Solar lighting for your tank

[JDigital]

My parents got a couple of those installed in their new house they are building, just for normal lighting. I gotta say, they are very bright (in a good way), much better than fluorescent lighting. Can't get much closer to "real light" for an aquarium... Following lunar cycles would be a no brainer.. haha. Curious to know if you still get the shimmering effect like MH?
