I wonder if someone here with suitable test equipment could run a graph on a chemical glowstick, the ordinary 12 hour kind, not a special fancy one. I'm basically hoping for a rough estimate of the lumen output and its decay over time. I did a bit of web search and got drastically varying numbers. I guess I could make an eyeball estimate, but would want to use a reflector of some kind for the ceiling bounce.
Does anyone know if reflectors like the below are still being made? Of course I can DIY one if necessary. Web search didn't find anything quickly, but it's difficult to keep the results relevant.

I'm quite dubious of chemical light in this day and age, but they come up in discussions sometimes, so I'm interested in a concrete comparison against flashlights. Thanks!
Added: I'm happy to reimburse the cost of a few glowsticks if you're up for running this test. Or it's possible that I could order some and have them sent to you (Home Despot free delivery). PM if you want this.
The merits of lightsticks versus LED's weren't part of my question. I just wanted a measurement, not purchasing advice. The idea that a single measurement is uninformative and that I really need thousands of measurements is ridiculous. It seemed like something an AI would say, but ok I guess a human could say it carelessly. If I thought a single measurement was suspect, I'd go for maybe 3 measurements. People infer all the time from way less than thousands of observations.
As for fragility, one suggested way to use a light stick is to put it at the end of a few feet of cord and swing it around in a circle, for more visibility from a distance. Most people won't want to do that with LED lights.
