Health Concerns with Grow Lights?

[naoki]

UV is emitted from some fluorescent bulbs, but not a lot. https://en.wikipedia.org/wiki/Fluore...mps_and_health

White LEDs don't emit UV, but majority of white LEDs emit lots of blue light (especially the cooler white ones). Some people are concerned about the effects of blue light. Blue light influences many aspects of health because circadian rhythm can be influenced by blue light. So it might be better to avoid it at night if you are sensitive.
