C-4000 combines precision light measuring technology, renowned in the industry with the flexibility and convenience of smartphone technology. Designed specifically for the lighting designer and field technician in mind, the C-4000 Spectrometer offers a compact, lightweight, sophisticated, and affordable solution, truly the dream tool for lighting designers.
With its 2.7” color touch screen, Bluetooth® enabled wireless communication and compatibility with Apple® and AndroidTM smartphone/tablet, the C- 4000 offers the most flexible and real time on-location data sharing than any other system in the market today.
The measurement screen specializes in basic functions, and displays the values essential for light measurements, such as illuminance, color temperature, Δuv, color rendering properties (CRI, TM-30), and chromaticity coordinates (x, y), allowing you to quickly check the values on site.
With the SEKONIC LD App installed on your smart device, remote measurements are easily achieved via Bluetooth connection. The app allows you to remotely trigger measurements, view numerical values and intuitive graphs of the results, and import stored data from the C-4000 to your smart device.
