Lamp hanging on gypsum acoustic panel

3.5 kg (~8 pounds) plus the weight of a junction box hanging on a suspended ceiling doesn't seem like a good idea. That's not to say that you can't anchor into whatever is above the drop ceiling. As ...

Is it possible to convert a pull-chain lamp to a "turn-knob"?

A photo would help. If you mean the pull-chain switch is part of the socket, then yes, you can easily replace that with a socket that has a twist switch. If the switch is mounted separately, then it's ...

How to open/unlock the BMA 2215 cable box for connecting a ceiling lamp?

I believe that the problem here, at least for me, is that it intuitively feels natural to try to press the round "buttons" inwards, to release. However, once you see one open (a catch 22, ...

Push-button light switch on/off reversed

There are several possible push-to-toggle electrical styles for a switch like that. You'll have to open up the lamp and have a look at the switch. If the switch has just two terminals then it is what ...

Can I just replace the LED controller of my lamp?

It's not designed to ever have the power to it switched off, same as most smart devices these days. You need to remove the switch, or replace with a remote switch designed to talk to the lamp, like ...

How do I wire my ceiling lamp?

The simple answer is: The same way the previous lamp was attached. But if you didn't have a lamp there before, or if you didn't take pictures, then anything is possible. The logical setup is: All ...

Lamp hanging on gypsum acoustic panel

You can not use that cable. It is not a power cable. It is a signal cable for the smoke alarm.

Disable motion sensor for a ceiling lamp

Is it just a motion sensor or motion+light? If it's just motion, you should just be able to put a tape on the sensor. Probably that tiny black circle.

lamp base fill material

You're likely correct that it's cement (of some sort) and it likely broke because the plastic got old and brittle, as it does, perhaps aided by an impact of some sort. I've seen sand used in lamp ...

Can a 4 wire dimmer lamp be installed with 3 wires?

The wiring diagram you show in the 3rd pic seems to show a lamp which has an 'extra' pair of wires for dimming control. This is unusual (although not unheard of) and would require a compatible (also ...

How would you secure a lamp socket in a wooden hole?

If you can find it, a socket like this is what I have used on a ceramic pot turned into a lamp. You can also get sockets that have a thread at the bottom (from another lamp)

Install pendant light without ground wire or grounding screw

These lights don't appear to be UL listed so I'd be thinking about not using them. That being said, you'll need to get a grounding screw from your home store, probably a 10-32 screw, and screw it into ...
