I had a few issues with the light, which were mostly personal preference I think. First I really was not that impressed with the spread of the light. Dont get me wrong it is a fantastic light but I felt that I needed the intensitiy to be crank majority of the way up to spread out over the tank correctly with the blue I was looking for. Also the shadow effect, which is awesome to see, made for some really dark parts of the tank and depending on your tank's aquascape it could be kind of a nuasiance. My biggest issue though was controllablity. Unless you have a RK or an APEX with the ALC or VDM you cannot control the light, which is what the w360 was created for. If you do have the RK or APEX the module need to run it will be about another $70 - 80. Lastley the gooseneck did not make for a clean look. I have my tank in the living room and it just looked sloppy on the tank, I actually agreed with my wife on this one. Again, this is just my opinion of the light. I have seen beautiful tanks using them, but it just was not for me. I would recomend seeing one in use in person to judge for yourself before buying one though.
