Temu solar street light is surprising
🕑 Added 2024-04-29 01:23:48 +0000 UTCAside from the robust looking and decent output solar panel, this light has a chunky LiFePO4 cell and unusually minimised circuitry. It was quite fast to reverse engineer, since it seems to be a sensible design.

Amazon in the US has what appears to be the same thing but with a 30,000mAh battery (LOL) for 99USD (!!!)

It's a maximum of 5W spread over the full PCB, so the plastic may transmit enough of the heat out. The glass was glued at both ends, so may allow breathability of the inside. The main opening points downwards.

With a plastic case, does the LED circuit board overheat? And what about water ingress?
