I gave it a shot, but it's not shiny. Others do that better than I. I changed the bracket material to a Blue Plastic Coated enamel, turned off all the lights and used "Options / Render Scene Luminance". I created a luminance with "Simple Sky" using the settings shown below. You could probably get away with 400 for Samples. For Render Scene Environment I just used a dark Plain background (16,16,16), not black.
The other render used a graduated background and 400 Samples in the Luminance.
