Sorry i don't know the light type or maker the landscape contractor selected it with the homeowner. I'm going to guess Kim Lighting. Good luck and thanks for the question.

What product did you use to make the bbq top?

The counter top is Bluestone 'select blue' with a thermal finish but we often use a honed finish that is smoother and more stain resistant. The edges or profile face has a rock or chiseled finish. The wall caps in the photo above have the same thermal and rock finishes.
