Oh ok, maybe you have also on your new home some LED lights around 
I just saw on the Siteco website, that these lights I linked earlier are also available nowadays in 1800 K config.
This is quite interesting since 1800 K is unlike these narrow-band spectrum sodium lights, but more like ‘white light’ with really warm CCT. The blue is reduced but it is still possible to distinguish colors, like in the beamshots I shown in my 1800 K HL2X test earlier. According to Sitecos datasheet they have > 70 CRI. Some years ago Siteco used Osram SSL80 LEDs for the 4000 K config.
