> There would appear to be more intense blue light in an LED than coming from the sun. I was surprised at how intense LEDs are. When I got my eclipse viewing glasses [1] for viewing the 2017-08-21 eclipse I spent some time trying them out on every seemingly bright light source around my house and my office. The only things that were easily visible through the eclipse glasses were a 3500 lumen 200 watt halogen bulb, and the white LEDs from an iPhone 6 plus flashlight app, a hand cranked emergency flashlight, and an LED head lamp.
