Light cant be the reason imo tempering happens. None of the tempered people we see behave like the people soon turning into sin eaters. A lot of the tempered people are active while those affected by Light are barely even able to move. Just look at Zodiark and him being seemingly Darkness. Why should he temper by using Light? Also over all the time unlike the people with Light they did not turn into outright mindless monsters. Heck only those that get too much tempered turn into strange beings, most of the others are still the same just with the believe to serve their new master.
So either the other elementals like water and fire can do the same thing too or all of those that temper somehow also use Light but unlike on the first people wont just turn into nasty monsters over time...which kinda would point against Light being the one that does it..
I wonder if maybe they just brought that up and later when Alisaie tries it out on the source they will find out that its not the same. Or maybe they find out that Ga Bu is the only that can be saved that way because he is a special case.
About that...
I believe Tempering is actually in fact Aetherical Corruption, with their aether being corrupted due to an element throwing off the natural aetherical balance their body has. In the case of Ifrit, Titan, and Garuda, it would make sense if their tempered have had their aetherical balance thrown too much towards Fire, Earth, and Wind respectively. Meaning just like with those corrupted by the Light and nearing Sin Eater transformation, they've been corrupted by a specific element, albeit not to the degree of transforming into a minion. We've seen moments of transformation due to aether corruption however, some of which besides the Sin Eaters being the Heretics turning into dragons in ARR and HW. Aetherical corruption may in fact be the cause of tempering, and now knowing that strengthening the other elements may in fact fix the problem, it could also lead to fixing the tempered by fixing their corrupted Aether.
This could also explain why Ysayle could turn into Shiva while still staying in control, as those with the Echo have already been blessed by Hydaelyn, and thus have quite a bit of tolerance to aether corruption. However, as shown by the bad future with the WoL's death by their Aether loss and the near Sin Eater transformation at the end of ShB, there IS a limit to this protection.
