Hydra26 hd changing spectrum on ramp down

[jacksin]

I have 2 Hydra26HD and when they are ramping down there spectrums are different. You can see it in the reflection on the screen top. One half is very blue while the other is mostly violet. I don't see much of a difference until very late in the ramp down cycle. AI sent me a new light and this one has a very white appearance near the end of the ramp down cycle.
So, I have 3 Hydra26 and they all produce very different spectrums near the end of the ramp down time. Does anyone else notice this? How close are at the spectrums during operation, I have no way of knowing. The corals seem very happy.
