I am hoping this is an easy question. I just typed a really long thread and this forum slapped me in the face as I tried to submit it.
I have found some really good answers to questions in the past on this forum so I thought I'd seek help here.
My project consists of refurbishing the reflector bowls of some HID projectors. The original coating is a Vapor Deposited Aluminum, and like most of these applications they are burned in areas and not as reflective as I want them to be. (I bought them with the following purpose...)
I am building an Electroplating machine (For other hobbies too) and am looking to plate Gold onto the reflectors.
I'm wondering what color the light will be of a typical HID bulb if it is reflected by Gold (Au)?
I am also wondering if the luminosity will take a hit by the lack of blues and greens being reflected?
Here is a graph showing the wavelengths' reflected by Gold and a typical spectrum taken from a couple of fairly common HID bulbs...
I will be using a photometer to measure reflectance based off of the same light source using different coatings or materials. Different tests are to be conducted using the data yielded from a spectral reflection at a set distance to measure the lux.
My project will consist of "before and after" results from different reflector-bowl conditions/coatings and with other, popular cars with known projector/bulb/ballast options as a sort of independent variable to find comparable data.
