1/7/2024 0 Comments Fluorescent black light bulbsIt 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. Neon or bright colors are more likely to have a glowing effect under the lights.The fluorescent blacklight category consists of bulbs with phosphors that create a peak wavelength at 365 nanometers. If you are using black lights for a party or other purpose, you can add fluorescent paint or clothing to make the experience more enjoyable. Other types of specialty lighting can be used for a variety of purposes. Black light lamps, on the other hand, may be used to detect contamination. However, UV lamps are deep purple or almost black in color and are more appropriate for use in certain applications, like in bug zappers. What is the difference between UV and black-light lamps?įor practical purposes, the two types of lamps are the same. LED lights: LEDs are more energy efficient than other types of lighting and can often be used in a variety of lamps, depending on the wattage.Incandescent bulbs: These bulbs are made from a UV-filter coating, such as Wood's glass, on a standard incandescent bulb.When in operation, they emit a dim, violet light. Black-light fluorescent tubes: These types of lights are made from the same materials as regular fluorescent bulbs with the exception that a phosphor that emits UVA light is used.There are three main types of black lights: What types of black-light bulbs are there? Artwork lighting: Black lights can be installed over artwork to make certain elements glow.Black lights can be used to illuminate the markings. Marking valuables: Special marks can be applied to valuables or stock items that are invisible to the naked eye.It allows for the use of invisible ink that doesn’t visibly stain the person’s hand but will show under a specialty light. Hand stamping: Theme parks, night clubs, and other businesses may use black lights to see if a person's hand has been stamped. ![]() Carpet cleaning services often use specialty light bulbs to find and treat pet stains in problem areas. ![]()
