The Negative Supply 4x5 Light Source Basic MK2 (99 CRI) is a reliable, high-accuracy light source designed for scanning 35mm, 120, and 4x5 film. Its precise color rendering and even illumination make it suitable for both color and black-and-white scanning. With improved brightness, heat management, and compatibility with Negative Supply accessories, it is an efficient tool for photographers and film scanners of all skill levels.
Even Illumination
The Light Source Basic MK2 delivers uniform brightness across the entire film area, preventing light falloff when scanning 4x5 film. This ensures consistent results and accurate image reproduction across large-format scans.
High Color Accuracy
Optimized for color film scanning, the 99 CRI output provides precise color representation. The TLCI value, averaged from the MacBeth 24 Color Checker Chart, maintains color fidelity for critical scanning work over long sessions.
Increased Brightness
This model is over 2 stops brighter than the previous generation. The improved internal acrylic element boosts overall light output, making scans faster and more reliable without sacrificing accuracy.
Film Compatibility
Designed to work with 35mm, 120, and 4x5 films, the Light Source Basic MK2 accommodates adapter plates for film carriers and can be used to mask light from below the film plane.
Compact and Durable Design
The custom-designed internal acrylic panel, combined with a compact and heat-dissipating form factor, ensures long scanning sessions without overheating. The carbon composite construction adds rigidity and durability.
Accessory Compatibility
Fully compatible with all Negative Supply accessories for the 4x5 Light Source Basic, it includes a multivoltage AC adapter for flexible use in different environments.
