Incandescent bulbs, the most commonly used in homes, emit small amounts of UV light. The UV light emitted by these bulbs is so small that it is impossible for human health to be noticeably affected. Incandescent bulbs don't cause sunburn or help people or animals absorb vitamin D. These bulbs only emit UVA rays.
However, plastic materials used as light diffusers could block the passage of radiation. Both incandescent and fluorescent bulbs emit UV radiation, but the levels are low compared to reptile bulbs for sunbathing or tanning. The most powerful source of UV radiation is the Sun. All you'll need is a light source and colored cellophane wrapping paper to create a makeshift UV light source.
Some scientists have expressed concern about the impact that these lights have on human health throughout life, but the UVA light these bulbs emit is too small to have an immediate effect, such as sunburn or eye pain. Ultraviolet light hits the coating when it is fluorescent and produces white light (a mixture of many different colors). Because this fluorescent material is not 100 percent efficient, some of the UV light could pass through it and mix with the white light. In addition, UV lights are used to detect different materials, for example, at the scene of a crime or in an escape room.
Holes in the ozone layer have increased the amount of ultraviolet light reaching the Earth and the organisms that live on it. If you want to use a white LED and receive UV light, just block visible colors and let UV light through. Different floppy disks use different materials and this round disc could allow UV rays to pass through and block visible light. Reptile owners, for example, can use artificial UV bulbs to provide them with vitamin D, and small amounts of UV light can help combat seasonal affective disorder.
UVB bulbs, also known as reptile pilgrim bulbs, emit considerably more UV rays than fluorescent or incandescent bulbs and are usually found in pet stores.
