With SEKONIC LD, you can use the full functionality of the spectrometer C-4000. You can remotely control the C-4000 via Bluetooth and view graphs of measurement data in various way. It displays illuminance (lux or foot-candle), deviation (⊿uv), color temperature (K), color rendering index (CRI/TM-30), and CIE1931 chromaticity coordinates (x,y). and imports stored data from the C-4000.
SEKONIC LD offers upgrade option with in-app purchases (3-month subscription, 12-month subscription), including a 2-week free trial. With the upgrade, you can import drawings such as lighting layouts or site photos, and link measured values directly on them. Even if you stop the measurement midway, you can add notes to the saved data, making it convenient for multiple measurements. You can also attach smartphone images and notes to each measurement data. Location information of sites can also be attached with GPS data.
Compile project data into simple reports, output as PDFs, or export as CSVs for further processing.
