That's exactly the kind of handrail lighting we want to have made. In the end, it's even cheaper, at least if you want a handrail anyway. The electrician only needs to provide a power outlet, which is much cheaper than stair lighting with spotlights. We'll have the handrail made by the carpenter. The lighting (LED strip) is then integrated hidden underneath. It gives a nice light down onto the stairs, so it can't cause any glare either. I think it's stylish and also something different from those standard spotlights (which I found quite expensive with electrical preparation and all that comes with it).
