This 100,000-gallon tank at the Steinhart Aquarium replicates quiet salt marshes to turbulent rocky inlets. A crucial part to the California Coast exhibit is the multiple level viewing areas.You can stroll the surface walkway to smell the seawater and then head below to see what lives in the sanctuary's strong, nutrient-rich ocean currents. A mixture of W2KS Cielux Amazon Sun and Tuna Light Blue spectrums were chosen to mimic natural sunlight while the tight beam angle provides the optimal levels of light for the living ecosystem below the surface, without spilling light onto the pedestrian walkways. The combination of superior color rendering with a single point light source makes the W2K the perfect solution for the demanding and varying depths of this exhibit.
