How to create an object with both emmision and diffuse or reflective properties? Imagine two opaque plastic spheres with small light bulbs inside of each that aren't too bright.  They should both emit light, but also be partially illuminated even more by the light emitted from the other one.  So, hiding one of the spheres should make the other less bright and vice versa.  I would prefer to use the Cycles renderer.

It seems like I can only choose between using emission or diffuse material.

P.S. I'm a newb at Blender but know the basics.
You can plug a Texture Coordinates node from Reflection to Mapping node, mapping node to Math node set to mulptiply connected to ColorRamp and connected to another Math node set to multiply plugged in a Mix Shader node, in the Mix Shader connect Emmision Shader and another Mix Shader With Diffuse as the First Shader and With Translucent as the Second shader
