I’ve read that UV-A and red/infrared light don’t mute melatonin production.. do you think a red led flashlight would be advisable to use at night?

- Nomentatus 9y agoipRGCs are very sensitive to UV, and kill melatonin production; so I'd love to see a source. Red LED light is fine - as long as you aren't subject to seizures. But most people with seizures have them at night and are never diagnosed. LEDs flicker imperceptibly.
