What is Black Light

UV-A, also known as black light, is a common type of light. UV-B is derived from the sun. On the other hand, UV-C has the ability to eliminate mold, bacteria, and mildew. It is frequently utilized in medical settings to safeguard equipment.

For instance, blacklights have various applications such as examining objects under a microscope and detecting bloodstains on clothing. On the other hand, UV lights are primarily used for sterilizing medical instruments and other items. Additionally, they are utilized to determine the level of contamination on photographic paper, which is crucial for archiving photos.

If you switch on a black light bulb in a dimly lit room, you will notice a distinct purplish illumination emitted by the bulb. However, what remains invisible to the naked eye is the ultraviolet light that the bulb is concurrently emitting. It is important to note that our eyes are capable of perceiving visible light within a spectrum that encompasses colors such as red, orange, yellow, green, blue, and violet.

Black light technology is easily achievable with LED technology. LED’s have the capability to emit light at various wavelengths, including the range of 385-400nm which is commonly associated with black light. However, it is generally believed that a slightly lower wavelength is ideal for achieving the best black light effect.

Exposure to UVA from black lights is considered to be below the recognized safe limits and does not pose a hazard to individuals using them, working in their vicinity, or having them in their home. UVA is believed to contribute to premature aging and has recently been associated with certain skin cancers, although UVB is the primary cause of skin cancer.
