The spectrum of my Osram/LEDvance HQI-TS 70W/D [img]https://i.postimg.cc/C56GZnp7/IMG-7059.jpg[/img] I don't know why Osram put sodium and indium and not just thallium, dysprosium and cesium? This would improve the CRI significantly and make the light pure white at 5600K like my Sylvania HSI-TD 70W/D.
