Here are a few facts from a old Movie Maker mag you may find of interest. Lamp Brightness Foot Candles Centre Brightness Average(BSI) ST1200 D 1.3 lens low 18 high 24 ST1200HD 1.1 lens low 25 19 high 31 24 GS1200 1.1 lens low 27 22.5 high 39 32.5

From looking at the numbers, I think I know... the sets of two numbers are meant to be values for both the respective machine's lens and a standard 1:1.3 lens (as found in the ST-1200D) so you can compare the two.
It seems to make sense: the 1200D and 1200HD both output 18-19 at low lamp and 24 at high lamp. But in addition, the 1200HD using a 1.1 lens rather than a 1.3 lens outputs 25 low and 31 high.
And again, the GS1200 using a 1.3 lens (but a stronger lamp) manages to produce 22.5 low and 32.5 high, or 27 low and 39 high with the 1.0 lens.
I guess that puts my own 1200HD (with Schneider 1.2 lens) at somewhere around 21 low and 25-26 high (my own estimate). Hmm, not bad, but suddenly the GS1200 is looking mighty good.

Hi Jan and Adrian sorry for the confusion when I typed it I had two columns spaced apart one for centre brightness the other average (BSI)when I posted it everything came together there was no way of fixing it until someone replied sorry again. ST1200D 1.3 lens lamp on low centre brightness was 18 on high 24 ST1200HD 1.1 lens on low centre brightness 25 on high 31 with a average(BSI)low 19 high 24, GS1200 1.1 lens on low centre brightness 27 on high 39 average on low 22.5 high 32.5.I hope it comes out right this time Graham
