In the rhythm of nature!
Aquael Leddy Tube Sunny Day & Night 2.0 lighting module designed to illuminate freshwater aquariums, which simulates the natural, diurnal cycle of light - morning, day and night. The light perfectly conveys the colors of the fish and stimulates the growth of plants. It is characterized by low energy consumption, very strong luminous flux and high color rendering index.
Day&Night Energy-saving For the freshwater aquarium Modern LED lighting Can be used to replace the T5/T8 lamps 2 years guarnree

Product description


Leddy Tube Sunny Day & Night 2.0 contains carefully selected LEDs that ensure perfect illumination of the aquarium, guaranteeing excellent living conditions for its inhabitants. It can be installed in Aquael covers and lamps. Thanks to the use of T5 / T8 accessory adapters, it can also be installed in any cover or lamp dedicated to traditional aquarium fluorescent lamps. The accessory DUBLED hanger allows you to add an additional module to the lamp or cover and thus increase the illumination of the tank.

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).

LEDs installed in the LEDDY TUBE SUNNY D&N module emit light with a color temperature of 7000 K. This ensures good conditions for aquarium plants and guarantees faithful reproduction of colors of all inhabitants of the aquarium.

Modern LEDs vs. traditional fluorescent lamps, incandescent bulbs and compact fluorescent lamps

Properly selected LEDs are the basic source of light in modern aquarism. They effectively displaced the previously used fluorescent lamps, incandescent bulbs and compact fluorescent lamps from the market. Compared to them, they have a number of advantages. They allow for a significant reduction in electricity consumption, because by producing the same amount of light as fluorescent lamps, they consume up to half as much. And this translates into both lower electricity bills beneficial for the aquarist’s pocket and environmental protection. They do not often have to be replaced with new ones, because they can work up to 15,000 hours, which again is associated with a large saving of money, environmental protection and less labor intensity. At the same time, they do not unnecessarily heat  the water in the aquarium, they shine directionally only towards the water surface (so you do not need to use additional reflectors), besides, unlike traditional fluorescent lamps, they have a two-year manufacturer’s warranty.

Why do we illuminate the aquarium?

There are usually two reasons. First of all, the tank is nice, that is, it looks natural. The light is to make the fish and plants have beautiful, appropriate colors for a given species, and the whole will be an unquestionable decoration of the room. The second goal is equally important – the vast majority of aquarists want to have healthy, well-growing plants in the aquarium. And plants need light to grow for 10-12 hours a day, which is the “drive” of photosynthesis – a natural process as a result of which they transform inorganic compounds into organic substances necessary for their life. Thus, properly selected light is to guarantee at the same time that the aquarium will look nice and the plants will grow well in it.

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.

How much light in the aquarium?

How much light does the aquarium require? It depends on what species of plants we are going to grow in it. In terms of light requirements, they can be divided into three groups:

Group I – shade-bearing species, e.g. “pelia”, mosses, winged microzorium, screw diver, some compact (e.g. aponogetonolist, Wendt’s compact, Backett’s warbler, Malayan warbler), anubias.

Group II – moderately photophilous species, e.g. spherical twig, water tintland, rhododendrons, tiger lotus, ludwigie, broad-leaved vodka, three-flowered vodka, monkfish, broad-leaved arrowhead, Argentine marsh, giant diver, compact, limnophils, small-leaved bacopa, Thai krina, ponikło, Japanese gloss, swordfish.

Group III – definitely photophilous species, e.g. cabombs, “glossostigma”, hemiantus.

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.
