The color of my Osram HQI-TS 70W/WDL from 1988 right now I put the lamp in my tracklight and run it, to stabilize it. Right now, it don't have a halogen like color. This compared to the HQI-T 70W/WDL, like the one FrontSideBus have, which have the same Sn-In-Tl-Na-Li chemistry. Why is this?

I think all halides that are WDL are 3000k as standard, this looks the same as my HQI-T 150 WDL?
