Samsung has released a LED designed to minimize Melanopic Ratio, that is - to minimize its awakening effect.
It’s a 6V mid power LED so not very easy to use in flashlights but could see some use in lanterns and maybe nightstand lights.
Idea:
A lantern with Melatonin Ratio ramping. While the party is on, keep it high. On the closing, make it lower.
Though the difference ain’t huge. Samsung MR-maximizing emitters have the ratio about 50% higher than MR-minimizing ones (at the same CCT).
Lowering tint and reducing brightness has much better effect and doesn’t require sacrificing CRI…
