Edison Light Bulbs

I just got a sudden urge to make something like this. I really like the way it turned out. As per usual, the materials are procedural without image textures.

I still don't know how to get a nice wireframe render. any tips are appreciated

This the is first comp I made but decided to do a single bulb afterwards. I used the Topaz Labs Denoiser for this and was pleasantly surprised with the results
