All I can say is firstly, that lamp brightness is a very poor indicator of power level

I strongly disagree. Radiation from a straight filament of an incandescent light bulb can be a better power indicator than the ADL5391 analog multiplier.  If the filament is coiled it will not convert the power of higher frequency components to heat, hence underestimating the true power (not overestimate it).

and the video camera does not necessarily relay by video an accurate brightness or colour intensity level to that observed at the bench.

I agree very much

As to whether the signal generator could light the bulb to the brightness as observed by the team at the bench, only the team can determine this. I do not think and hope that the team had any intention to deceive us. Some experimenters have prematurely shouted OU and experienced disapointment later, when all build checks, measurements and computations were weighed-in. This may be the case and an admission to this would IMO deserve respect from others experimenters.

I agree, if anything an admission of premature conclusion would increase their credibility in my eyes.

These are triacs (thyristors at best)!

Pure and applied logic: Watched very closely the visible silver part on the heat sink looks rather like a (smaller) TO-66 than a (bigger) TO-3 package when compared with the size of the screws and switches. TO-3 (although bigger) would also look more flat in overall shape than TO-66. Triacs are available in TO-66 packages (e.g. RCA 16410, RCA 40430, TAG 265). Transistors are also available in TO-66 packages. But since there was obviously a heat problem with these parts (heat sinks with fan), and TO-66 is a smaller version of the TO-3 package the use of smaller TO-66 transistors makes no sense when there are bigger (and therefore more loadable) TO-3 transistors commonly available.

That means one more puzzle piece in place.

Another puzzle piece to put in place: A triac is not the equivalent of two inverse-parallel thyristors. The gate of a thyristor has to be always positive in respect to the cathode in order to fire. The gate of a triac works in both directions.

So keep on doing this jigsaw puzzle ...

  So, the most practical idea is to replicated the yoke device, as it's the one that may have the best chance of going in the right direction.
  Even the less than blinding light given off by the yoke in the video lighting the 150 watt halogen bulb is not too bad for 5 watts of input power.
  What I have noticed with my yoke ferrite core is that they can output much more current, than the even bigger air cores, given the same input. But, it is a hot circuit, and not "cold electricity". The shock from the sparks of a yoke core running on 12v or higher hurt, and can also burn quite badly if prolonged.  The transistors heat up, the Cfl bulbs heat up as well. So, there is more power behind circular ferrite cores compared to the open air cores, which may best be used to light the gutted Cfls at higher voltages and frequencies.

Any closed magnetic circuit is more efficient than an open one.
Also, it is important to keep in mind that electric current alone is not energy nor power.

P.S.
If you have a schematic diagram and a scope, then I can help you eliminate the heating of this transistor.

Maybe. It is impossible to tell by the package type whether they are thyristors, transistors or triacs.
An operational principle of a circuit is much more revealing about elements being used in it....or even a scopeshot.
