We sell three different types of UV light bulb, and (here’s the important bit) one type is not suitable for all uses. A blacklight blue (BLB) light bulb won’t help you kill flies, just as a germicidal UV tube won’t help you detect forged bank notes. Once you’re aware of the different types of UV lamp and what they should be used for, picking one will be a lot easier.
With that in mind, here’s everything you need to know to buy UV light bulbs in confidence.
What is different of UV Light, UV-V light, UV-C light, UB-B light, UV-A light? UV light is in the spectrum of 100nm to 400nm. This is just below the visible light spectrum of 400-800nm. It is divided into 4 parts, UV-V at 100-200nm, UV-C at 200-280nm (for example call as 275nm uv led, 275nm led, uvc led, 265 nm uv led, 250 nm uv led, uv-c led, uv-c led 254nm, 254 nm uv led, 275 nm wavelength), UB-B at 280-315nm and UV-A nearest the visible portion at 315-400nm (in the UV-A spectrum, typically 370nm, This light be Called as black lights because the light cannot be seen and appears black).
UVC energy is a commonly used sterilization technology that has been shown to inactivate a wide range of pathogens (e.g. MRSA, C. diff, E. Coli and Pseudomonas). For many years, UV mercury lamps were considered the best choice. However, lamps have several limitations, including low activity at refrigeration temperatures, fragile construction, long warm-up time, risk of mercury exposure, and limited UV emittance at 254 nm. In comparison, UV light-emitting diodes (UV LEDs) can be configured to emit at ideal germicidal wavelengths and provide reliable on-demand disinfection without the limitations which hamper mercury lamps.
How Do UVC LEDs Disinfect Pathogens? UVC energy is absorbed by nucleic acids inside the RNA and DNA, resulting in covalent bonds which at the right dose can render the pathogen unable to reproduce and infect. The most effective germicidal wavelength occurs with a peak between 260 nm to 270 nm, the point at which DNA absorbs UV energy the most.
Are UVC LEDs Effective Against COVID-19 (Coronavirus)? Crystal IS initiated a study with Boston University's National Emerging Infectious Diseases Laboratories (NEIDL) to understand how SARS-CoV-2 responds to ultraviolet light across the emission range of Klaran UVC LEDs (260 nm to 270 nm) and at varying doses. Exposing the virus to a 5 mJ/cm2 dose of UVC light at 268 nm resulted in a 2.8 log reduction of the virus.
UV-C Light Kills Viruses but That Does Not Mean You Should Use Them. Because it has the problems when Using UV C Light is Home or Office Settings: UV-C light contains radiation that is harmful to humans. Even looking at UV-C light can cause pain or damage to the cornea of the eye. Human skin can also become irritated and damaged by it.
Blacklight blue UVA 395NM led light
These are the type of ‘glow-in-the-dark’ light bulbs that most would associate with ultraviolet light. The wavelengths that these UV lamps emit are between 370–400nm, right on the border of visible light. Typical uses include:
Detecting forged bank notes
Carpet cleaning (to detect stains)
UV nail lamps
BLB light bulbs are covered by a very dark blue or purple filter, and give off a purplish glow. Fluorescent tubes – either straight or turned into more compact shapes, like the example pictured – are the most common type but there are other lamp varieties available.
When using BLB lamps with UV varnishes or paints, check the manufacturer’s guidelines on the correct lighting needed to activate their product.
While BLB light bulbs are not hazardous to your health in the same way that germicidal UVC light bulbs are, they should always be handled with care. Wear gloves when handling them to avoid contaminating the light bulb, and ensure they are disposed of safely. Avoid long exposure where possible.
Blacklight UVA 365NM LED light
Blacklight lamps are not to be confused with the blacklight blue type described above. While they still fall into the same UVA bracket on the ultraviolet spectrum, the slightly shorter wavelengths (between 350-370nm) result in very different effects.
Moth-killing lamp, light traps, led moth killing light
What is the most effective light source to attract wide range of insects to light traps?
If you are going to capture different kind of nocturnal and aerial insects to identify prey availability for insectivorous bats in agricultural lands. For that, I recommend to use light traps. What is the most effective light source for this study?
Insects can perceive light in the 300-650 nm range, but prefer light that is between 300-420 nm which includes UV light. A light’s UV output is probably the most important factor in its attractiveness to insects. Since most insects are attracted to UV light, this is why most ILTs (Insect Light Traps, including bug zappers) utilize UV/blacklight bulbs as their source of attraction. Insects generally see 3 colors of light, Ultraviolent (UV), blue and green. Common uses for these light bulbs include:
Bug zappers (the UV light attracts bugs)
They emit a mixture of ultraviolet and visible light and will appear to glow a luminous blue colour when operating.
Regular safe amounts of UVA and UVB exposure
The term black light refers to a specific kind of lamp, typically fluorescent, with a special phosphorescent coating that emits UV radiation in the UVA range. But now this fluorescent blacklights will be replaced by UV-A led lights. Regular safe amounts of UVA and UVB exposure will provide you with a regular basking bulb with a power converter. But regular fluorescent blacklights can be used safely, but BLB will damage their eyes.
UV-A 365nm, UV-A 370-375nm, UV-A 380-385nm, UV-A 390-395nm, UV-A 400-405nm, UV-A 410-415nm sky-high ultraviolet light light-emitting efficiency best for Ultraviolet curing adhesive, ultraviolet curing ink, favorable Fluorescent layer printing.
