Ok here's my test of the object, but honestly i think my result sucks bigtime. No matter what i did i just couldn't get it right. I hope someone else have better luck than me with this one.
Scene info
Render time: 1 hour 2 minutes
Sampling Level: 13,11
Lights: 3 + SkyDome @ intensity 15 and at RGB: 183, 194, 200
Emitters: 1 (D65 34W), 2 (Cool White 12W), 3 (D65 28W)
Textures used: Two bitmapped custom made perlin noise maps, two for the cable and the connector + one of those on the floor as a specular map.
I spent 2 hours on this including 1 hour of rendering the scene. And i know that's past the timelimit but i chose to do it like that anyways. The setup time for the different things such as materials were rather quick, the lights took like 20 min to get right and then a few small testrenderings to see that the approx materials and lights looked about right.
However there was no way i could control the level of specularity on my maps so it's overly bright and almost overexposed. Please also excuse the lowres noisemap appearing pixelated on the floor. But i was in a hurry
