Re: XeVision Superpower "Ultra" 80 or 85 Watt (TBD)
Here you can find an old comparison which includes both the Osram D1 and the DL50 Fatboy bulb at 50W (and also the Fatboy at 75W & 80W).
Also, the performance of the Lemax/XeVision lX70 is actually better compared to the older lights including the barn burner. It does around 1.3Mcd when optimally focussed (they had this measured) which is around 30-50% more compared to the XeVision 75W and BarnBurner. One reason for this is the precision reflector which allows them to put the tiny tip of one of the electrodes into the focus. The arc has a much higher surface brightness on the tip. The reflectors of the older lights weren't precise enough for this.
