Gauss 8w cordless lamp or unexploded ordnance

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.
