Our brains on LEDs

Here's some helpful information about how our brain, eyes, and LEDs (light-emitting diodes) interact with each other.

Let's start with a bit of biology. Apparently, the human brain has a really easy time compensating for changes in color intensity but they're not so good at discerning differences in light intensity.

Birds and humans—both suffer from health problems from too much light

Did you know we have something in common with birds? And no, I'm not talking about our mutual love of trees. Both birds and humans can suffer from health problems as a result of excessive light. This isn't an issue new to this website, but I think it's important to reiterate over and over again.

Many of us want to increase the value of our property by adding beautiful lighting designs. We also want to be safe. But as this author points out, a floodlight with two 150-watt conventional bulbs can add $100 to the electricity bill every year, and in hard economic times like these, none of us needs to be wasting money like that. Smart designs are more efficient, easier on the pocketbook, and better for the environment, too.
