Did you end up using metal halide fittings? If yes, how did that go?
After recent research finding Opsin-5 present in multiple tissues, sensitive to ≈380nm, I’m considering options that have different emission spectra from typical LED lighting to potentially shore up gaps.

fwiw I made my account in January, which I guess is still very new relative to average age of account here but hopefully means you can trust I didn’t make this account just to drop a link to the lumina post.
Someone has posted about a personal case of vision deterioration after taking lumina and a proposed mechanism of action. I learned about lumina on lesswrong a few years back, so sharing this link.

For the past several months I have been slowly losing my vision, and I may be able to trace it back to taking the Lumina Probiotic. Or rather, one of its byproducts that isn’t listed in the advertising
I don’t know enough about this to make an informed judgement on the accuracy of the proposed mechanism.
Gradient descent generates updates by suggesting algorithmic improvements for single training examples, thereby exerting much less pressure for generality than evolution does.
A recent technique Gradient Agreement Filtering filters out gradients that disagree between samples, which if I’m understanding correctly is intentionally breaking this crux and pushing for more generalization / less memorization of specific samples.
Vague intuition that with typical LM pretraining which involves batches of far more than 1 sample + optimizers with momentum this might already not hold, non-generalizing / noisy / disagreeing updates are unimportant over the training run and the generalizing, agreeing updates stick around.
