Hey,
thanks for the feedback. Yes, we have now decided on an LED strip with a transformer. A socket under the stairs is now available and the transformer position is thus defined.
We already ordered the handrail last year with a groove when buying the stairs, and the electrician installed a switch in the wall for the stair ascent and descent respectively.
However, we only found time for detailed planning now. The shell construction is technically ready. Before the screed comes and we do the painting work, everything should now be prepared.
Since we have two handrails (landing stairs), we have already found an extension and a split connection to lay the cable from the transformer to the LED strip sufficiently and to use it for both handrails.
But we are wondering how best to lay the cable in the wall so that
1. it can be exchanged again without opening the entire wall and 2. how to lead the cable from the handrail into the wall without it being visible.
Are there handrail brackets available for purchase where the "screw and cable" can be fed through? Otherwise, we would ask our stair builder about this after the weekend.
The ones we saw on site were only sleeves for the mounting screw and we don't want to just visibly "stick" the cable there and lead it into a visible, even if small, hole in the wall.
Andre77 kindly already replied to me about how he implemented it, but his LED strip ends in the wall with the connection under the stairs and you don't have to hide the connection.
So the part "hiding the end of the LED strip to the transformer" still requires a solution ...
