I have a UltraFire WF-606A Q5 and I like it very much because it is much brighter than any of my other flashlight. But, I'm a little concerned about my eyes. In the datasheet for the XR-E Q5 Cree says
"Users should be cautioned not to stare at the light of this LED product. The bright light can damage the eye."
What exactly is dangerous? Of course, I don't stare directly into the LED but could ordinary use of the flashlight be dangerous for the my eyes? Why can the CREE LEDs be dangerous? Is it just the brightness of the light or does the light contain UV or IR?
