I changed the LED lamp, and it shines when the power is off

Recently replaced the LED light bulb in the chandelier. The old lamp started blinking after three years of operation.

Such a 16W LED lamp was purchased. Cold white light. Shines without flicker. But the fact is that when you turn off the chandelier, this new lamp continues to shine, but with minimal glow. The former, which remains, goes out completely.

A chandelier in an apartment building.

The smartphone camera has high sensitivity and transmits the frame as if the lamp was shining at full intensity. But the lamp shines at 10-15% incandescence, like a night light. I thought it was some kind of short circuit in the cartridge. Swapped lamps. The new lamp behaves in the same way in the other socket.

The thoughts were: zero breaks in the switch, and the phase remains on the lamp. And the current finds some kind of microconductor (a leak somewhere in the wiring). And this current is enough for the lamp to glow.

The second explanation: the capacitor in the lamp accumulates charge and slowly releases it, causing the lamp to glow. But when I came into the room in the morning and looked at the chandelier - the lamp continued to glow in the same mode of 10% incandescence:

The night lamp was shining in the morning. The capacitor charge would not have been enough for the whole night. Those. the version with a capacitor charge was not confirmed. So, the current leakage and this leakage is enough to light the lamp at 1/10 incandescence?

Gif-animation with video how it looks. I screwed in another lamp of this brand (three such lamps were purchased). The effect is the same for everyone.

The version with current leakage in the chandelier is also not confirmed, because screwing this lamp into a socket in another place of the apartment - the effect manifested itself the same:

The lamp here, too, after turning off the electricity turned into a night lamp. What's with this lamp? The instructions for it do not say anything about such an effect. Obviously, a small current is enough for her to shine. But where does this current come from - the circuit is open! Maybe everything is trite and simple, but I'm not an electrician with a lot of practice. Write in the comments who knows.
