I often wonder why these lights are left out of conversations dealing with high end led options. As stated there is zero disco ball with the Mitras, spread is excellent and colors are amazing. I have a Radion g4 pro as well. Also a great light but you do need the diffuser if you want blended colors. Not sure you can go wrong with any of them. Good luck with choosing.If you are having a problem with the so called disco effect, and are considering the Radions, or Orpheks, why not try the Mitra LX 7206 lights, as there is no disco ball effect as they use parabolic light diffuser in each puck like the M/H reflectors, and they have a larger light spread then the Radions, and a little less then the Orpheks. All three of these lights are excellent lights, and all will grow any type of coral you want to put in your tank, so good luck with what ever lighting system you choose.
