Kaiser Lighting Unit for Wolfenbüttel Book Reflector 45N - Fotospeed
Kaiser Lighting Unit for Wolfenbüttel Book Reflector 45N
The Kaiser K5781 Lighting Unit for the Wolfenbüttel Book Reflector 45N is a professional daylight LED illumination system designed for precise and consistent book reproduction, document digitisation and photographic imaging. Featuring 272 specially selected white SMD LEDs, a 5600 K colour temperature and an excellent colour rendering index of CRI 96, it provides soft, even and flicker-free illumination across the page being reproduced. Integrated thermal management maintains stable brightness and colour temperature, while precise dimming from 10% to 100% in 1% increments, an illuminated information display and adjustable mounting system make the K5781 an ideal lighting solution for demanding archival and reproduction applications.
Professional LED Lighting for Book Reproduction
Kaiser K5781 Lighting Unit for Wolfenbüttel Book Reflector 45N
Engineered for accurate and repeatable image capture, the Kaiser K5781 provides exceptionally consistent daylight illumination for the Wolfenbüttel Book Reflector 45N. Its large LED lighting surface, high colour accuracy and sophisticated thermal management system help maintain dependable lighting conditions throughout demanding book digitisation and reproduction workflows.
272 daylight LEDs
Specially selected SMD LEDs deliver soft, even 5600 K illumination with CRI 96 for accurate photographic reproduction.
Thermal management
Sensor-controlled compensation and passive cooling maintain consistent brightness and colour temperature.
Precise 1% dimming
Adjust light intensity from 10% to 100% in 1% steps, with an illuminated display and brightness memory function.
Flexible positioning
A swivelling, sliding and height-adjustable lamp with a tilting vertical arm and strong aluminium clamp base.
Precision illumination for archival imaging
Consistent lighting for accurate book reproduction
The Kaiser K5781 Lighting Unit is specifically designed for use with the Kaiser K5780 Wolfenbüttel Book Reflector 45N, providing soft, uniform daylight illumination for photographing and digitising book pages. Its elongated lighting panel incorporates 272 specially selected white SMD LEDs, producing a consistent 5600 K colour temperature with a colour rendering index of CRI 96. The generous 58 x 16.5 cm light-emitting area and wide 100-degree radiation angle help distribute illumination evenly across the page being reproduced, while the detachable soft screen further diffuses the light to reduce harsh shadows and uneven illumination.
A key feature of the K5781 is its integrated thermal management system, designed to maintain consistent brightness and colour temperature regardless of changes in ambient or operating temperature. During extended use, LEDs naturally generate heat, which can otherwise cause small changes in light output and colour characteristics. Kaiser addresses this through sensor-controlled temperature monitoring with dynamic compensation, combined with effective passive cooling through the LED board and aluminium housing. This sophisticated approach supports repeatable imaging conditions, making the K5781 particularly valuable for systematic book digitisation, archival reproduction and other applications where consistency between successive images is essential.
The lighting unit offers precise brightness adjustment from 10% to 100% in individual 1% increments, with an illuminated information screen for convenient operation. A memory function automatically restores the previously selected brightness level when the unit is switched on again, helping streamline repeated shooting sessions. The sturdy anodised aluminium lamp housing can be swivelled, shifted and adjusted in height, while the 142 cm vertical arm incorporates a tilting detent joint for flexible positioning. A strong cast aluminium clamp base accommodates mounting surfaces up to 55 mm thick, and the supplied mains adapter provides reliable power for continuous studio operation.
Ideal for
Professional reproduction and digitisation
- -Book and bound-volume digitisation
- -Libraries, archives and museums
