Ceiling lighting is one of the most difficult ranges of lighting to categorise. There are so many different options available so to split them into types is tricky. A suspended pendant light is more or less what the title tells you - it's a pendant (single or multiple flex but from one ceiling rose) with a longer than normal suspension, either braided or rod for example.
Unlike single pendants they are more suitable for higher ceilings or large open areas - these pendants will be wide and big for visual impact and style and will work well in spaces with high ceilings, double height areas and of course vaulted ceilings with exposed roofing trusses.
Suspension lights will often have more than one tensile wire in addition to the cable flex. These wires can be adjusted when you install your fitting according to your individual room requirements. Wide drum or bar lights will have these tensile wires to ensure the shade remains level and doesn't sway about the breeze from someone walking by - not something you would want to happen!
With many lights they give the illusion of hanging unsuspended as the wires are near invisible providing ambient and directional lighting for dining room tables. Nothing like a bit of theatre at dinner!
