Drs. Foster and Smith’s Aquaculture Coral and Marine Life facility is continually testing new technologies in an effort to reduce our energy consumption, while providing the best possible environment for the animals in the facility to grow and thrive.

We are currently testing a new lighting technology that is showing very promising results. We have employed Ecoxotic Cannon LED Pendant lights on one of our 6’ x 3’ coral grow out raceways, which were installed a few months ago. There are three 50- watt cannon lights mounted on a moving light rail (2- 453 nm Blue “Actinic” and 1- 12K) over a coral raceway containing mostly LPS corals such as several species of Chalice, Blastomussa coral, and Acanthastrea corals.

It’s pretty incredible to see a dramatic change in the coloration of the corals in such as short period of time, as some really “pop” now with glowing red, blue, greens, and pinks! The corals appear to be growing at the same rate as before, which is impressive to see, considering this raceway was illuminated previously with a single 400- watt 20K metal halide unit. We hope to continue testing and utilize LED technology more in the future.

Very nice. Have been experimenting with LEDs for some time myself and am seeing pleasing results as well.
