I considered it when I did my first led tank. I had big colonies and too many shadows. I got some very narrow white strips that did light the shadows up, but the light didn't spread up from the bottom edge of the front of the tank fast enough. And although they didn't have great PAR they weren't dimmable and they just didn't look good. So I gave it up. That was 4 years ago. Somebody might find a better led strip now.
