Can anyone recommend some easy ways to perform runtime and output graphs?
I know you can use a regular Lux meter and eyeball the reading every ‘x’ mins and jot it down in Excel to create a graph.
But I’m assuming there are some more modern and easier ways to do this also? Such as automatically tracking Lux over a duration and plotting it in an app.
Zak's ceilingbounce app. Focused on runtime graphs. Maybe you could use it for output as well, but never done that, so I don't know how accurate that would be.
Here is a list of Luxmeters that do the logging for you as well.
I’m using the app for all my runtimes on an old phone connected with a powerbank.
Afterwards i calculate Lumens with my Maukka light calibrated Lumen tube.
Thats fairly spot on, since the app gives percentual output as well.
