The main uses for UVB bulbs include:

• Skin Disease Treatment (Phototherapy): UVB lamps are widely used in medical settings to treat various skin conditions like psoriasis, vitiligo, lichen planus, and atopic dermatitis (eczema) by exposing the skin to controlled amounts of light.
• Vitamin D3 Synthesis: Exposure to UVB light in the 290–300 nanometer range is essential for the synthesis of Vitamin D3 in the skin of both humans and animals.
• Reptile and Pet Care: UVB light is crucial for reptiles and amphibians, as it enables them to produce Vitamin D3, which is necessary for calcium absorption and bone health. Without it, they can develop metabolic bone disease.
