The surprising part is that it ends up yellow at full brightness. Mind Blown

I presume that's down to the type of phosphor used, but Max would know more about that. Wonder

Sorry for the delay, I've been extremely busy lately. In the present case, I know as much as you all do. But I'm willing to run some tests to answer any of your questions if you send me this lamp Wink
