I currently have 4 personal, TN31, T10, a P60 host, and a TIR. I also have one that I just put together and I am going to sale. I have 3 in the mail to get and mod for sale, and I have an old DE-comisioned WF-500 that I was tired of putting bulbs in. I have a PD20 for work that they bought and own, but I could bring it home if I want. I almost forgot about the new light that I have in the mail for personal use, I have a Supbeam L25S on the way as well. I would say I will have 5 as of Sat. but I am willing to part with my TIR light as I just bought it to see what it was about, then I modified it with a new driver, led and copper PCB. I would say that I have only 4 right now.
