LEDs - The Most Efficient Modern Man Made Light Source (35%)

They are now using LEDs everywhere and LEDs will replace most fluorescent lights in the future. Let's have a look what they can do.

BTW: Regardless of LED color, Cree advises users not to look directly at any LED lamp.

Here are a couple of videos.




Some LED safty factors:

"All light sources have the potential to be harmful to both the skin and the eyes through UV, blue light (410-480 nm) and IR emission. Independent photobiological testing of Cree visible light LED lamps has confrmed that the only health risk of visible light LED lamps signifcant enough to warrant advisory is viewing blue light with the eyes. LED lamps that emit blue light may be called multiple names, such as Blue, Royal Blue or Dental Blue. In addition, many white LED lamps, including Cree’s, are based on blue LED die and contain signifcant blue light content. Therefore, Cree has tested its Royal Blue, Blue and White LED lamps for eye safety.

Cree’s testing to date indicates that Royal Blue and Blue (450-485 nm dominant wavelength) LED lamps pose a higher eye safety hazard than White LED lamps. Other colors of LED lamps, such as Green or Red, do not pose a defned eye safety risk. Regardless of LED color, Cree advises users not to look directly at any LED lamp."
