Yes I did buy it locally. I think it was more on my part because I didn't think at the time there was a difference between garnet and red garnet. Seeing the red sand that was in the bag only helped my thought process, but seeing the after affect I can see there obviously a difference.
Garnet sand is variable. My abrasives supplier said almost all the garnet he's seen in the last year or two is more purple than red. Estes Ceramaquartz is a better alternative, IMO. Their red sand is a nice brick red that makes bichers look incredible.
I don't clearly remember what lights I had. I sold off everything quite awhile back. I just remembered they were like 8x 10k T5 bulbs or something along that line.
