It's (probably) enough light to disrupt melatonin production in the evenings, but that doesn't imply that it's enough light to get you to produce Vitamin D etc and help with SAD during the day. Computer screens don't produce much light even compared to a normal bulb.

Good point. I forgot about Vitamin D.

But isn't that produced through exposure to UV, which LEDs don't emit?
