AquaIllumination (now part of EcoTech Marine) makes the Hydra LED line - wide-coverage reef lighting fixtures aimed at SPS-dominant reefs. The Hydra 32HD and Hydra 64HD are direct competitors to Radion XR15/XR30 with more individual LED clusters and slightly different spectrum.
Hydra 32HD: 30 LEDs in 5 clusters, ~90W. Hydra 64HD: 64 LEDs in 8 clusters, ~140W. Both produce dense PAR for SPS reefs.
Compact reef LED in the $200-300 range. The default budget pick for nano and small reef tanks (20-40 gallon range).
Same Mobius platform as EcoTech Radion - can run Hydra and Radion fixtures together on a unified schedule.
