Which model HD light is best for my aquarium?

AquaIllumination has 5 different models of our Hydra HD series lights.  The Prime FW, Prime HD, Prime Fuge, Hydra 26HD and Hydra 52HD all share the same programming features through myAI. They only differ in physical size and number of LEDs contained within the given light.  Want more information on the HD series and how they stack up against the competition?  Please visit our Light Sciences
