Yes. Pet aquatic turtles need access to appropriate UVB lighting when they are housed indoors. UVB supports vitamin D3 production and calcium metabolism, which are important for healthy bones and shell development.
Can UVB shine through glass?
No. Glass and plastic block useful UVB. The UVB source needs an unobstructed path to the turtle, while still being installed safely according to the lamp and fixture manufacturer's instructions.
Does a turtle need both UVB and a basking light?
Yes. They perform different jobs. UVB provides ultraviolet radiation, while the basking heat source creates the warm, dry area an aquatic turtle needs to leave the water and thermoregulate.
How often should I replace a UVB bulb?
UVB output declines before a bulb necessarily stops producing visible light. Follow the manufacturer's replacement interval or measure output with appropriate equipment.
