For what it's worth, the sunrise, sunset and traveling moon are my favorite features of the LEDs I own. I don't care about cloud cover or lightning.
I wouldn't suggest that corals care the slightest bit about sunrise/sunset, but the fish sure do. The behavoir during the first hour and last hour of the day are very different. I have 12 Anthias in the tank and they actually school for the last 15 minutes of daylight. My wrasses are much more energetic when the lights start to fade. It is fascinating to watch the distinct change in dynamics depending on the light phase.
My absolute favorite time to watch the tank is the last hour of the day. My second favorite time to watch the tank is with my morning coffee as the sun rises over the reef. Simply awesome.
My final verdict on whether the money I spent on LEDs was a good purchase or not will have to wait. Ask me a year from now. However, the money that I spent for the dimming capabilities over the equivelent cost of a non dimmable solution was worth every penny.
That said, I like the Orphek lights a lot. Just not as much as the ones I bought, but then I am biased.
