The Bright Sun UV Jungle was developed especially for reptiles from tropical and forest regions. It has a slightly lower UV performance than the Bright Sun UV Desert, taking the different conditions in the natural habitat of these animals into account. Branches and leaves filter quite a lot of UV, so the animals do not experience the full intensity of the sun. In addition, it has to be considered that arboreal animals will usually be able to get quite close to a lamp inside a vivarium. Since UV radiation is potentially dangerous and the UV intensity at 10 cm distance is 5 times higher than at 30 cm, we have consciously reduced the UV output. The spectrum was adapted to the natural conditions of forest regions. With 4000K the colour temperature is warmer than the daylight of the Bright Sun UV Desert. Tests have shown that tropical lizards, like water dragons, prefer the warmer light of the Bright Sun UV Jungle over the daylight of the Bright Sun UV Desert. The warmer light of the Bright Sun UV Jungle will also promote the colours of plants, causing a nice forest ambiance inside the vivarium.
