The Costco "Techlite", I bubba'd this the other day with: Cheapy aluminum rings, a rubber mallet and some 6-32 mid-length screws. I'm not serious about keeping it mounted, but it was fun to to it and for only $20 for 2 lights why not? :bluelaugh: I'm assuming its 30mm around maybe a little larger? I pounded it into some 1inch rings. Anyone else bubba something over the weekend?
