It is often referred to as ultraviolet 'light,' but UV is a type of electromagnetic radiation with wavelengths shorter than visible light and longer than X-rays. ... The three different types of UV light bulb available are Blacklight Blue (BLB), Blacklight (BL368), and Germicidal.

But not all types of UV are the same. ... While UV is commonly called, "UV light," the spectrum technically falls just outside of the visible light spectrum.

Tech Tip: What Type of Ultraviolet Light Will Kill or Prevent Mold? According to our in-house technical expert, a shortwave ultraviolet light in the range of 280 to 100 nm can help kill mold and prevent its growth. Also, ultraviolet germicidal lamps can destroy bacteria, molds, yeast, and viruses.

Ultraviolet (UV) radiation is defined as that portion of the electromagnetic spectrum between x rays and visible light, i.e., between 40 and 400 nm (30–3 eV). ... Germicidal lamps are designed to emit UVC radiation because of its ability to kill bacteria.

Ultraviolet (UV) microscopy is a type of light microscopy that utilizes UV light to generate a magnified image of the sample being analyzed. As a result of the shorter wavelength of UV light than visible light, it is possible to view samples with greater magnification and resolution.

A light-emitting diode, or LED for short, is a lamp that emits light in a very narrow band of wavelengths. Because of this, LED's are far more energy efficient than incandescent or fluorescent lights, which emit light in a much wider band of wavelengths.

Luckily, “warm light” CFLs (Compact Fluorescent Lights) are okay for your eyes, as well as being much more efficient. They do emit UV rays, but a much smaller amount. You can also use LED bulbs or halogens.

The difference between an LED and UV nail lamp is based on the type of radiation the bulb emits. ... Both LED and UV nail lamps emit UV wavelengths and work in the same way. However, UV lamps emit a broader spectrum of wavelengths, while LED lamps produce a narrower, more targeted number of wavelengths.

A blacklight (or often black light), also referred to as a UV-A light, Wood's lamp, or ultraviolet light, is a lamp that emits long-wave (UV-A) ultraviolet light and very little visible light. ... Blacklight lamps which have this filter have a lighting industry designation that includes the letters "BLB".
