UV Ultra Violet Black Light Bulb 20W B22

Product Information

They emit a mixture of ultraviolet and visible light and will appear to glow a luminous blue colour when operating. Paraskevas L. R.; Halpern A. C.; Marghoob A. A. (2005).

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 Cole, Curtis; Forbes, P. Donald; Davies, Ronald E. (1986). "An Action Spectrum for UV Photocacinogenesis". Photochem Photobiol. 43 (3): 275–284. doi: 10.1111/j.1751-1097.1986.tb05605.x. PMID 3703962. S2CID 29022446.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. Morales-Trujillo M.

[ permanent dead link] These UV lamps have the shortest UV wavelengths, meaning they could be potentially harmful to human skin. Germicidal UV light bulbs are available as tubes, with the tube colour usually being transparent. They should be used by professionals and in industrial environments for: Tony Burns; Stephen Breathnach; Neil Cox; Christopher Griffiths (2010). Rook's Textbook of Dermatology.

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 ]

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. Bili light. A type of phototherapy that uses blue light with a range of 420–470 nm, used to treat neonatal jaundice.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.
