One area of reptile keeping that has been severely overlooked is the correct provision of UV lighting for snakes, and especially those living in larger more naturalistic or bioactive enclosures. The 8watt 12/30cm ShadeDweller caters well for smaller species and for snakes whilst coiled at basking, but it became clear very quickly that the most commonly kept species being 3/90cm in length or more would benefit more with exposure that covers much more of the body, and within the light and shade method. Being longer and in the case of Royal/Ball pythons, more robust also, it is important to increase the size of area of illumination (projection zone), allow good photo and thermoregulation, which helps to ensure access to full colour vision and the ability to self-regulate D3 levels. This will allow snakes to move and behave naturally, seeking out areas of energy to use and to explore without the risk of them being exposed to higher levels of UV than is safe for them. This is a risk with the more powerful HO-T5 lamps when used in reduced height enclosures and with species that can easily climb.
