The Arcadia D3+ Dragon Reptile T5 Lamp 14% UV-B lamp is the replacement T5 tube for the Pro T5 UVB Kit and LumenIZE Pro T5 UVB Kit. The Arcadia Dragon Lamp is a bold, white, full spectrum and very bright High Output T5, UVB projection lamp for captive reptiles. The lamp represents an almost doubling of light (LUX) and has a CRI of over 95 which will you as the keeper to see your animal in all of its natural glory. For an arid species like a Bearded Dragon, the upper index basking distance (UV-I 6.00) should be set at 15 inches (35-40 cm) from the reflected lamp to the animal's back at the basking spot or shortest point. This will allow you to create 'wild-like' indexes of energy with an energy rich, wide basking zone whilst providing ample access to light and shade for natural self-regulation. The increased level of UV-B energy which is balanced with 30% UV-A ensures that this lamp is simply perfect to be used in vivarium of 24inch/60cm high or more. It will also help greatly for those that use terraria with a mesh top as the extra energy will allow light to penetrate deeper into the enclosure, providing wild-like indexes of UV-B at a safer distance. Suitable for use in ProT5 kits and single and twin HO-T5 controllers. Suitable for Bearded Dragons, Tortoises, Turtles & Terrapins.
