Already out of habit, I run into mn "Traffic Light", to see what interesting things they brought for inexpensively. This time I drew attention to table lamps, quite inexpensive, with a beautiful design. No kidding, I really liked it. But as with people, sometimes the wrapper is beautiful, but inside it is not at all what you expect, or what should be. But let's start in order ...
Scrolling through the gallery:
The luminaire is very convenient to fold and unfold, has articulated joints, a touch switch, is powered by 5 volts, like a conventional charger. And most importantly, it is LED and consumes very little power... very little.
If you have scrolled through the gallery to the end, you probably noticed what is written in the instructions. Namely, we are interested in the power of the lamp. The declared power is 5 watts. But they got excited, overestimating it many times.
By the way, I forgot to mention, the lamp has three modes "dim", "normal" "bright". And in all these modes, I checked the power consumption with a wattmeter. And also measured the brightness of the glow in the "suites" using the application. Let's see what happened, read the captions to the photographs.
By the way, until I forgot, I bought a 60 W LED lamp in the garage. shines very brightly. The first two photos. If you need a review on it, let me know through the Comments. I will also gut it, measure the power and luminous flux.
As we can see, there is no five watts of power in this lamp. They cheated again, as with a vacuum cleaner (link to the investigation below). What to do? Can be taken back to the store. But I decided to modify it, remove unnecessary things. To shine brighter. To do this, remove the plastic.
These LEDs should remain without a protective glass, which took away half of the luminous flux, according to repeated measurements. For those who are afraid of open diodes, have 5 volts injected should not hit you. Charging from your phone doesn't shock you, does it?
For those who are interested, I disassembled the lower part, leaf through the photos.
Inside the case, the platform, there is an electronics unit, a sensor copper plate that reacts not only to touch, but also to weak blows to the lamp. The electronics unit has a circuit for switching on the lamp in different modes, a power socket and a red LED. By the way, this scheme can be used in homemade products ...
I ended up with a weak lamp that shouldn't be bought. This is not a lamp. This is a NIGHT LIGHT.

I hope the information was useful and deserves a like!
