I'm wondering ... are Daylight Deluxe tubes halophosphate or triphosphors? I remember there has been discussions on the Gallery part concerning /DXs, but I can't find them.
Anyone knows? 
The DX phosphor blend is not rare earth based. There are the mercury lines, but Osram Sylvania's Daylight Deluxe is quite smooth with more output in 650-750nm range.
CCT: 6500K CRI: 88, so the CRI is actually better than the 765 triphosphor blend, but probably not the efficacy.
