I just finished a rounded flagstone patio extension with fire pit in my backyard. I'm wanting to light the floor with very subtle lighting and inconspicuous fixtures. I was hoping to use something similar to a deck light that is very small that I could mount flush on the outer edge on the flagstone to project light outward toward the fire pit. Can the Volt deck lights be mounted this way or are they only meant to be mounted vertically and project light downward? I'm open to other suggestions as well. Thanks for your help!
