Those are not reflections, They are shadows coming from your light fixtures.

I would just not make the ceiling shiny.

4

how can shadows be projected higher than the fixture or the lamp
which is right under the fixture ?

in reality ceiling and floor have about 10 of spec reflection even if this does not make sense
but in blender may be this is not an exact model so
i’ll try to reduce it to zero!

Thanks

ypoissant is right, they’re shadows. Turn off the lamps associated with one of your fixtures, and you’ll see the ‘reflection’ beside it disappear.

Exactly because the lamp is right under the fixture. Think about it for a moment.

7

the fixture is a l few inches under the ceiling which create a shadow on ceiling

and it is normal to have that shadow

and after thinking about it it should even be a lot more darker than that ?
the only thing it is at hat the wrong position
it should be above the fixture not on the side?

OK RECHECKED THE LOCATION OF LAMPS AND THEY WHERE
A LITTLE OFFSET AND NOT INSIDE THE FIXTURE

SO I CHANGE LOCATION AND NO MORE BAD SHADOWS

Thanks

see pic now i got theses spot on ceiling

which i’m not certain how they got there

the lamps are under the fixutre inside and hsold not do any spot on the ceiling

what could be doing this ?

another thing is the fixture i the back whihcis not doing a lot of illumination
on the top of the equipment which is strange!
because the fixture is very close to the top there !

Thanks

Are they actually ‘lamp’ types? As in, do they project light in all directions?

Looks like specular from the light of each lamp, now.

all lamp inside the fixture
that’s what i find strange to have a spec spot
see pic

how can this be ?

Thanks

Upload the .blend …

EDIT: Set the ceiling material to receive shadows.
