Далее к Heat and temperature in terrariums

As cold-blooded animals, terrarium animals are far more dependent on light, i.e. the quality and intensity of light, than warm-blooded vertebrates. Activity, food intake, digestion and resting phases are influenced by the alternation of day and night, and especially by the intensity of the light.

Besides this, many terrarium animals associate light with heat and seek light places in the terrarium in order to „bask in the sun“. These considerations are especially important when choosing heating equipment for desert terrariums. There are differences in the yield and quality of light depending on the light source used. Fluorescent tubes, for example, provide a lot of light with little heat production, whereas light bulbs convert a major share of the energy taken up into heat and only a small share into light. The question as to which quality of light is best suited for a specific terrarium is easy to answer if we take a look at nature: For millions of years plants and animals have been adapting in a long evolutionary process to what the sun sends down to the earth .

If we look at the spectrum of sunlight (meaning the part of solar radiation that is visible to us), we recognise a very even distribution of all spectral colours. For this reason, lamps for terrariums should have a spectrum that is as close to being balanced and without gaps as possible.

Only a prism or rainbow shows the individual spectral components of white-looking sunlight

At the same time, all of the plants and animals can display their full natural colouring. Metal halide lamps (e.g. JBL ReptilDesert L-U-W Light alu (Специальная лампа для применения при содержании рептилий! Непригодна для иного применения! Этикетки класса энергоэффективности не требуется. Исключение согл. (EU) 2019/2015 Приложение IV 3. c) УФ-излучение > 2 мВт/клм) ) are the top choice for animals which require sunlight, ultraviolet light (i.e. diurnal animals) and heat. They offer a full spectrum that simulates sunlight and includes UV-A and B radiation, along with heat emission for the terrarium. The temperature in the terrarium decreases after the lamps are switched off, thereby simulating the desired nighttime drop in temperature. The JBL LUW lamps are available in three different wattages and two versions, depending on whether the animals require a lot of UV radiation ( JBL ReptilDesert L-U-W Light alu (Специальная лампа для применения при содержании рептилий! Непригодна для иного применения! Этикетки класса энергоэффективности не требуется. Исключение согл. (EU) 2019/2015 Приложение IV 3. c) УФ-излучение > 2 мВт/клм) ) or less UV radiation ( JBL ReptilJungle L-U-W Light alu (Специальная лампа для применения при содержании рептилий! Непригодна для иного применения! Этикетки класса энергоэффективности не требуется. Исключение согл. (EU) 2019/2015 Приложение IV 3. c) УФ-излучение > 2 мВт/клм) ).

The fluorescent tubes sold by JBL are known as full-spectrum tubes and come in two different versions for terrariums: JBL SOLAR REPTIL SUN T8 и JBL SOLAR REPTIL JUNGLE T8 . An essential factor in the lighting of terrariums is the UV light in the UV-A and UV-B ranges.

Depending on their origin, terrarium animals can require a lot or a little UV light for their well-being. UV-B stimulates the synthesis of Vitamin D3 from its preliminary stage Vitamin D2. UV-A stimulates pigmentation. Don’t forget that glass absorbs around 50 % of the UV radiation, so always install the lamps inside the terrarium.

The distance between the light source and the animal is another important factor: The information indicating how much radiation is emitted at which distance from the lamp is to be found on the lamp itself. If the terrarium is high, the animals can get closer to their UV source if they are provided with something to climb on.

The following applies to animals that require UV: These animals will fall ill even if fluorescent tubes emitting UV radiation are used! You'll need to mount an additional UV spot lamp, like the JBL UV-Spot plus (Специальная лампа для применения при содержании рептилий! Непригодна для иного применения! Этикетки класса энергоэффективности не требуется. Исключение согл. (EU) 2019/2015 Приложение IV 3. c) УФ-излучение > 2 мВт/клм) , or a metal halide lamp, such as the JBL ReptilDesert L-U-W Light alu (Специальная лампа для применения при содержании рептилий! Непригодна для иного применения! Этикетки класса энергоэффективности не требуется. Исключение согл. (EU) 2019/2015 Приложение IV 3. c) УФ-излучение > 2 мВт/клм) . When using metal halide lamps, please remember that they should only be operated with special electronic ballasts ( JBL TempSet Unit L-U-W ).

For all lamp types that do not become too hot, the use of a high-quality reflector (e.g. JBL TempReflect light ) is highly recommended because it doubles the light output.

Various light sources over ONE terrarium

In smaller and square terrariums, a lamp is often used which, for example, only emits light and heat without UV for spiders (spiders do not need UV radiation). For larger and especially longer terrariums, however, the same type of lamp is never used everywhere. UV spotlights only need to be positioned in some places or even only in one place. The animals actively visit this place. Since the remaining part of the terrarium should not remain dark, especially when plants are used, lamps are also needed there, but they do not have to emit UV. So you can choose lamp types that are, for example, energy saving and still give a perfect light for plants. The JBL LED Solar Natur , JBL SOLAR REPTIL JUNGLE T8 , the energy-saving lamp JBL ReptilDay Halogen and the JBL Reptil LED Daylight 12 Вт are suitable for this.

For energy savers and animals which don't need UV light

Spiders, scorpions, frogs and some nocturnal animals do not need UV radiation. Terrarium friends confirm this statement because they have successfully bred these species for many generations without UV lighting. In the Internet and in specialized books there are quite contradictory statements about the UV requirements of some animals.

If you want to illuminate your terrarium without UV radiation, the following lamp types are possible, depending on shape and size: JBL LED Solar Natur , JBL SOLAR REPTIL JUNGLE T8 , the energy-saving lamp JBL ReptilDay Halogen and the JBL Reptil LED Daylight 12 Вт .

All these lamps have in common that they hardly generate any heat and that an additional heat source is necessary when heat is required. Plant growth is also ideally promoted by all these UV-free lamps. Here, the height of your terrarium is more decisive: For high-sided terrariums, stronger lamp types such as JBL LED SOLAR Natur need to be selected.

Lighting for different terrarium types

The following contains all the relevant information about the various lighting types for each type of terrarium

Light for the desert terrarium

The desert habitat is distinctive for its extreme light. The ultraviolet light of the sun can reach the ground and the animals unchecked. Day-active animals from deserts and steppes require high amounts of light and UV, and actively seek out warm locations. Since light is associated with heat, irradiated areas are instinctively visited. Nocturnal animals, such as the leopard gecko, do not need UV light, as proven by their successful breeding for many generations. Advantage: heat zones can be set up at certain spots, so that it is possible for the animals to visit cooler regions!

The fluorescent tube JBL SOLAR REPTIL SUN T8 supplies 36 % UV-A/8 % UV-B as T8 version (63 %/12 % with as T5 version), which is the intensive UV-light suitable for a flat desert terrarium. As fluorescent tubes with high UV components only emit relatively little light in the visible range, a combination of full-spectrum tubes with a high concentration of visible light is strongly recommended. The JBL SOLAR REPTIL JUNGLE T8 is the appropriate option here. It offers ample light of full-spectrum quality in the visible range with a low concentration of UV, namely 2 % UV-A and 0.5 % UV-B.

A desert terrarium with a depth of approx. 50 cm can be provided with suitable lighting by using 1–2 JBL SOLAR REPTIL SUN T8 tubes and 2–3 JBL SOLAR REPTIL JUNGLE T8 tubes. It is vital you mount the JBL SOLAR REPTIL SUN T8 inside the terrarium so the glass panes don’t reduce the light between the tubes and the animals. This is so the animals can effectively utilise the ultraviolet light. If necessary mount a wire screen to prevent the animals from coming into contact with the tube.

Metal halide lamps which also produce ultraviolet radiation and heat in addition to visible light, are even better than fluorescent lamps. JBL ReptilDesert L-U-W Light alu (Специальная лампа для применения при содержании рептилий! Непригодна для иного применения! Этикетки класса энергоэффективности не требуется. Исключение согл. (EU) 2019/2015 Приложение IV 3. c) УФ-излучение > 2 мВт/клм) provides terrarium keepers with the best technology on the market for desert terrarium lighting and is also species appropriate for desert creatures.

Incidentally, invertebrates such as spiders and scorpions do not require any ultraviolet light. Indeed it can even be harmful to them. Here, JBL ReptilDesert Daylight 24 Вт or JBL ReptilJungle Daylight 24 Вт (energy-saving lamps without ultra-violet radiation) or the JBL Reptil LED Daylight 12 Вт are the best option.
