In our previous article we considered theoretical aspects of reef lighting, such as the light spectrum and intensity required for growing corals and achieving their best coloration. We would now like to discuss the various practical challenges one faces when designing a LED light for the reef tank.…

Perhaps every reef hobbyist is willing to provide the “right” light to his corals – both correct spectrum and sufficient intensity are important. Before we consider how to implement this “right light,” we shall first try to understand what kind of light marine organisms get in their natural environment.…
