4 X M-60S units on a 5ft tank in Taiwan
The left figure shows a 150cm (5ft) tank newly established few months ago. The tank owner temporarily used a 3ft traditional metal halide + T8 lighting fixture before switching to our LED lighting fixtures. The old MH fixture with two 150W bulbs could only cover about 60% tank area.
Four Advance version M-60S units mounted in parallel. One Master unit and three Slave units were connected by signal bridging cords.
The four M-60S units offered efficient light of high penetration as well as brightness which is comparable to the old MH fixture. This satisfactory result is obtained without further increasing the power consumption (92Wx4=368W for LED fixtures, 360W for MH+T8 fixture). The homogeneous light spread over the whole tank should be considered when comparing the two lighting options. At the similar power consumption level, our LED fixtures certainly defeat the combination of MH+T8 either on brightness or light coverage. Another noteworthy advange is that the light intensity and color are now programmable with the ALC system. Different scenes can be therefore obtained in this tank during the light period in a day!
