DT Photon XL

Precision Lighting for Cultural Heritage

The DT Photon series is the only lighting designed specifically for Cultural Heritage imaging and color reproduction. They provide preservation-grade spectrally accurate color reproduction, conservation-friendly UV-filtration and operating temperature, and industrial-grade build quality and longevity.

The 38″ DT Photon XL can be used for standard photographic lighting and used with any copy stand. It can also be placed under an object such as photographic film or a watermarked manuscript in order to provide transillumination. Setting on the tabletop of any copy stand and used as the object-bearing surface; the top surface runs at 92 degrees Fahrenheit (33C), about the same as a human hand.

Made in the USA.
