P2: Darkroom - Safe Lights, Developing Tank & Film Hangers/Holders
| |||||
| DARKROOM SAFELIGHTS, RED LEDs These darkroom red safelights are comprised of a cluster of 20 light-emitting diodes (LEDs) in the film-safe spectrum; red lights generally work well with papers which have an amber light 'prescribed'. The LED lamps are supplied in a small bulb housing and are available with the modern and safer GU10 base as well as the traditional, large Edison screw fitting, E27. These bulbs consume very little power - less than 2W - but produce light similar to a 20W incandescent bulb. Output is bright but precise at 630nm wavelength, which is ideal for TEM films, red-safe autoradiography emulsions, X-ray films and other light sensitive emulsions. LED Technology Safelight Design Cluster of 20 light emitting diodes in the film-safe red spectrum. Produces better quality images - no fogging from worn or damaged filters. Improved working conditions in darkroom. Affordable Price, Maintenance Free Fraction of the cost of alternative LED lamps and traditional darkroom illuminators, which consisted of housing, bulbs and filters. We recommend the use of two fittings or a twin fitting (available for GU10) with rotation and angle adjustments. It is best to bounce the light of a white wall or paper to avoid 'hot spots' and to achieve uniform lighting. Product Specifications The word "safe" is a relative term. Most sensitised materials will become 'fogged' if exposed to a 'safe' light for an excessive period of time. Always minimise the exposure of photographic materials to safelight illumination but aim for a brightness that makes darkroom work easy and effective. Testing a safelight: With the safelight on, lay a piece of film (emulsion up) on the workbench. Cover half of the sheet with an opaque object. Leave to expose to safelight for double the usual time required for processing the film. Then develop, fix, rinse film and check if there is any density difference between the covered and uncovered part of the negative - if there is, then the distance of the light must be increased. Unlike other light fittings, these do not expose electrical contacts when the bulb is removed. GU10 lamps have become common. However, we stock this item especially for our red LED darkroom safe lights with a GU10 base. These fittings are intended for wall or ceiling mounting with the wires entering from the underside of the fitting. It would be possible to connect a lead and plug, but then a base cover plate is required. The two lamp fittings may be tilted and they rotate almost a full circle. The fitting is 260mm long and 40mm wide. Chromate anti-rust treated and white enamel finish. P230-GU10Darkroom safelight, red LED, 230V, GU10 baseAUD35.00 stock?

| KODAK DARKROOM LED ILLUMINATORS Designed to replace conventional filtered incandescent safelights, the Illuminator is comprised of a cluster of light-emitting diodes (LEDs) in the film-safe red spectrum, arrayed on a traditional light bulb housing. Simply plug into a standard light socket. The Darkroom Illuminator is self-contained, installs in seconds and uses very little electric power. It is warranted for three years of maintenance free performance. Output is bright but precise at 660nm wavelength, which is ideal for TEM films and Autoradiography emulsions and many other light sensitive products. LED Technology Safelight Design Cluster of 20 light emitting diodes in the film-safe red spectrum. Produces better quality images - no fogging from worn or damaged filters. Better visibility in your darkroom. Less Maintenance Self-contained unit ready for immediate use. Easy to install into a standard light socket. Eliminates need to replace bulbs and filters. Affordable Price Costs less than traditional darkroom lamps, bulbs and filters required for safe lighting. Full Three Year Warranty. Product Specifications Darkroom Illumination To obtain high quality autoradiographs, you must ensure proper safelight conditions. The function of a safelight is to provide sufficient illumination in a darkroom while protecting the film from unwanted exposure. ProSciTech recommends the KODAK Darkroom Illuminator for use with Autoradiography films, Electron Micrography films, and KODAK NTB Liquid Emulsion. The word "safe" is a relative term. Most sensitised materials will become fogged if you expose them to a safelight for an extended period of time. Therefore, you should always minimise the exposure of photographic materials to safelight illumination. Testing a safelight: Expose a sheet of film in the TEM (no image) to a light grey level. Lay the sheet in darkroom under the safelight and cover half of the sheet from light. Leave to expose for a little longer than usual time the film is exposed to safelight during casette loading, unloading and developing. Then develop film, fix and rinse. Check if there is any density difference between the covered and uncovered part of the negative. Note that exposed film is more sensitive to fogging (or additional exposure) than unexposed film. Slight general fogging lowers image contrast. P230-SKodak LED darkroom illuminator, European base E27, 230VAUD226.00 stock? |
