Redsy,
I found them to be a liitle lighter, but much more "aukward" (sp) than a traditional fiberglass ladder.
I found them harder to carry, and they really don't extend and manuever as you would think they do.
This is my opinion of them only.
For Chandeliers of that hieght, if you do alot of them, it may pay you to use bakers scaffolding. One guy can set it up, and I found alot less chances of scratching floors than setting up a big ladder.
Dnk........
