It's a cool idea in theory. But just like the currently used bulbs, it's not just the spectral output that you see, i.e. 10,000 K but when it fills the whole range. I "guess" they've done those tests on these but then again wouldn't they have some prototype tanks showing before and after of some acros, monti's (for the dramatic effect), and others. I know I have a little flashlight you shake and it is amazingly bright for how low of wattage a LED is. I use a red one to look at my tank at night.
