Rapid Assessment of Lamp Spectrum to Quantify Ecological Effects of Light at Night

Data and runtime for Longcore et al. "Rapid Assessment of Lamp Spectrum to Quantify Ecological Effects of Light at Night"

Demo at https://fluxometer.com/ecological/

We have provided here (in .CSV form) a list of SPDs and action spectra used in making the graphs for the above paper. Also provided is a simple Javascript runtime for calculating and graphing responses in the browser.

Things you can do:

• Review calc.js if you want to reproduce our calculations
• Clone this repository and add your own lamps to SPD.csv
• Load "index.html" using any static webserver (local files do not work anymore due to browser security changes)

The CSVs are organized as follows:

• ActionSpectra.csv: All action spectra (or response curves) used, converted to power units (not quantal)
• SPD.csv: All SPDs used
• visual.csv: Pre-computed data per lamp, including CRI, CCT, and sRGB-equivalent color
