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.<\/p>\r\n\r\n\r\n\r\n
The data files are plain text, comma-separated values. They can be imported to any spreadsheet or graphing program. I used https:\/\/labplot.kde.org\/<\/a> to create the graphs in the slide show.<\/p>\r\n\r\n\r\n\r\n The first column in the data files is elapsed time in seconds. The second column is the brightness in lux.<\/p>\r\n\r\n\r\n\r\n The file names mention the light that was tested, the battery that was used and the brightness setting.<\/p>\r\n\r\n\r\n\r\n If you have questions about any of this, let me know.<\/p>\r\n\r\n\r\n\r\n Bill Gee<\/p>\r\n\r\n\r\n\r\n https:\/\/www.kcgrotto.org\/guano\/CaveLightComparison.odp<\/a><\/p>\r\n","protected":false},"excerpt":{"rendered":" At the regular grotto meeting of 16 March 2021 I gave a presentation comparing various kinds of cave lights.
