Demonstration of using mesh light and transmission material in Octane Render.See completed work here: [link]
Now some explanations about used techniques:
1) PMC (or pathtracing) render kernel should be used for transmission to work. Also, a lot of samples per pixel required due to presence of single compact light source. You may notice a lot of 'hot pixels' in sample renders, because only 1600 or 2000 spp were reached. Completed work done with 13200 spp.
2) Lamp model from [link]
3) All materials shown are using just RGB values, not texture maps.
Key materials are:
a) Emissive material for bulb: diffuse material with blackbody emission (4200K color temperature, 25W power - simulating real incandescent light bulb).
b) Translucent lampshade: diffuse material, with transmission assigned to desired color (dark green here).
c) Metallic parts: glossy materials are used to make reflections and glares.
4) Scene composed in Poser, rendered in Octane; blocks, lines and labels composed in Paint.NET.
