JBL SOLAR NATUR T8 25W (9000K)

Daylight full-spectrum tube for freshwater aquariums • Especially bright tube for all aquariums. • Excellently suited for Lake Malawi and Lake Tangayika aquariums. • Inhibits growth of algae through full spectrum equivalent to sunlight. • Fully natural colours through 1 A colour rendering index (very good). • Colour temperature 9000 K. • CRI 90+ Why full spectrum? Aquatic plants and corals from the reef top are adapted to full sunlight. A look at the natural environment shows that aquatic plants are almost exclusively found in sun-drenched, clear waters in shallow depths (max. 3 m). Even most of the coral species kept in aquariums are from shallow depths where the penetration depth of light is not a significant factor. All visible elements of light penetrate with equal strength to a depth of 6m! Therefore plants and aquatic animals in an aquarium should have lighting which is as close as possible to sunlight. The JBL SOLAR fluorescent tubes (with the exception of the SOLAR MarinBlue) have the great advantage of having full spectrum light. A closer look at the spectrum shows that the individual spectrum sectors of the tubes do not drop back to zero between the peaks (lighting peaks) but display all spectral sectors over the entire range from blue to red. Scientific research institutes e.g. the Institute of Marine Sciences in Kiel (GEOMAR) work with the JBL full spectrum tubes in tests in natural saltwater into the global warming of the oceans. This is convincing proof of the excellent quality of JBL SOLAR tubes! Lighting duration: Lighting an aquarium for approx. 12 hours a day is considered the most suitable length of time for plants and fish from tropical regions. Any special requirements of individual species should also be taken into consideration. It is important to note that insufficient light intensity cannot be compensated for by extending the length of time an aquarium is lit. Taking a ""lunch break"" in the lighting exposure is unnatural and interferes with the biorhythm of the plants. Lighting configurations: In the case of an aquarium hood with
