![]() The benefit is that the light can be used unshielded in occupied spaces. However, there are some light fixtures that utilize UV-A for low levels of disinfection. UV-A light is not usually utilized for germicidal lighting purposes, as the exposure times to damage microbes are very high. It is still prudent to avoid long exposure times, especially if looking directly at the light. UV-A is relatively low power, longer wavelength ultraviolet light and is considered the safest of the UV spectra. They can also be used to detect organic materials like searching for evidence of bed bugs. BLB blacklights are used for special effects and inspections such as mineral analysis. The filter blocks most visible light, leaving only a faint violet glow when the bulb is turned on. Common BL Blacklight ApplicationsīLB blacklights, by contrast, are easy to spot with their dark blue filter that covers the bulb. They are used for insect traps, tanning beds, UV curing, phototherapy, and other ultraviolet applications where visible light along with the UV is not a problem. BL Blacklight BulbsīL blacklights look just like standard fluorescent light bulbs. Both of them emit the same UV-A wavelength, but one blocks out most visible light where the other does not. However, UV-A bulbs are considered ultraviolet bulbs as their peak wavelength is in the ultraviolet part of the spectrum.īlacklights have two different designations, which you can usually find at the end of the part number for a given bulb. This part of the spectrum is called UV-A, and it is just inside the boundary with visible light. Used many times for industrial processes.The fluorescent blacklight category consists of bulbs with phosphors that create a peak wavelength at 365 nanometers. Of course, there may be situations where you might use this for some kind of effect but that is not it's primary use. Once it’s lit it goes into this light purple that you characteristically see in bug zappers or bug attractants. ![]() And when this one is unlit it simply has a white phosphor appearance. ![]() We should state this isn’t the kind of black light that is used for special effects like the black light blue, that’s a completely different type of black light. It’s very simple to look on the side of the light tube itself to see which one you have and select from our list. It comes in all different sizes which vary in watts and length of the light bulb and whatever fixture that you have needs to be matched up to that length and wattage. Nearly all of it's light comes from that area of the visible spectrum which can be used for many of the tasks that we have been talking about. The 350 stands for 350 nanometer peak in the spectral range. But most of these have been used for many decades in the past and still give the exact type of lighting you need in a narrow part of the spectrum. Typically these run off a magnetic ballast or possibly an electronic ballast if you have a newer unit. If you're looking for them in a bug zapper, then the size must be exactly the same as what you use now. There are many industrial machines that use this type of bulb to spot imperfections or used in some kinds of metal or plate exposure. Black light 350 bulbs are used mostly for special exposure and bug light fixtures. ![]() B元50 blacklight lamps used in certain exposure processes are known also as 350 black lights or 350BL. ![]()
