If I just want to put a light point on the ceiling of a building, just to specify that at that point will be installed a light fixture, what category should I use ifcLightFixture, ifcLamp, or other one?
I would say use IfcLightFixture. That is meant to represent the entire electrical device. IfcLamp is only for the “bulb” that goes in it.
Thank you a lot, @jwouellette
IfcLightFixture. This however will be an increasing problem as almost all new LightFixtures have an integrated LED light source (the light source as such is IfcLamp). All lighting domain related requirements are currently specified on IfcLamp (like ContributedLuminousFlux or ColorTemperature). Thsi should be revised in IFC.
