My light fixture has 6 bluemoon LEDs in it. I like mine. They're not too blue like others I've seen but the light kind of dissipates through the water column and the light ends up looking blueish-green. Its kind of weird but it looks neat. Having 6 means it pretty much covers the span of my tank (6 foot tank) although like predator said they can look kind of "spotlightish." With single LEDs though, you can't really get away from that.
