The Bright Sun UV Jungle was developed especially for reptiles from tropical and forest regions. It has a slightly lower UV performance as the Bright Sun UV Desert to account for the different conditions in the natural habitat of these animals. Branches and leafs in the forest will filter quite a lot of UV and the animals will not experience the full intensity of the sun. In addition it has to be considered that aboreal animals will usually have the ability to get quite close to a lamp inside a vivarium. Since UV radiation is potentially dangerous and the UV intensity is at 10 cm distance 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. The colour temperature is with 4000K 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. Ballast necessary!
