Short description of error
I'm using a Spot lamp with a DupliVerts, but the reflection of the dupli seems wrong.
The reflection of the dupli lights are only in the range of the original Spot lamp :


Exact steps for others to reproduce the error
Open the file and render the bottom view.
In the Lamp properties, play with the size of the spot to hide or reveal the reflection of the dupli lights.

Sorry if it's not a bug and thank you for your hard work !



Spot lights don't work well with non-zero size, not just in Cycles but the light geometry as defined by Blender seems problematic.

The spot cone starts with radius 0 from the center of the light, but it should start with a radius large enough to encompass the size of the spot light, otherwise part of it will be cut off in reflections like this.
