can overheat, tracks can point off the substrate and short.

Thin copper can melt. UL-Listing in the USA serves as a near guarantee that the device will fail in very specific ways such that it disables itself i. If it were to reach higher temperatures it might exhibit nastier behaviours, but for several hundred degrees it will gently melt with a bit of charring ratehr than igniting.
ABS on the othr hand could be very nasty, it burns quite easily and gives off some pretty horrific gasses in the process.
Besides, if the adapter and the charger are approved, there is nothing illegal or should be nothing dangerous here electricitywise. Say you have 10, GPU chips all the same produced.

Binning means separating these chips and categorizing them based on performance. I assume the terms originates from separating these chips into different bins.
Maybe suggesting that the project creator should have individually tested each led?! So manufacturers test them and group into categories physical bins depending how well they worked. The best ones go the big players willing to pay the money, the barely functioning ones go to some little guy on aliexpress who then resells them for what looks like a steal. For example none of those small cube chargers are rated for devices larger than a small USB device or tablet.
