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. 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:

Fluorescent: Comes with various lamp base sizes for regular lamp holders as well as in tube form. Reasonably power efficient with a long lifespan.

Below, we've listed several examples and situations where they could be useful. 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. Incandescant: Bulb format with your country’s lamp base to fit into any lamp base. The inside of the glass bulb is covered with a coating that filters most of the visible light and the harmless but aesthetically powerful UV light. Runs very inefficiently where most of the energy is converted to heat rather than light – an older technology replaced by LED. 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.

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

They give off a purple-coloured light, they can be used in:

The LED strips can be cut to length in 1-inch intervals, meaning you can install these in tight spaces such as photoboxes and display cabinets. Best of all, because they operate on very low voltage 12V DC, there is virtually no electrical or fire risk.Cutibacterium acnes, a bacterium involved in acne causation, exhibits an orange glow under a Wood's lamp. [20] A Wood's lamp is a diagnostic tool used in dermatology by which ultraviolet light is shone (at a wavelength of approximately 365 nanometers) onto the skin of the patient; a technician then observes any subsequent fluorescence. For example, porphyrins—associated with some skin diseases—will fluoresce pink. Though the technique for producing a source of ultraviolet light was devised by Robert Williams Wood in 1903 using " Wood's glass", it was in 1925 that the technique was used in dermatology by Margarot and Deveze for the detection of fungal infection of hair. It has many uses, both in distinguishing fluorescent conditions from other conditions and in locating the precise boundaries of the condition. A Wood's lamp may be used to rapidly assess whether an individual is suffering from ethylene glycol poisoning as a consequence of antifreeze ingestion. Manufacturers of ethylene glycol-containing antifreezes commonly add fluorescein, which causes the patient's urine to fluoresce under Wood's lamp. [21] Other [ edit ] Prevost E. (October 1983).
