The LEDDY TUBE SUNNY D&N LED module is equipped with Day & Night function. It works in three operating modes: DAY / DAYBREAK / NIGHT. DAY is the basic and most powerful light to illuminate the aquarium during the day. DAYBREAK is a reduced daylight power of up to 50% plus blue light. It works well as the first mode after the night and when feeding fish – especially if you have a skittish stock. NIGHT is a blue glow that allows you to uniquely observe the aquarium after dark, including fish and nocturnal animals. Day & Night lighting will beautifully expose the arrangement in the aquarium both during the day and at night, and will also make the interior of the room in which the tank is located more cozy. Changing the DAY / DAYBREAK / NIGHT operating mode occurs after switching the module off and on with the switch in no more than 5 seconds. Switching directly to DAY mode takes place after turning off the module for more than 5 seconds and turning it back on. It is best to automate this process using a modern aquarium controller SOCKET DUO (offered separately).The LEDs installed in the LEDDY TUBE SUNNY module emit light with a color temperature of 7000 K. This provides good conditions for aquarium plants and guarantees faithful color reproduction of all inhabitants of the aquarium.Usually, the conversion of lighting power per liter of aquarium is used. It is conventionally assumed that in the case of LED lamps for growing shade plants, min. 0.15-0.2 W for each liter of water. Moderately demanding plants need 0.25-0.4 W / 0,26 US gal, and those definitely photophilous even 0.5-0.7 W /0,26 US gal.The “day” in the aquarium can fall on virtually any part of the day. If the tank stands far from the windows and is illuminated only by artificial light, the hours of switching on and off the lighting can be practically any. It is best to simply adapt them to our preferences and the hours when we are usually present in the apartment (e.g. “dawn” at 3 p.m. and “dusk” at 1:00 a.m.). We can then enjoy the beauty of our own “piece of the underwater world” at will.
