Quasar Grounded Tri Pin to Grounded Male T12 Power Adapter
***Discontinued

I bought two of these to replace one that came with my 4ft X-fades. One to replace the broken one and one spare, because I'm assuming another one will break at some point. The clips that hold it in place tend to come undone when it's mounted because of the silicone boot that protects the end of the lamp, which in turn causes the pin to flex and eventually break. It's just not a very good design, as opposed to everything else about the Quasars.
