Just 1 minute of red light is effective

We show that Imidacloprid undermines bumblebee respiration and immunocompetence and that this can be rescued by 670nm exposures of 1min. This positive impact lasts for 4–6 days in both cases and implies that respiration and immunocompetence have common underlying mechanisms that likely resides with mitochondrial integrity.

0.5 mins exposure had no impact. In healthy bumblebees, 1 min exposure increased respiration significantly, but longer times did not result in a further increase (Fig 1B and 1C).
Elevated respiration from single exposures in healthy bees lasted 144h

1 minute of 40 mw/cm2 intensity

Co2 production higher than controls too

And its BEES so another in mammals https://pubmed.ncbi.nlm.nih.gov/26426815/

4 minutes a day stopped the increased immune cell killing of their endothelial cells in diabetic mice

Ray said just a couple minutes, or a quick flash, is enough to help stimulate mitochondria and quench excited electrons that are out of their proper flow

Just shining red light through their head. It restores their mitochondrial oxidation very quickly. - And then it'll continue on its own for a bit without the light? - Yeah, it has a certain momentum before the stress knocks it out again. So about every 10 or 15 minutes having a little flash of light on your body would probably help

Here the momentum lasted 2 hours in humans, stimulates glucose usage / co2 production from 15 mins

If you shine just a burst of red light it quenches excited electrons , puts electrons back in the proper arrangement

Within the first hour after exposing frogs to that same intensity of gamma rays, if they shined bright red light on them, they didn't get sick at all.

Yes, the right time is fine but too long is counter-productive, not as said in the first link given.
And do not make wrong spare-money when buying the red light.

@cs3000 - Even less than just one minute would be one minute every third day.

In the 1st paper that you hotlinked Glen Jeffery, University College London was the last named author. I the first 6 minutes of this video below he speaks about the every third day. I seem to recall from a different video that every 5 days is sufficient to keep the mitos. charged.

Edit - The red light works best in the morning.

Does anyone know how much the time would be affected by a 660nm light, versus a 670nm?
