How can I safely replace a light fixture above a stairwell?

Question

In my 1911 home, there is a stairwell that has a 180 degree turn with a landing, and there is a light fixture directly overhead (centered over the railing) that I would like to replace with a pendant light. When I'm standing directly below it (halfway up the second flight of steps) the ceiling is about 3 feet out of my reach. I imagine there is some standard approach to doing this type of work (someone installed that light in the 1950's).

How can I get a stable ladder or platform in place to safely work on that fixture?

The second story ceiling is 8 feet 6 inches above the floor, as shown in this photo:

On the other side of the railing, the distance from the fixture to the closest step on the first flight is about 15 feet:

This is what I intend to replace the fixture with:

Answer 1

You can try this type of ladder. It allows for a configuration like this on a staircase:

Here is another option that might work as well.

Answer 2

Same problem - I am looking at using 2 little giant ladders and a metal work plank to get up there. It doesn’t look like fun. I did watch a video were a platform was built in the stairwell and then a ladder placed on that. Didn’t see fun either...

How about coming from above and installing a DIY chandelier lift? See this video about it: https://www.youtube.com/watch?v=9Xoc6VXUjj4

Most hardware stores sell bulb changing extension poles:

I can't tell from the picture if there is a decorative shroud over the bulb; if there is I would change the light fixture.

I had my GC put 20 year LED puck lights in hard to reach areas in my home (indoor and outdoor). You might consider this too if it fits the rest of the decor.
