BB+LS in PT Matrix

Well, it took a bit of butchering and glueing but all this talk of diving lights motivated me to finally fit that LS into the PT Matrix. So, I used the cut-down base of the standard halogen bulb module, fitted a dat2zip BB400 on top in a protectice "cage" and fitted a standard 1W LS on top of this. With the LS heat sink screw groove lined up with the internal Matrix location ridge I now have a "drop-in" for the light. Everything nicely sealed with clear silicone. A foam ring at the base keeps the light off until screwed in. Now to see how durable it is...
