Really hard to identify your assumptions till they are violated. Everything you try has like 10x more unconscious than conscious assumptions.

I designed and printed a whole 3d part on the assumption that a lightbulb has a roughly hemispherical beam. In fact the beam is like a 30 degree cone and I have the thing designed so the beam points 90 degrees off from where I want it 😑

Otoh good news that it is such a narrow beam it will work very well even without much collimating once I turn the design 90 degrees into the intended light path

Even this thread has a hidden wrong assumption. The beam is not narrow because of an integrated reflector. Looks like it’s the glass shape itself and natural beam pattern of the filament. Hard to tell.
