After seeing that some North American F40T12 fluorescent tubes have a mixed phosphor blend like the Philips Cool White Supreme, and modern Sylvania CWX tubes, I am beginning to wonder which North American F40T12 fluorescent tubes are pure triphosphor tubes that have a similar phosphor formulation to most North American F32T8 fluorescent tubes. If I am not mistaken, I believe that GE’s SP, SPX, and CX tubes are GE’s lines of pure triphosphor F40T12 fluorescent tubes. I also believe that Sylvania’s designer 700, designer 800, and 900 series tubes are Sylvania’s line of pure triphosphor F40T12 fluorescent tubes. Finally, I also believe that Philips’ spec, ultralume, and Advantage 800 are Philips’ lines of pure triphosphor F40T12 fluorescent tubes. Can someone confirm if these F40T12 tubes are pure triphosphor tubes?

I do know CWS is base off the ultralume 41U

Now 700 series is just a halo and tri blended lamp except for halo daylight as it already in 700 series to start with.

 I know norelco made some triphosphor lamps
 In late 1970s in using european 80 series code

  Sylvania And philips T12 cool white plus is 741 phosphore
As it very close to my GE color 25 125 watt 8 footers I have
 Known as universial whites.

800 series tubes are pure triphosphor, that's for sure.
