Fairly recently I believe. This is from the NPR article about him:
I started the “Glamour & Headshots” photo series last year shortly after purchasing a light kit that was once used for school portraiture. I was told I probably couldn’t take any “cool” portraits with it, because of the limitations of the power pack. This made me curious about what I actually could do with it. So, I had one of my roommates come into my studio and sit for me, and it was hilarious. We had so much fun! … I started making up characters and back stories, and told my friends they were these people. …

Pretty funny and creative way to use the lighting kit.
