Cave Light Comparison Testing Presentation and Data Files

At the regular grotto meeting of 16 March 2021 I gave a presentation comparing various kinds of cave lights. This post has links to the presentation file and to the data files that I collected.

The data files are plain text, comma-separated values. They can be imported to any spreadsheet or graphing program. I used to create the graphs in the slide show.

The first column in the data files is elapsed time in seconds. The second column is the brightness in lux.

The file names mention the light that was tested, the battery that was used and the brightness setting.

If you have questions about any of this, let me know.
