Ethereal Lighting, by Maxspect, is high-quality lights with the top of the line integrated technology. This light is engineered with an active and passive cooling system. During the active cooling system, the fan turns on when the lights get too warm. The fan also has a built-in RGB mood light. With this, the different colors can be set to suit your environment. To control the Ethereal via a wireless connection, an ICV6 Integrated Controller, sold separately, can be used. This controller allows you to connect to different light systems made by Maxspect. The ICV6 App is preset with four programs, but you can also create your own and add it as one of your options. Ethereal lighting was designed to enhance coral growth and coloration. So, purchasing any one of these products will give a new purpose for your salt water aquarium.
