Do pet turtles really need UVB lighting?
Is UVB lighting really necessary for pet turtles?
Yes, pet turtles need UVB lighting. All turtles that do not have access to direct sunlight will require UVB lighting. This applies to all pet turtles kept indoors.
Direct sunlight means that the light does not go through (filter through) other materials before it reaches the turtles. This is an important factor because UVB can not pass through glass or plastic. Or even through tight screens or mesh.
This means that turtles kept outdoors do not need UVB lighting, as they will receive UVB through direct sunlight. However, pet turtles that get sunlight through a glass window or curtains will still need UVB light.
Turtles need UVB light to metabolize calcium for bone, shell, and egg production.
UVB lights are available in many forms, including incandescent bulbs, mercury vapor bulbs, compact fluorescents, and tube fluorescents.
