Buy Ultraviolet Light Bulbs


The chart below shows the respective wavelengths (in nm) that different types of UV lamps produce, and where they fall on the UV spectrum. The three different types of UV light bulb available are Blacklight Blue (BLB), Blacklight (BL368), and Germicidal.

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 lamps are not to be confused with the black light 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. Common uses for these light bulbs include:


These lamps have the shortest UV wavelengths (between 200-280nm) and as a result are potentially the most harmful. Accordingly, extra care should be taken when handling and using these types of UV lights.


You can use shortwave UV light (known as UV-C or germicidal) for this purpose. However, this type of light is very dangerous and has negative health implications if used incorrectly. Please read our other guide Can I use Germicidal Lighting to Prevent Coronavirus which explains the dangers.


As germicidal UVC light is dangerous to be exposed to eyes or skin, so dangerous in fact, that I suspect any handheld UVC germicidal lamp could be fake and only contain a standard disco-type UV light source that has no germicidal properties at all. The only type of germicidal apparatus that should be used needs to be fully enclosed and allow not light to escape.


is UVC light bulb is good for sanitation and to kill for corona Viruses and any other harmful microbe element? what is the precaution before we use UVC light, because UVC germicidal lamp is already sold in the market


Hi. We have installed 12 no. UVs for a fish pond. As soon as we start up, all the bulbs are flickering at random intervals. These UVs has got electronic ballasts and there is no voltage drop as well. Can someone advise the reason. Supplier said I need to replace all the ballasts and the bulbs as both might have been damaged. Before replacing would like to know the cause.


I was thinking of making something, using UVC LEDs. What would the range of light be, to kill any pathogens? Or how close would a pathogen be by the LED before its killed?Do you sell the LED types?


Sorry Barry, that is beyond our knowledge too. However, one thing to say is that UV-C is not only dangerous to eyes, but also dangerous if exposed to skin too. We would not recommend tampering with equipment or using these light bulbs outside of a commercially manufactured fully sealed filtration or sterilisation unit.


Generally the UVC lights include a secondary element within the bulb that will make the lamp appear as a blue glow when turned on (Very obvious when lit). However you are correct in that if it was only UVC light, it would be invisible.


UVC has a wavelength of light between 200-280nm, please check the packaging or manufacturers specifications. All our germicidal light bulbs have their wavelength of light clearly marked in the product description on our product listing pages.


Ultraviolet light (UV) is invisible to the human eye. It is part of the electromagnetic spectrum that lies beyond the purple range of the visible spectrum. The ultraviolet spectrum has wavelengths between 100 and 400 nanometers (nm). The UV spectrum is further divided into wavelength ranges named UVA (blacklight), UVB (phototherapy), and UVC (germicidal).


We carry ultraviolet light bulbs using all of these wavelengths for a variety of stage/studio, special effects, phototherapy, and air/water purification equipment. If you can not find the ultraviolet bulb you need, call 800.784.1998 to speak with a lighting specialist. In most cases, we can help you locate the UV bulb you are looking for.


All of the bulbs and fixtures in this category emit light in the ultraviolet part of the spectrum. However, not all UV bulbs or fixtures are interchangeable. There are a large number of applications utilizing UV light.


The UV-A part of the ultraviolet spectrum is used in a wide variety of applications. Commonly referred to as blacklights, these UV bulbs are much more than a novelty. Although they are used in many blacklight fixtures in stage/studio applications, blacklights can be used for fraud detection of currency, validation of identification, and even identifying organic waste to track the path of bedbugs.


UV-A light provides very little disinfection power, although it can have some germicidal effectiveness over very long periods of time. It is generally not dangerous to humans, except in high dosage amounts.


Specialty UV-B bulbs are used in medical settings for treatment of jaundice, skin disorders, and other conditions. It can also be used for some germicidal applications, although it does not have nearly the effective power of UV-C lights.


UV-C light can be extremely harmful to human and animal skin and eyes, and is used for disinfection of air and surfaces, as well as water purification. Most UV-C light from the sun is filtered out before it even hits the earth.


UV-C germicidal bulbs and fixtures are most often used in medical settings to sanitize surfaces and clean rooms. Municipalities have long used UV-C for water purification. And with the increased awareness of the danger of airborne pathogens, the demand for UV-C for air purification has skyrocketed.


The most common type of UV light bulb is the low pressure mercury lamp. These resemble fluorescent tubes or compact fluorescent bulbs. For UVC, they are made of quartz with a peak transmission of 253.7nm. UVB and UVA bulbs are more similar to fluorescent tubes, using glass with various phosphors to control the wavelengths emitted. They offer the lowest cost, good energy efficiency, and long life of 9,000-17,000 hours. There are also more manufacturers making these bulbs, and more variations of the bulbs in terms of lengths, wattages, bases, and bulb shapes.


Medium pressure ultraviolet light bulbs emit broadband UVB/UVC wavelengths. These are a type of high-intensity discharge (HID) lamp. Because of the UVB component, they tend to produce more damage to enzymes of microbes and inhibit photoreactivation.


UV pulsed xenon lamps emit pulses of ultraviolet light lasting a few milliseconds. They often have very high wattages and high ultraviolet outputs. They emit a broad spectrum of light in the UV, visible, and infrared ranges. They have been found to be as effective as mercury lamps in germicidal effectiveness.


LEDs that emit ultraviolet light are currently more expensive than standard LEDs, but hold promise for applications where fluorescent tube-type lamps are inconvenient or unavailable. LEDs have a greater energy efficiency than other UV light sources and can be developed to emit radiation at various wavelengths. Blacklight LEDs are available in various sizes and bases, and some air and water disinfection fixtures that use UVC LEDs have been developed. UV LEDs have also been used to treat a range of skin disorders and wound healing.


A relatively new technology, excimer lamps emit a single wavelength. Lamps emitting wavelengths of 308nm (UVB), 222nm (UVC), and 207nm (UVC) have been developed. These ultraviolet light sources are not widely available yet, have the highest cost per bulb, and have an efficiency lower than low pressure mercury lamps.


Flying insects, such as mosquitoes, biting flies, and moths, are naturally drawn to light. Without the bulbs, flying insects are more likely to become a nuisance at any outdoor gathering. Keep your DynaTrap 1 acre models DT2020XLP working as effectively as possible with fresh, replacement bulbs. Each bulb continues to provide insect-attracting power for approximately 20,000 (around 2.25 years). Each package comes with two 2.5-watt LED bulbs to help you keep your DynaTrap Insect Trap operating to its fullest potential.


UVC lights are UV germicidal bulbs that emit very short ultraviolet wavelengths from 100 to 280 nanometers that damages the DNA of bacteria, viruses, and other pathogens. UVC light does this by damaging the nucleic acid in microorganisms so they cannot unzip for replication. This means the organism cannot reproduce and will die. The kill rate of UVC light depends on the specific microorganism you are trying to combat as well as the dosage it receives from the lamp. Dosage is a combination of exposure time and intensity (microwatts per square centimeter). Be sure you know how much ultraviolet light you need before selecting a specific lamp. If you need assistance, feel free to contact our support staff.


These lamps can help eradicate harmful bacteria and are used for a variety of things, namely in the purification of food, water and air. Because germicidal light bulbs are intended to rid an area of microorganisms, it is essential that the bulbs have regularly scheduled cleaning and are replaced annually to guarantee efficiency. Always wear rubber gloves when cleaning the lamps to protect your hands and keep your skin's natural oils off the lamps and use alcohol only. This will help maximize the lamp's life.


Available in an assortment of options, such as 2-pin, 4-pin, screw-in, linear bi-pin, and plug-in compact, you'll find the right UV light bulb for your application. Many of these lights work in conjunction with specially-designed ballasts that control the electric current flowing to the bulb. For help finding everything you need to disinfect any location, give us a call at 1-800-624-4488 to speak to a lighting expert.


Here you will find our selection of replacement Ultra-violet (UV) light bulbs. Please be certain of the model and brand of your UV light kit. UV lights provide protection from germs and bacteria build up on your evaporator coils of your air conditioning unit. Ultra violet lights treat the smaller particles that get through your filter and reach the cooling coils. 041b061a72
