Black Outdoor LED Hanging Light

The height of the fixture is 91/2 inches with an additional 2 5/8 inches with the cap and loop at the top of the fixture for a total of 12 1/8 inches. The diameter is 7 inches. Caution: I suggest to not install the glass shade until you have completed the hanging of the fixture. And when you do install the shade make sure it is tightened firmly as the thread is a loose fit.

Bottom is open and it casts a perfect circle pattern on my porch floor. I'm 100% happy with this fixture.

There are multiple LED chips in all of these lamps. Usually those chips don't all go out at the same time. One will go, then the next, then the next, etc, etc. Others will likely continue to work for a while. There's probably no way to replace them, so the answer to your question is probably "No, they cannot be replaced and the lamp is no longer useful after all of the LED chips die."

Mine came with about five feet of cord and chain for hanging. Adjustable? Within the limits of the cord/chain provided, you will be able to install it with the amount of drop you want, but unless you install it as a "swag", there is no adjustability on the drop once it's up.

It means that the LEDs are built in to the unit. No traditional light bulb to replace. This also means that the LEDs are not replaceable.

Yes you can. It has a chain loop at the first link. And on the mount plate.
