Crack on screen The Luminus - Smart LED Controller allows you to control all parameters independently and according to the user's wishes. It has two independent channels (maximum 5A per channel) with four light ranges each, allowing you to recreate daylight with sunrise and sunset effect, turning the lighting units on and off gradually (between 10 and 90 minutes). You can also recreate the night atmosphere in the aquarium, by adjusting the light intensity (from 10 to 100%). And to make things even easier, there's a mobile app available for Android and iOS devices. Through the Luminus app, the user has access to the extra Storm feature that simulates a storm condition in the aquarium. Compatible with all Tecatlantis/Aquatlantis products.If you use more than one lamp, you must consider that the current intensity of the transformer must correspond to the current intensity required for the lighting units. For example, for two 2.5A light units each, a 5A transformer is required. Supply voltage between 12V and 24V.
