1)A single light blinking - This most likely causes are a bulb that is loose in the socket, a defective bulb, or a deteriorated connection inside the wall switch. Try tightening the bulb connection (it might be too hot to touch if recently on, so wait a minute before checking).
The cause of fading is due to a photochemical reaction involving UV and visible light. Research has shown (above) that 40% of fading is caused by UV rays. Another 25% of fading is due to heat, with 25% being caused by normal visible light.The remaining 10% cause of fading is from indoor artificial lighting, humidity, and poor dye anchorage. Visible light and UV radiation cause fading and a lack of moisture, especially in the cloth materials used to cover books.Electromagnetic energy is measured in nanometers (nm.) UV is present from 100-400nm, and visible light is present from 400-700nm.The energy that exists from 100-700nm is thererfore responsible for 65% of all fading.lectromagnetic energy is measured in nanometers (nm.)
