I'm pretty sure you have the older Maxspect units which are found on this tank:

The Mazarra didn't come out until the end of last year. I was looking into the Mazarra but there were a lot of complaints so I ended up with AI. The Maxspect unit you currently have is more than enough lighting for the tank that you plan on setting up as seen in the video I sent you. If you are looking into upgrading just to upgrade then AI, Vertex, and Ecotech are definitely great choices. Out of the three Ecotech is the only one currently with RGB, Vertex has the most features and most expensive, and AI is the cheapest and smallest if you plan on using the nano unit. AI will be coming out with a new fixture soon tentatively called "Phoenix" which is like two nano sols combined.
The person that first ran with scissors ruined it for the rest of us.
