On a grand musical concert in Water Cube at early 2009, the lighting designer intended to perfectly combine the Fountain, concert and lighting show together, he expected the lighting fixture should had stunning and variable color-mixing effects, also it was very important that its IP rating must have no problem to protected from the powerful jetting water from the fountain as these fixtures would be installed along the two sides of the fountain pool. Again, the ROXTAR met all these needs, and the audiences were all fascinated by this dreaming concert.
