Linear LED Linkable Under Cabinet Striplights

I’m looking for some strip lighting for my media wall shelving which will be 6 separate alcoves. Would these lights be suitable?
I’d be looking for 6 sets of strip lights at approx 400mm long that can all be operated from 1 light switch.

Do these fittings come with fixing brackets?

If I have 6 lights all linked (either direct or via a link cable) how many input cables do I need - i am assuming one.

If I only need 1 input cable do I need a 6-port driver?

Is it possible to link across a 1700mm length with either a longer link cable or a load of the 150mm linking cables, Its to link the lights to a solitary wall unit the other side of hob, and to have cable behind splashback.

Hi, could someone please tell me what size the corner section is ? Thanks.

Can this be hard , and any on line instructions

What is this and is it simple to install?
