Point-source lights create visible shimmer and defined shadows, while panel lights spread even coverage but often lose that shimmer effect — the Hydra Edge blends both approaches with EdgeField optics. The line spans two sizes across reef and freshwater spectrums.
Why Blend Point-Source and Panel Lighting
EdgeField optics spread light evenly across a wider footprint the way a panel does, while preserving more of the natural shimmer and dimensional look that point-source LED clusters are known for — a genuine middle ground rather than a compromise between the two styles.
Choosing a Model
- Hydra Edge 44HD LED Reef Light — the standard-size reef model, built for tanks that want EdgeField's even coverage and shimmer in a mid-size fixture.
- Hydra Edge 44HD LED Freshwater Light — pairs EdgeField optics with a spectrum tuned for planted tanks, bringing the same coverage benefits to freshwater displays.
- Hydra Edge 68HD LED Reef Light — the largest fixture in the line, scaling up to 68 LEDs for bigger tanks while keeping the same EdgeField optical approach.
Setup Tips
- Mount with the C-Bracket Mount for rim clamping, or the Hydra Edge Hanging Kit to suspend above the tank instead.
- Acclimate gradually when installing over an established tank rather than running at full intensity immediately.
- Choose the 68HD for wider tanks needing more coverage than the 44HD provides on its own.
