Hello,
could you please help me with the placement and selection of recessed ceiling downlights?
I get the impression that some users here have a lot of knowledge. This is a bit overwhelming for me.
It concerns recessed downlights in the precast concrete ceiling, whose positions I need to determine before the ceiling is installed. The holes cost 130 Euro each without the fixtures. I find that quite expensive and therefore don’t want to go overboard with spotlights in the house.
I would like to have recessed lights only in the ground floor hallway and cloakroom. I want good illumination and don’t want to plan too many or too few. I want to be on the safe side!
I deliberately don’t call them spots, because I don’t want directional lighting. As I have learned from posts here, I want a wider beam angle and therefore floodlights. Which manufacturers are good for this? I was thinking dimmable, as I do not plan any other lighting in the hallway besides the recessed downlights.
How would you position the lights, and how many do I need?
The hallway is 5.47 m (18 feet) long from the front door to the living room wall. The dimension from the utility room wall to the end of the cloakroom / WC wall is 4.31 m (14 feet). The wardrobe cabinets probably go up to the ceiling, which changes the center of the room. I read that when planning lighting, the room center is not defined wall to wall but from the cabinet front to the opposite wall.
Thank you very much in advance!!!
Attached is an idea of mine. Does this work like this?

saralina875 Oct 2020 08:59Ikea recently started offering panels like these. However, I have no idea if they are any good.
The drivers are external. Either there is space provided in the ceiling through junction boxes or a suspended ceiling, or drivers are located in the utility room (HAR). There are many possible solutions.
The lifespan varies greatly because no one really knows what components have been installed. E14 and E27 retrofit bulbs cannot be compared to this, as the components often fail due to overheating caused by the confined space and fixed dimensions.
With an external driver, however, there is definitely better heat management, so the lamps generally meet their expected lifespan. Additionally, the driver can be replaced without having to change the lamp itself. Of course, the LEDs can also be damaged, in which case everything needs to be replaced, but this is rather rare.

The lamp you posted certainly isn't exactly cheap, is it?I think it’s more in the higher price range. Mycraft schrieb:
They are simply 5 panels with tunable white placed side by side.That would be quite easy to replicate. There is a bit more intelligence involved, though. Tunable white only adjusts the color temperature, but it usually doesn’t correct the very limited spectral output of the LEDs. It’s actually that, among other factors, which makes the light appear true to color like natural daylight. This also explains why LED lights with the same color temperature, e.g. 3000K (5400°F), and identical CRI can look very different. The difference is quite noticeable.A sideways example showing that two or three measurement parameters are not enough: a violin and a piano can both play the reference pitch A (440Hz) at the same volume (dB). But they don’t sound the same.
Just like with audio equipment where listening carefully is worthwhile, with lighting it’s better to see and experience it in person. This is more helpful for making a good purchase than relying solely on technical specifications – which are important, of course.
Yes, but that doesn’t change the fact that with 5 panels and a tunable white driver, it is still possible as shown in the picture.
Of course, it is a complex subject, and the intelligence is in the driver that can handle tunable white. Some are more advanced, others less so. And obviously, the panels must meet the same light reproduction parameters.
Tunable white is not the same as tunable white. There are significant differences. Sometimes what is sold as tunable white can really make you raise your eyebrows. You look at it and think: Seriously? Are they really serious about this?
