UV Ultra Violet Black Light Bulb 20W B22

Product Information

A short light bulb is okay for bodypaint and small parties. But if you need a light for something else, like a hall or outside, the range needs to be higher than normal. Brightness The intensity of the light should be about average. It should not be higher than normal like a flashlight. LED It is often referred to as ultraviolet ‘light,’ but UV is a type of electromagnetic radiation with wavelengths shorter than visible light and longer than X-rays. The type of UV radiation these light bulbs emit targets the DNA of microorganisms, causing cell death or making reproduction impossible. They’re certainly not the type of light bulbs to be used in the home. They’re mainly used in professional and industrial environments in processes such as: If a product lists the amount of UV light output in watts, you can use this value directly to estimate your UV light needs for a space. If not, you may have to use some rough efficiency estimates.

The revolution of LED has successfully been applied to this incredible lighting effect, creating a higher wavelength of around the 400nm range. LED has a very long lifespan and should be your first choice wherever possible. BudgetThese lamps are used mainly for theatrical purposes and concert displays. They are more efficient UVA producers per unit of power consumption than fluorescent tubes. Hemady, N.; Noble, C. (2007). "Photo Quiz — An infant with a hypopigmented macule". Am Fam Physician. 75 (7): 1053–4. PMID 17427621. Archived from the original on 2008-08-28. Most wall washers come in 2 to 4 ft lengths, and are designed to be mounted into the floor. The lamp itself can be adjusted so that the UV light energy can be directed at the specific angles required.

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. Fluorescent materials are also very widely used in numerous applications in molecular biology, often as "tags" which bind themselves to a substance of interest (for example, DNA), so allowing their visualization. Finally, when choosing a UV light fixture, you should know that they can come in a variety of shapes and forms. Below, we've listed several examples and situations where they could be useful. Winter M. L.; Ellis M. D.; Snodgrass W. R. (June 1990). "Urine fluorescence using a Wood's lamp to detect the antifreeze additive sodium fluorescein: a qualitative adjunctive test in suspected ethylene glycol ingestions". Ann Emerg Med. 19 (6): 663–7. doi: 10.1016/S0196-0644(05)82472-2. PMID 2344083. UV light can be used to harden particular glues, resins and inks by causing a photochemical reaction inside those substances. This process of hardening is called ‘curing’. UV curing is adaptable to printing, coating, decorating, stereolithography, and in the assembly of a variety of products and materials. In comparison to other technologies, curing with UV energy may be considered a low-temperature process, a high-speed process, and is a solventless process, as cure occurs via direct polymerization rather than by evaporation. Originally introduced in the 1960s, this technology has streamlined and increased automation in many industries in the manufacturing sector. A primary advantage of curing with ultraviolet light is the speed at which a material can be processed. Speeding up the curing or drying step in a process can reduce flaws and errors by decreasing time that an ink or coating spends wet. This can increase the quality of a finished item, and potentially allow for greater consistency. Another benefit to decreasing manufacturing time is that less space needs to be devoted to storing items which can not be used until the drying step is finished.

One of the innovations for night and all-weather flying used by the US, UK, Japan and Germany during World War II was the use of UV interior lighting to illuminate the instrument panel, giving a safer alternative to the radium-painted instrument faces and pointers, and an intensity that could be varied easily and without visible illumination that would give away an aircraft's position. This went so far as to include the printing of charts that were marked in UV-fluorescent inks, and the provision of UV-visible pencils and slide rules such as the E6B. For most basic applications, 1 watt of UV light energy output is sufficient to create strong fluorescence effects over a 100 sq ft area. For a 200 sq ft area, simply multiply the target UV levels by 2x for an estimated 2 watts of UV light energy needed. Have you ever been to a night club, halloween party, or disco and been amazed by how the white colors of people’s clothing stands out looking incredible – unnatural even? We first note that the UV output for the product is 0.9 watts per foot. Based on our estimated UV light needs of 1 W per 100 sqft, we determine that we will need 2 W for our 200 sqft area (multiply by 2x). 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.

4) What Type of UV Light Fixtures Should I Use?

Because UV energy has unique interactions with many different materials, UV curing allows for the creation of products with characteristics not achievable via other means. This has led to UV curing becoming fundamental in many fields of manufacturing and technology, where changes in strength, hardness, durability, chemical resistance, and many other properties are required. IMPORTANT: electrical watts does not equal UV light watts! As with regular household light bulbs (e.g. 60 Watts), we are most accustomed to describing UV light bulb power in terms of its electrical energy consumption. But as is the case with household light bulbs, what matters most is the amount of light energy produced. Wear protective clothing when handling germicidal UVC lamps and keep them away from your skin and eyes. It is best to avoid prolonged exposure to the light when it is in operation.

All electromagnetic waves are measured in metres, but some wavelengths (like UV) are so small that they’re measured in nanometres (nm). You will often see product descriptions on Lightbulbs Direct reference the ‘nm’ range of the lamp because it directly affects what type of light bulb it is.

Wood's lamp is useful in diagnosing conditions such as tuberous sclerosis [22] and erythrasma (caused by Corynebacterium minutissimum, see above). [23] Additionally, detection of porphyria cutanea tarda can sometimes be made when urine turns pink upon illumination with Wood's lamp. [24] Wood's lamps have also been used to differentiate hypopigmentation from depigmentation such as with vitiligo. A vitiligo patient's skin will appear yellow-green or blue under the Wood's lamp. [ citation needed] Its use in detecting melanoma has been reported. [25] See also [ edit ] Cutibacterium acnes, a bacterium involved in acne causation, exhibits an orange glow under a Wood's lamp. [20] 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. Stachel, Shawn (1999).

Best of all, because they operate on very low voltage 12V DC, there is virtually no electrical or fire risk.
