Natural light is great, but it's not always available. Maybe your house doesn't face south, maybe you live in a cave. Either way, light is how plants do there thing and it also takes a lot of energy.

Plants have a very narrow spectrum where they absorb light; so white light isn't really necessarily. With LEDs, the correct spectrum can be used thus creating a more efficient system. If we really want to get fancy, we could liquid cool the LEDs and use that heat to keep the fish at the proper temperature.
