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. 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. 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. Mike Phillips (2007-09-25). "Eikone.com". Eikone.com.

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.Again, ensure these ultra violet light bulbs are handled and disposed of with care. Here’s that link again with more information about the safe handling and disposal of light bulbs. Hemady, N.; Noble, C. (2007). "Photo Quiz — An infant with a hypopigmented macule".

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 a b c d e f Simpson, Robert S. (2003). Lighting Control: Technology and Applications. Taylor & Francis. p.125.

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 ]

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: 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. 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. Radiation: Ultraviolet (UV) radiation". World Health Organization. 9 March 2016.

When buying Ultraviolet light bulbs, it’s important to know which type of light bulb is the right one for your needs. 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.

These lamps are used mainly for theatrical purposes and concert displays. They are more efficient UVA producers per unit of power consumption than fluorescent tubes. 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. 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. Morales-Trujillo M. L.; Arenas R.; Arroyo S. (July 2008). "[Interdigital erythrasma: clinical, epidemiologic, and microbiologic findings]". Actas Dermosifiliogr (in Spanish). 99 (6): 469–73. doi: 10.1016/s1578-2190(08)70291-9. PMID 18558055. S2CID 22836457. [ permanent dead link]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? 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. 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.

Below, we've listed several examples and situations where they could be useful.

These are each meant for very different uses and, in the case of germicidal lights particularly, could be hazardous to your health if mixed up. With that in mind, we’ve put together a handy guide to help you determine which UV light bulb is the right one for you. Tony Burns; Stephen Breathnach; Neil Cox; Christopher Griffiths (2010).
