Hey Guys I'm talking about the leds that Shawn asked about at the opening of this thread. Everything I've been talking about is just the way they come.

mr 16 fixture
 

I bought a 12 volt MR 16 fixture for a track light at Home Depot. I paid about $6.00 for it. After throwing away all the parts I didn't need, I ended up with a MR 16 light fixture with a locking knob, round glass cover for the bulb and a frame that fits into a hot shoe. It doesn't lock into the hot shot, and I had to twist it 90 degrees, however..
