ᐅ Basement Lighting Design for Prefabricated Concrete Slab Ceiling

Hello everyone,

I am currently planning the lighting arrangement for the basement ceiling.

In the hallway, surface-mounted spotlights are planned; in storage room III, recessed spotlights; and the rest will have standard ceiling lights or moisture-resistant fixtures. The number of spotlights seems quite high to me (although I have no experience). What do you think about this? Smaller spotlights with a beam angle of 30-40° are planned. Does that make sense, or would larger ones be better?

Thanks in advance and best regards,

PMW

P.S.: Each of the two hallways is planned to have a ceiling motion sensor


Floor plan of a building: rooms, dimensions in cm, red pathways, lighting (ceiling spots), technical room.

I really don’t understand the hallway as it is. It’s too narrow for a built-in closet or shelving.
Why is there a corner cut out from the bottom left room?
If the doors to the rooms were positioned differently, you would hardly need this hallway at all.
It’s simply a hallway, no shelves or anything else.
Regarding the doors, you’re right, I’ll take another look at that.

Apart from the fact that I find the floor plan quite questionable and would revise it.

In the hallway, you could probably reduce the lighting by half, but to know for sure, you would need to calculate how many lumens the spotlights produce and then decide how bright you want it to be. There are plenty of lists and calculators available online for this.

In the rooms, I would base the lighting on their use. Especially in a storage room with tall shelves, spotlights might be less obstructive than LED tubes or similar fixtures. In this case, I would design the lighting so that it illuminates areas where no shelf is directly underneath to avoid the light being blocked.

I don’t understand or share the forum’s general dislike of spotlights, which can, of course, be combined with other types of lighting.

I’m open to comments—what do you think could be done differently?

Where is the staircase exit on this floor?
Is the layout of the rooms intentional or more by chance? I assume the room with the multi-utility connection is located where the street is. Why is the technical area separated?
The use of the other two rooms would be interesting.

The two corridors are awkward, but without moving the staircase, it’s hardly possible to change that—alternatively, you could have walk-through rooms.

Separating the different utility systems and technical equipment doesn’t seem logical.

You mentioned somewhere that there will be a partial basement living area. It would be helpful to know exactly what you plan to use that for.

The lower corridor extends a long way into storage room 2.

The passage next to the staircase looks very narrow. Keep in mind that sometimes larger equipment needs to go into the utility rooms, so slightly wider doors are advisable.

The staircase exit is at the bottom on the straight section toward the utility area.
The utility room is separate because I wanted the ventilation inlet and outlet, heat pump, etc., to be located at the back of the house, not at the front near the entrance door or facing the street.
Storage room 2 is purely a storage space, which might be used in the future as a hobby room or something similar.
Storage room 3 is a party room.

You mentioned a partially finished basement somewhere. It would be helpful to know what you plan to use it for.

The lower hallway extends far into storage room 2.

The passage next to the staircase looks very narrow. Keep in mind that larger equipment often needs to fit into technical rooms as well, so slightly wider doors are advisable.

Moving the staircase is no longer possible because of the ground floor layout.
The technical room is separate because I wanted the ventilation intake and outlet, heat pump, etc., at the back of the house rather than the front door side or street side.
Storage rooms 2 and 3 are part of the basement; storage room 2 is optional for the future.
The passage is wider, and the doors to the technical room are 1 m (3.3 ft) wide.
