We would have to pay 129...
But we are considering only making light outlets for 38... And then surface-mounted spots (hallway ground floor, bathroom, kitchen)
For what exactly now? Because you write with wiring but without light bulbs? Light bulbs would actually be what is colloquially called a "bulb" that you screw into the socket. Then the spot and possibly transformer etc. would already be included...
You probably mean that the cables to the spots are all already laid? Just be careful not to deceive yourself... under certain circumstances, you won't be much cheaper with surface-mounted lights either. But it really depends on your requirements.
And in general. I also don't understand the general aversion some have against recessed lights. Especially since they can be very versatile. And of course you are not quite as free as with a light outlet but of course I can replace them later. Because of the given dimensions you are somewhat limited but it’s not like only one recessed light will fit. And here too, a recessed light is not the same as a spot.
But I am also against scattering spots like in a minefield. You just have to think and combine. One does not exclude the other.
