I would say that the cell phone pictures intensify the spot light effect. Also, the colors are not as blue as you would think 20k is supposed to be. I had mixed feelings about using 20k but after reading some reviews I decided to go for it. Plus, I have used tape to block out some blue leds to get the reverse ratio of white to blue that is supposed to be 12k. I prefer the 20k bulbs. However, I would like to try those 7 led bulbs from rapidled. I like the using spot lights now. Recently my rbta decided to move and pointed the light where he was. In my other tank with t5's I had the same thing happen and the rbta moved behind some rocks out of the light. Of course you can't refocus the t5's. I also think the shadows on the overhangs give the tank more dimension. Plus, the shimmer is cool.
