Randy takes the NEW EcoTech Marine XR15 Blue and performs a series of tests to find out the best mounting configuration and output settings based on real data using a PAR Meter and Spectrometer. We also make a comparison between the XR15 and it's bigger brother, the XR30, to see which option will give you the best bang for your buck when lighting a reef tank.
