Some freshwater tank owners may wonder if LED light can be used for growing water plants in their tanks. Let's see the video below which recorded the photosynthesis phenomenon in a freshwater tank located at a local fish store in Taiwan. One can clearly see numerous oxygen bubbles generated by the plants in the tank showed at left side. This tank uses two units of Blaze series Advance version M-120P. The video was taken 30 mins after the light being turned on in this tank. This is definitely a reliable evidence to support the feasibility of LED light on growing waterplants. (Photo and video are both offered by Cozer.)
The photo shows an elegant and neat freshwater tank with a dimension of 120cm x 45cm x 45cm. This tank locates in a local fish shop called "哲園水族" in Taichung city. The lighting source of this beautiful tank is a Polar version M-120P unit. As one can see from the photo, the light spread on this tank is quite homogeneous, showing no dead spot within the tank. The owner of this tank told us that he is very impressed with the vividness of the scenery brought out by this fixture. He also likes the color temperature of the light which is composed by 7,000K cool white and 4,000K neutral white LEDs in 2:1 ratio.
We are proud to announce the newly developed mounting system for hanging multiple M-30 units. As you can see from the figure, a combination of acrylic legs and aluminum tracking bar make it possible for hanging multiple M-30 units above the tank in parallel. According to our test on a 3ft long tank, three M-30 units being hung in this way could give a even more homogeneous light spread than using a single M-90 unit. The light could cover a larger width (>2ft). When using multiple master units, one can even simulate the sunrise from one side and sunset at the other side by setting different sunrise times for various units. This system is scheduled to be formally released in August, 2012. The formal color of the aluminum tracking bar will be silver.
