What am I doing wrong?

I have a spotlight. In the 3D View I can see the light. When I render it, it is not there. What am I doing wrong?

Check your object visibility toggles in the outliner:

Ok. I think I found problem. I, originally, had a lamp. I turned it into a spot. That appears to be unacceptable. I created a spot and placed it in the same position. That worked. Why, if blender allows a lamp to be re-defined as a spot, does this not work? Thanks.

I’ve always been wary of that ability…

Was your original spot in a different collection not set to be rendered?

It was the default lamp. I changed it to a spot, but it would not render. I see nothing that indicates that Collection, which is Collection 1, should not be rendered
