We have the Mini Luma, the Luma 1, Luma 2 and Luma 3, and now Philips has launched the
Luma Micro (12-46W).
Incidentally, a check through the Global Philips Lighting website suggests that some lanterns that were previously available with SOX lamps are no longer available with SOX lamps. Similarly, products previously available with mercury lamps are no longer available with mercury lamps.
The Philips Kegel range (Industria 2000 series) and Philips SGS203 were previously available with SOX options, but these options do not appear in the product code listings when you dig down (although are still listed in the overview in the PDFs). The SGS203 is now only available in SON it seems, and doesn't appear on the UK website for some reason.
This would suggest that the Iris is the only SOX lantern remaining.
