Right, I didn't think you wanted a hood, especially not when you ordered hanging cables
Here's a picture of what I'm trying to describe. Just an empty box with no bottom where you can attack the light inside of at the top so when it is hanging the box will appear to glow without being able to see the LEDs themselves. The box would look more modern if it were darker and perfect 90 degree angles on the edges. I'm sure however you do it will look great.
What is the difference between blue and royal blue anyway?
