Banish the Blue LED

Someone has discovered another reason to ban the blue LED:

In a study involving hamsters, researchers found that blue light had the worst effects on mood-related measures, followed closely by white light. (Via.)

I’m glad the blue LED was finally invented, and I’m sure my life is better for it in countless ways. But that doesn’t mean it has to be slapped onto every gadget in my house. I’ve got a USB charger that I have to keep in the basement, because it has the brightest single LED (blue of course) I’ve ever seen, and if I use it in the bedroom, or even in the hallway, it affects my sleep.
