Thanks to its wide reflector the Bright Sun FLOOD ensures a large scale illumination of terrarium and has a lower UV and light output compared to a Bright Sun UV. For a lot of forest dwelling reptiles this is an advantage as many avoid direct sunlight. Most chameleons for example belong to this group. For these animals the Bright Sun FLOOD Jungle is the perfect lighting and can be used a sole lamp as these species do also have lower UV requirements. For sun loving animals like Green Iguanas we recommend the combination with the Bright Sun UV Jungle to create local basking sites. Ballast necessary!
