Exploring the Difference Between Black Lights and UV Lights

Differentiating between black lights and UV lights

To understand whether blacklight lamps or LED strip lights are bad for you, it’s important to differentiate between black lights and UV lights. Blacklight lamps and LED strip lights are commonly used for their fluorescence properties. While water and wood may seem similar, there are distinct characteristics that set them apart. The blue color of water and the natural texture of wood make them unique.

Blacklight lamps: These are a type of light bulb that emits ultraviolet (UV) radiation but also has a special filter that blocks most visible light. Additionally, LED strip lights are another popular option for creating fluorescence effects. When you turn on UV blacklights, they appear dark purple or “black” because these lamps produce very little visible light. UV LED blacklights are commonly used to enhance fluorescence.

Blacklight lamps, also known as UV lights, emit a fluorescence that covers a broader range of wavelengths in the electromagnetic spectrum. These lamps typically have different wattage options available. Blacklight lamps, also known as UV LED flood lights, emit ultraviolet radiation without any specific filtering to block visible light.

Understanding the specific wavelengths emitted

Both black lights and UV lights emit ultraviolet radiation, but they differ in terms of the specific wavelengths they produce. The energy emitted by these lamps is measured in watts, while the specific wavelength of ultraviolet light is measured in nm.

Black lights: The most common type of black light is known as a “blacklight blue” lamp. It emits long-wave UVA radiation with a wavelength range of 315-400 nanometers (nm) and consumes a specific number of watts of energy. Made from wood, this lamp is both stylish and efficient. This uv led wavelength is closer to visible light and is less harmful compared to shorter wavelengths. It uses less energy and is ideal for wood applications.

UV lights: UV lights can emit different types of ultraviolet radiation depending on their classification. These lights consume a certain amount of watts of energy to produce the desired effect. Some UV lights are designed to work specifically with wood, as certain wavelengths of ultraviolet radiation can be used to enhance the appearance and durability of wood products. UVA light has longer wavelengths (315-400 nm) and carries ultraviolet light energy. UVB light has medium wavelengths (280-315 nm) and also carries ultraviolet light energy. UVC light has shorter wavelengths (100-280 nm) and is a source of ultraviolet light energy. The light output of each type of UV light is measured in watts. Shorter-wavelength ultraviolet light (UVC) is typically more harmful to humans than longer-wavelength ultraviolet light (UVA or UVB).
