That /5K lamp is not a common variant. I'm wondering if it's filled with rare earth halides or if it's just a sodium-scandium fill chemistry with less sodium.

Max - I don't know what method they used...these haven't been easy to find over the last 15 years or so.
I worked for a company back in the day where we sold these...mainly to car dealers so they could make their car lots look nice.
