Purchased for our new home that is currently being built.  So, in all fairness we have not seen this installed or lit up.  Will update with those photos and info once we can install. 
The color inside each ring is actually more of a shiny rose gold color rather than the gold as appears in pictures.  Because of that, we are actually going to see if they will work in a different bathroom than what we originally intended.  
It’s cool and different but will have a better final assessment once we can see it installed and working.  Stay tuned......
