Recently purchased a handful of UBL12H light bars from ADJ that give direct control over the 6 LEDs in each cell (R.G.B.A.L.UV), and they supply color measurement data PDFs on their site. This data includes dominant wavelengths, output lumens and lux, wattage, peak cd, x/y color coordinates, etc.
If anyone wants to look themselves, it's the "UBL12H - Photometric Data" item in the "Downloads" section here: https://www.adj.com/ubl12h
SO! Upon exploring the "Color Configuration Field Measurement Guide" PDF and the "Relative Brightness Calculator" spreadsheet, it seems as though I really need a real spectrophotometer to collect live info to use this guide properly.
While I'd love to do the proper measurements and will try to look into how I might rent a spectrophotometer for a few days, in the meantime, is it possible to calculate relative brightness values for the Color Configuration tool from ADJ's supplied data? And what would be the best way to go about this? I'm stumbling on the "Relative Brightness" abstraction, not sure if that directly relates to the measurement data ADJ supplied.
Thank you!
