The spectrum of my 70W 8000K MH lamp from Aliexpress Note complete self-reversal of the indium line. I've never seen such a width of indium in any indium blue lamp before. Wondering what would be the CCT of this lamp with only this indium without thallium. The thallium line is the same as in my Venture MH-DE 70W/UVS/GDX thallium lamp. Have some sodium probably as impurity from the quartz. I had to over-expose the spectrum, to capture the indium emission. Here is the same spectrum under-exposed: [img]https://i.postimg.cc/qBKBpcgq/IMG-7637.jpg[/img]
