Function

• Polarizing filters only allow a portion of light to exit through its membrane, stopping all other light wave movements behind it. LEDs, or light emitting diodes, use electronic chips to change electricity immediately into light, producing a bright light without a large emission of heat.
  
  

Features

• If a LED is covered with a polarizing filter, the result would be a soft glow within the filter covering the entire area of the membrane with evenly placed light. Without the filter, the LED would be one small, bright spot that can produce an uncomfortable glare to the human eye.
  
  

Considerations

• By using a polarizing filter, the light from a LED can be spread more effectively to light a portion of a room, or even holiday light fixtures. The lack of heat and good energy efficiency makes the LED a good candidate for polarization in everyday lighting situations.
