Great place to start. Pick your wattage, pick your ballast, find your bulb. "PPFD" (a.k.a. PAR) value is the stuff your photosynthetic organisms actually use.

Of course "look" is always subjective and pictures are often extremely misleading. You pretty much have to see the bulb in action in person for an accurate representation.
