UV Ultra Violet Black Light Bulb 20W B22

Product Information

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. Budget However, there are some reasons you may want to choose another wavelength. For UV LEDs, the general rule is that the shorter the wavelength, the higher the price. 395 nm UV LEDs, for example, are a common and relatively affordable option that provides decent levels of fluorescence at a more affordable price point. 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. One of the most versatile form factors is a UV LED flexible strip. The LED strip consists of many ultraviolet LEDs (365 or 395 nm) mounted on a flexible circuitboard approximately half an inch in width. 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:

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. Winter M. L.; Ellis M.

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? 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. 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.
