Clear Glass Shaded Triple Bar Pendant - Two Shade Options

Can the cord be adjusted to any length you want? Can they be used on a non-dimmable switch?
The flex on each pendant can be reduced as required in the ceiling plate. This fixture can be used on a regular switch or dimmer, or pretty much any electrical connection.

Silly question - is the nickel option the lighter or darker of the images?
The lighter metalwork is nickel, it is a warm silver coloured finish.

Are shades available separately?
They are only available as a complete unit, other shades may not fit the fitting as they have not been tested.

Where along the bar is the electrical connection?
The connection is in the middle of the ceiling bar.

I am looking to fit this fitting to a pitched ceiling so I wanted to know If the length of each cord can be altered/shortened when installing?
The flex can be shortened to your desired length at the time of installation.
