LED cold light source (english)

LED cold light source Replace the current light source of your enlarger with a long-term stable modern LED panel light. Individual adaptation is supplied by Heiland electronic. Using LEDs with the primary colors red, green, and blue allows controlling white light for focusing, as well as controlling any color separately. Even mixed light consisting of green and blue is possible. The luminous colors are adjusted for multigrade paper and deviate at most +/-2 nanometers from the specified wavelength. Precise switching on and off is easily possible even without a shutter. Gradation and intensity can be adjusted reproducibly. An overview of the benefits: Full contrast control of gradation 00 … 5 No light drift: stable light from 0.1 seconds on guarantees reproducible enlargement No fan: enlargement without vibration, noise, or dispersion of dust No heating of the negative, which prevents focus shift Easier positioning of paper and tools for dodging due to an integrated red light Extremely exposure- effective - allows significantly shorter exposure times than halogen light Variable exposure intensity for different magnification scales Replacing lamps is no longer necessary White light facilitates focusing Even illumination up to the corners Ideal solution for archives – no thermal strain of glass-plate negatives Long-living, solid metal construction
