I've noticed that my Philips MHN-TD 70W/730 Essential, produces a halogen like yellowish white 3000K color, while my Osram HQI-TS 70W/WDL Excellence produces pinkish white 3300K. The Philips lamp also have higher CRI at Ra=70 compared to Osram Ra=67. Is there a difference in chemistries between the two lamps?
