UVB lighting is critical for vitamin D3 production, which allows tortoises to absorb calcium properly. Without sufficient UVB exposure, tortoises may develop metabolic bone disease and shell deformities. Indoor tortoises rely entirely on artificial UVB lighting, making proper bulb placement and regular replacement essential. Adequate UVB exposure supports strong bones, shell health, and overall vitality.
