I created a light bulb for my lamp and set the spot light behind it.
The problem was that my emissive object (the light bulb) was actually blocking the spot light so it was not visable on the ground (Backdrop). The one way I found to avoid this problem was to turn of the “Shadow” in the materials tab of the light bulb so the light of the spot light shines through it. I’m still learning and I’m sure there are other ways to make light shine through an object but I thought this might be helpful.
