Hey drd,
I do not have a luxmeter unfortunately plus those readings are from a $15 DMM. So its most likely not accurate at all.
To be honest, I can't tell the difference between all 3 configurations with the naked eye. Would be much easier if I had two flashlight and shine it side by side.
I have also posted amateurish pics comparing the three on the other thread: https://budgetlightforum.com/t/-/8573
