model was created in Cinema4d r20 and is made to render with arnold 5. Diffuse and specular map are included however the specular map is not hooked up or used in the render (included as optional). An .fbx is included in the .rar file for use in other applications however you will have to recreate the semi transparent glass texture for the bulb. The glass is made by adding 'transmission' in arnold renderer (i.e. transparency or refraction) to the bulb but not too much. In vray you may need to reduce the 'refraction glossiness' to remake a similar effect so you can 'see the light' through the glass (ie, it has a 'hot spot).
The light includes 3 arnold lights within the model: one in the middle to illuminate the inside of the bulb, one below the bulb to shine light on the ground, and another below the bulb to shine light up on the ceiling and to cast a minor shadow around the base of the model. Light nodes are included in the fbx file however they will most likely not function the same by default when you open them in another program.
Turning on and off the light: There is an 'on group' and an 'off group' in the light model. Simply make one visible and make another one not visible and it will function correctly and turn off the lights once you disable the 'on group' and visa versa.
An .fbx is included in the .rar file for use in all applications
