Solar Lamp Opinions: Battery-Charged Motion Sensor Lights for Illuminating Dark Spaces

Hello.
I would like to ask about your opinions about solar lamps, i.e. lamps with a battery, which during the day are charged by means of a solar panel and are supposed to shine for several minutes by night at the sensor's detection.
Well, I would like to illuminate the square with such lamps, I note that at night without the light of the moon there is absolute darkness, a man of his own hand can not see in front of him. Well, I would like to ask if such lamps with a motion sensor have any meaning or if they shine too weakly. It would be nice if some kind of owner of such a lamp spoke up. I dug half the internet, but I did not find any sensible test, and I see at auction that the lamps are bought by quite a few people.

I dug up to 3, in my opinion, the best lamps
1.
2.
3.

specification according to sellers
1. a light source 120 LED SMD, a luminous flux of 400 lumens
2. LED SL310, luminous flux of 400 lumens
3. "80 super-bright, state-of-the-art LEDs", "THE BEST SET WHICH EVER TESTED ANYWHERE!"

What do you think about it? Does anyone have something like that?

400 lumens gives an ordinary bulb with a power of about 35W. There are LEDs that give about 100 lumens, in these lamps there are none, because they would give a pair of LEDs, not about 100. And specification 3 looks suspicious, lacking in detail - maybe the seller has never seen a really bright LED? And nobody writes, how long can it shine?

In the case of the first two they gave their lifespan
1. 1,000,000 hours, but it's probably a mistake, it should probably be 100,000
2. 50,000 hours

Generally, the first has the worst solar, the last 2x shorter cable and more than 2x more batteries (I do not know if it does not look good), I did not write about it, because I do not care about it, the lamps have to turn on, only for 2-3 minutes after motion detection, so rather a lot of electricity will not consume anyway. I mainly want to be clear that I do not have to put them too much.

As for the third, as far as the technical specifications are concerned, almost nothing has been written, no other vendor sells this model. Generally, I would like to order all 3 and then 2 to return.

It's not a lamp, it's a toy, buy something stronger It's December, the sun is almost gone. My lamps turn on at dusk. Batteries in this weather do not charge to the max, lighting time, or rather power consumption of about 6 hours, BMS turns them off because the battery is empty. I added a 100 W panel it's better charging current in the sun is 2.5 A in the shade 0.2 A is better the lamp shines until the morning The panel is mounted almost vertically the snow falls off it automatically

Hello, I am interested in this lamp, I will ask for its exact name and exactly what solar panel to add. Regards.

The lamps are available on Allegro, the more expensive you are, the better, i.e. they shine brighter and have a larger battery capacity. The prices of good lamps start from PLN 250 for PLN 50.
