Can you use LED lights as a UV light?

Can you use LED lights as a UV light?

A fixture or bulb peaking at around 365nm will cover the entire black light spectrum. Some in the lighting business have stated that LEDs do not produce UV radiation. However studies have shown that standard LEDs do create a small amount of UV. That said, the amount of UV they actually emit is even less.

What wavelength is UV LED light?

UV light-emitting diodes (LEDs) have a narrow spectral output centered on a specific wavelength, +/- 15nm, with typical commercial UV-LED lamps emitting at 365nm, 385nm, 395nm or 405nm wavelengths.

What does NM mean in UV light?

Ultraviolet (UV) radiation occupies the portion of electromagnetic spectrum from 100 to 400 nanometers (nm).

What is 365 nm UV light for?

Our special long wave 365 nm black lights are used for inspections, finding cracks and leaks, UV Curing of adhesives and resin, just about anything.

Is UV LED harmful?

UV LEDs emit intense UV light during operation. Do not look directly into a UV LED while it is in operation, as it can be harmful to the eyes, even for brief periods. If several UV LEDs are used together and/or at high output operation, avoid prolonged exposure to skin or other tissue. …

What does nm mean in UV light?

Do UV lights grow plants?

Yes, UV has benefits for plant growth, but it can still cause damage to plants and humans if not used properly. Exposing plants to that much UV can quickly kill them. Growers should provide their plants with a full quality spectrum which emits the right amount of UV.

How many lumens is a UV light?

As a concrete example: a 10 watt UV blacklight emitting 0.5 lumens per watt will emit 5 lumens of visible light – approximately 1% of the brightness of a 40 watt incandescent bulb.

What is the difference between 365 nm and 395 nm UV lights?

Both 365 nm and 395 nm options are within the UV-A wavelength range. Generally speaking, UV-A lights are useful for creating and observing fluorescence effects, as well as for plastics and paint curing. UV-A wavelengths are safer when compared to stronger UV-B and UV-C rays.

Why is my 365 nm LED light bluish?

When illuminating a 365 nm LED, however, you will likely notice a dull, bluish-white color emitted. This is caused by visible light “leakage” where minuscule but visible amounts of visible wavelength energy (i.e. white light) are also emitted.

What is the UV-A emission energy range?

Conversely, looking at the 365 nm spectral output, you will notice that virtually all of the light energy is within the invisible UV-A range only, with emission energy tailing off before reaching 400 nm. This will maximize the amount of UV-A energy compared to visible light energy and is preferred for most UV-A applications.

What is the wavelength of light below 400 nm?

Light that has a wavelength between 400 nm and 800 nm is visible, while light that falls below 400 nm is considered invisible, ultraviolet light. Even though lights at wavelengths below 400 nm are not visible to the human eye, the wavelength value is still nonetheless very important.
