Description
 
LED lights are the new preferred form of lighting, since they are more energy efficient and contain none of the mercury of toxic fluorescents. However, they have their own "dark side." A Harvard study shows that exposure to blue light (emitted by almost all LEDs), especially at night, can be harmful to health. LED blue light suppresses melatonin. Flickering can cause tiredness, headaches and impaired visual performance, or in more serious cases, seizures and epilepsy. LEDs contain lead, arsenic and other potentially dangerous substances. Learn why incandescents may still be the best type of light. 51-min. DVD
