Can I replace the base weight on a floor lamp?

@dadibrokeit @rickm15860 plaster of paris does not have enough weight. Ask me how I know that. Yes, fixed on of those torchiere lights with a broken base. Knock the old stuff out as much as you can. No reason to go all wild on it, just tap the loose stuff so it falls out. If all of it comes out, good. If not, good too.

Go to your local building supply store and get yourself some concrete repair mortar. Disassemble the light as much as you can, and turn it upside down. Take a look a the current base and see how the power cable is routed through that. The same goes for the center post mount. See how it is currently sitting in the base. It will help to see what this all looks like, so go ahead and post a few pictures of the base with your question.

Once you figured out how to route all of this, use some sort of material (cardboard, wood etc and create a form that goes with your base. Mix the mortar as instructed on the package and pour it in the base. Use a piece of wooden board to scrape the top so that it is level with the metal base. Again, we can explain this better when we see your base.

Not a complicated repair, just a bit of a PITA depending on what the current one looks like. Also, make sure that you do not spend more on material then a replacement light would cost :-)

@rickm15860 perfect!

No matter if you remove all of the old "concrete or just part of it. You need to protect the center as well as the cable run. Get an old round glass or even a plastic container with roughly the same diameter as the center of your lamp (just higher than the base). For the cable, run a piece of wooden board, not sure where you are but something like a piece of 1x4 would work. Place that from the round container to where the cable exits the base. Cut that the length of the cable run and again it has to be higher than the base. Now you could "pour" the concrete in there.

In your case I would remove the light itself since it looks like a rather tall lamp and not removing it would be pretty cumbersome, Not impossible of course. Also, it appears as if the current concrete extends slightly past the base. You could consider p;acing har dard cardboard ring on the inside of diameter of the base with just as much overhang as you current base. If you want to place something on the outside diameter of the base it has to be rigid since it may "fold over" otherwise. That would/could make your base wobbly.

I do hope that this makes sense since I can visualize it but not sure if my vision makes sense to you :-) Once you have it formed out, place another picture of what you have and before you pour the concrete. Then we can all double check for any issues that we may have overlooked up to that point.
