What is a Purple Light Bulb?

A purple light bulb is a type of bulb that emits a purple or violet light. These bulbs typically use an LED light source and are available in a variety of shapes and sizes. Purple light bulbs are often used for decorative purposes, but they also have a number of practical applications.

The Science Behind Purple Light Bulbs

Purple light bulbs emit light with a wavelength between approximately 380-450 nanometers, which is in the ultraviolet range. This type of light is also known as black light.

Purple light bulbs are often used in nightclubs, bars, and other entertainment venues to create a vibrant and energetic atmosphere.

Practical Applications of Purple Light Bulbs

In addition to their decorative uses, purple light bulbs have a number of practical applications. For example, they can be used in insect control. Many insects are attracted to ultraviolet light, and purple light bulbs emit the type of light that insects find particularly attractive. By using a purple light bulb in an insect trap, it is possible to attract and trap a large number of insects.

Purple light bulbs are also used in forensics. Blood and other bodily fluids are known to glow under black light, which can be useful in crime scene investigations. Purple light bulbs are also used in the printing industry to check for the quality of ink on paper.


In conclusion, purple light bulbs are a unique and versatile type of light bulb. They are commonly used for decorative purposes, but they also have a number of practical applications. Whether you are trying to create a lively atmosphere in a nightclub, or you need to attract and trap insects, a purple light bulb may be just what you need.
