When I first displayed my glass cyanotypes for the January review I used magnet spacers to displace the support from the wall enabling natural light to illuminate the image.
Since then I have been searching my favourite online auction site for vintage darkroom lamps to convert into light boxes. To date I have procured three lamps plus an old carbon carbide bicycle lamp found on the beach in Shapinsay, Orkney.
To make them Health and Safety compliant I have been rewiring them with two core cable. The lamp is illuminated by a bayonet type led bulb, cool white. I have used a led bulb to reduce the temperature inside the lamp so that the gelatine in the cyanotype is not compromised.
