Here is a tutorial for building a 150mm PVC lumen tube:

There’s room for improvement! What would you recommend?

Nice job and write up.
The only thing I question is how the tube might react to throwers vs floods.
I found photo grade diffusers to be really good for lumen tubes acting both as ND filters and light spreaders.

I got mine at BHPhoto.

Here is what they can do with the ultimate thrower - a laser

All the Best,

Also meant to say I sure like how you incorporated data logging of the various sensors into one build.

Thanks for sharing! The lumen tube might not handle throwers well as is.

I’ll look into different types of diffusers to put between the M-F PVC parts.
