I think LightPro seems to overdrive tube a bit. The ventilation in the fixture also play the role in G/M shift especially for Kino tubes which used Full-spectrum Phosphor that can't withstand heat like Tri-band.
I've play with this kind of tubes a bit.
- Osram Studioline 55/5600 : Magenta cast, not deep in red great for green screen. Tri-band tube Magenta added.
- Osram Dulux L 55/954 : Green cast, poor skin tone. Tri-band tube.
- GE Cinema Biax 55w/5500K : Better than Dulux L in skin tone. More match to natural daylight than Studioline. It's tri-band tube.
- Philips Graphica T8 36W/950 : The best of all tube I have own. Full-spectrum CRI 97!! Match perfectly with natural daylight. Some how 5300K which warmer than Kino KF55.
GE have CinePlus tube which is full-spectrum tube similar to Kino KF55 more expensive than Cinema Biax.
Look carefully if you want to buy GE one. Cinema and CinePlus are not the same kind of tube.
