Figured I would start a new thread and see if the sphere gets any consistent results, the way it is. I have several lights that should work for testing. Here is a list, with the factory lumens figures. (as far as I can tell that is).

The object will to be finding if there is a "fudge number" (conversion factor), for my sphere, to correlate lux to lumens and see if it is possible to get accurate readings. Hopefully, these lights will be enough to tell me something. I have plenty of cells and am in the process of charging cells now. I will be testing early tomorrow morning and hopefully, I will have results tomorrow night.
I really didn't want to put this in the DIY section, since it may be a total fail, or totally not accurate, but I figured someone would be interested to see the aftermath. Especially the person who sent me all these lights to test.
For Batteries, I will be using:
MNKE 3500mAh - 26650
Sony 26650VT - 26650
LGDBHE21865 - 18650
Efest Purple 2500mAh 35A - 18650
Efest V2 Red 700mAh - 16340
Efest Red V2 700mAh - 14500
Eneloop First Gen - AA NiMH
For chargers, I am using the Enova ALL-80 and the Nitecore I4
Well, it's already looking real bad for the sphere. Here's a few readings and numbers figured out and it isn't pretty.

The three tests of each light on all modes confirm that the meter seems to be working correctly, but that either the placement of it, or the sphere itself is inconsistent. I really don't know what is going on, but it just isn't right, nor is it good. Those conversion factors are all over the place and it suggests that the sphere is too big for low lumen measurements or that the location of the sensor is totally wrong. I would think it's a bit of both, but I am not about to make changes to that sphere. It just isn't a good sphere. Not made right at all. Shoulda listened to others, but then again, I never do and never will, so that's life.
It is definitely going bye bye and I am never going to worry about how many lumens my lights are again. They are bright as hell or bright enough, or they aren't. Who really cares anyhow? I never really have.
“I’m never going to worry about how many lumens my lights are again.” I seem to remember
you saying something like this a few years ago about never using LiIon cells.
