How long is the chandelier for the four-story staircase?

The four-story row staircase chandelier is 5 meters long. Chandeliers refer to high-end decorative lighting fixtures suspended from indoor ceilings. Whether the chandelier is hung by wires or iron supports, it should not be hung too low to block people's normal sight or make people feel dazzling. Take the chandelier in the dining room as an example. The ideal height is to form a pool of light on the dining table without blocking the sight lines of everyone at the table. At present, chandelier hangers have been equipped with springs or height adjusters, which can suit different floor heights and needs. Crystal chandeliers are suitable for living rooms, bedrooms, restaurants, corridors, hotels and other lobbies. Commonly used chandeliers include European candlestick chandeliers, Chinese chandeliers, crystal chandeliers, parchment chandeliers, fashionable chandeliers, tapered chandeliers, pointed and flat lanterns, belted lanterns, five-pronged ball chandeliers, magnolia chandeliers, olive chandeliers, etc. There are two types of chandeliers for living rooms: single-head chandeliers and multi-head chandeliers. The former are mostly used in bedrooms and restaurants and the latter should be installed in the living room. The installation height of the chandelier should be no less than 2.2 meters from the ground at its lowest point.
