I have now made Mark 2.

I stripped everything down and carefully parted the wire so as not to break the pins. I ended up with one wire all positive and one wire all negative.
I decided to use the original tube because it fits the end of the lens nicely. I then put one wire with one set of legs on the inside of the tube and one wire outside, and taped them in place. I put a hole in the tube and pulled the end of the wire through ready for connection.
I slightly tilted the bulbs inwards to allow me to get closer to the subject without any doughnut effect.
All now works brilliantly accept for one major problem the white balance I can't seem to correct this either in camera or in software without losing all colour.
Example below.
