Grâce à au site Svetila.com, j'ai pu me procurer ce petit transfo 12v afin de l'intégrer dans un luminaire ! Quasi introuvable ailleurs !...

UV lamp for technical applications: Sunlight simulation, glue curing, artificial material aging, exposure of UV-sensitive photoresist coatings, terrariums, equine solaria.
UV light, short for Ultraviolet Light, is a type of light energy making up one part of the electromagnetic spectrum, which spectrum includes gamma and x-rays, UV light, visible light, infrared rays, microwaves, and radio waves, listed in order of decreasing frequency and increasing wavelength. UV light thus has a wavelength shorter than that of visible light, and can not be detected by the human eye. While UV light itself is invisible, it causes many substances to glow or fluoresce in a variety of colors visible to the human eye. This ability to make the invisible visible makes UV lamps valuable for mineral prospecting, criminal investigations, postal stamp evaluation, etc. UV light is divided, at a minimum, into both Shortwave and Longwave radiation. Shortwave UV is produced by low pressure mercury arcs, with a wavelength of 254 nanometers, while Longwave, produced by low to high pressure mercury arcs, has a wavelength of from 320 to 400 nanometers. A nanometer is a unit of length used to define wavelengths of energies in the electromagnetic spectrum, equaling one millionth of a millimeter. While Longwave UV, sometimes referred to as blacklight, is safe, Shortwave UV can irritate the eyes and burn the skin, so exposure should be controlled and ideally, UV goggles should be worn to prevent eye damage from inadvertently looking at the light source.
UV lamps typically come in both portable models and as permanent display units, offering one or more wavelengths depending on the model. The basic elements of a UV lamp include the power source, the ultraviolet light bulb, and the filter. UV light bulbs are constructed of a special high silica glass, or of quartz in the finest quality. They are rated by wattage, not unlike a bulb in your house lamp, so this can be an indication of your lamp's brightness. However, this is not a hard and fast rule because the way in which a UV lamp is powered and designed also affects its brightness. Shortwave bulbs appear clear when off. Longwave bulbs, having phosphors on the inside, with or without integral filters, appear white or black (blacklight) when turned off. Along with ultraviolet light, all UV lamps emit some visible light, too, which tends to mask any fluorescence, so special dark purple glass filters are placed over the bulb to block the visible light, while allowing as much UV light to still pass through. Longwave filters, which have a relatively coarse surface appearance, last indefinitely. Keep in mind that the darker your surrounds, the easier it will be to observe the effects of fluorescence from your UV lamp. Depending upon how bright your lamp is, you may or may not be able to use it in the daylight.
Ultraviolet lights have many uses:
ACTINIC lamps are used for electronic insect killer systems, photopolymerization, reprography, dentistry and in cosmetic. With an optimized performance to attract most insects, Actinic BL TL, BL TLD and BL T5 lamps are the ideal choice for electronic insect killer systems. They are also suitable for photopolymerization and reprographic processes. A wide choice of wattages and a special 200-degree internal reflector version are available. In addition, Philips provides single-ended compact and T5 Actinic lamp versions as well as a circular Actinic lamp. For extra safety, there is a special...

Detection and analysis in the textile and chemical industries Archaeology Banking Forensic science Food industry Medicine Mineralogy Philately Special effects in night clubs, discos and theatres Sign lighting
Offset print HPA-R UVA light bulbs - ideal for reprography and photochemical processes Optimized for the UVA bandwidth (315 to 380nm), HPA-R UVA lamps are ideal for a wide range of reprography and photochemical process applications. Their high radiant efficiency and high arc-stability ensure cost-efficient and reliable usage. They provide the ideal light source for contact copying of images from transparent film to UV-sensitive carriers such as film, offset plates, printed circuit boards and microfilms. These lamps are also perfectly suitable of photochemical process applications such as...
Phototherapy lamps for the treatment of Psoriasis, Vitiligo, Hyperbilirubinemia and other skin diseases. Phototherapy involves subjecting the skin to waves of ultraviolet light. There are three types of ultraviolet light, UVA, UVB and UVC. There are treatments available using UVB light, lasers or UVA light combined with a medication called Psoralen (PUVA).Conventional Broadband UVB lamps emit light in a broad spectrum that includes both the therapeutic wavelengths specific to the treatment of skin diseases plus the shorter wavelengths which can result for sunburn. Sunburn has a negative...
High-energy UV-C Germicidal lamps for sterilization and disinfection. Effective and non-chemical. Radiation for sterilization requires light sources that are particularly powerful, yet kind to the environment. High-energy UV-C lamps provide the perfect solution here. The UV-C radiation moves at a wavelength range between 200 nanometers (nm) and 280 nanometers. This gives the radiation a cell-destroying effect that is ideal for highly effective sterilization of water, air and surfaces and eliminates the need for chemical products. UV-C radiation is used in a wide range of different...
Professional lamps for tanning beds and sun loungers, and light medical therapies. (treated skin, regulation of neurovegetative system, activation of vitamin D formation, regulation of blood calcium, dermatology)
