I have 2 fugerays (seperate tanks) and lots of water movement - TONS of shimmer effect! Looks great.
The light on the reef looks "whiter" because it has more blue in it, probably 10,000k plus light. The Ray2 is around 7,000k, a lot more natural light - look at your plants with each one, under the Ray2 they will be much more green, under the Reef they will be a little washed out but the water will appear "whiter", sort of a glare effect.
I have the Fugeray so I can simulate the same effect by turning the blue moonlights on or off. It is totally personal preference, if you want the bright glaring white reef style light the Ray 2 comes in 10k + actinic also, but the 7000k is better for your plants.
