Do not judge strictly, this is my first article in satire format on Habré.
If you are a real gadget addict and you already have a column lamp at home, wifi bulbs that turn on with a wild delay due to a large ping to Chinese servers, and you are still young and looking for adventure ...
Especially for you - I found a lamp that is definitely worth taking a look at.
The company that produces this lamp inspires confidence at first glance at the packaging.
* when I was looking for a star on a Christmas tree, I bought a New Year's lamp, when I came home, I found the inscription Ra> 90 (CRI> 90) on the box ... I certainly understand everything, but the design of the box is apparently drawn elsewhere.

GF-A67-7966A ( MT7966A)
The battery is 18650, but the weight is 28g, while the average weight of such a battery is ~ 45g.
Mains supply: on LED module 4.1V
Power supply from the battery on the LED module: 2.9V, then the voltage drops to 2.1 and the LEDs smoothly go out (as if the battery is discharged to zero (but it is not). There is no stabilization.
The maximum voltage on the battery after disconnecting the lamp is 3.8V. Charges up to 3.9V, maximum discharge (LEDs are almost off) ~ 3-2.9V.
Unfortunately, I bought only one lamp and disassembled it without arranging a "crash test", covering the lamp with a shade, but judging by the circuitry, the result is obvious, there are no temperature sensors on the battery. At best, it will stop charging.
