Obviously, the 2x250W MH is much brighter than the 150W LED. However, the rippling effect is still there as the LEDs are point source lighting also.

The spectrum covered depends on which LEDs you use. I use heavily on 450nm which is the suitable for photosynthesis and 5000K for the full spectrum lighting.
