Jamison, I think you have an interesting idea for your tank. The only point I would dissagree on is that the LED's are NOT a "needed addition to any tank" as you said. I do agree that you have facilitated ONE way to lower their morning stress levels. You also have added benefits of looking at your fish in the dark at night. I personally feel that their are enough areas of the amazon and other natural habitats in which there is too much tree cover to allow much if any moonlight into the water. I'm sure that there ARE areas of high moonlight sometimes, though. Personally, if I caught a wild fish, I would research the exact area I caught it at and try to match that little niche of the wild to meet it's needs in a tank.
In summary, I think you have a fine and interesting solution to your room's situation of no light getting to the tank before you turn on the lights. Most of our tanks (unless in the basement) have sufficient light reach the tank that the fish do not over-react to the strip lights coming on.
I personally have my timers set to come on at 9 am and turn off at midnight. I do this so that they gradually get light to the room in the mornings, and I like to watch them late at night sometimes. They are in the dining room, so I don't keep that light on all night. They do get abrupt darkness when midnight hits, but I've never seen this freek them out a bit. They seem to be very used to and comfortable with the setup. This is not the most "realistic" light setup, I agree, but my fish do not jump around unless I bang the stand they are on, for some reason
Man, I hate when I accidentally do that!
At any rate, I think the simplest solution for those who can't get light to their tank before turning on the tank lights is to invest in a timer on a lamp across the room, as I mentioned near the beginning of this thread. I'm really glad you are doing this research on the LED's and posting your results, though! Now we can all benefit!
