Types

• Outdoor solar Christmas lights are available in such styles as strings, bulbs, sets and ground-stake themes like Rudolph and Santa Claus. These lights can be purchased in white, multicolor and single color.
  
  

Operation

• Outdoor solar Christmas lights use light emitting diodes (LED) to illuminate. Solar lights have either solar panels or self-containing units that hold rechargeable batteries.
  
  

Weather

• Solar Christmas lights get all of their energy from the sun, so on extremely cold or rainy days the solar panels or batteries may not get enough sunlight. This will result in dim illuminations or lights that fizzle out after only a couple of hours.
  
  

Placement

• Outdoor solar Christmas lights can be placed anywhere traditional ones would be as long as the area receives at least three hours of sunlight each day.
  
  

Safety

• Solar lights are a safer option than traditional lights because there are no electrical cords to worry about and they are not likely to overheat and catch on fire.
  
  

Cost

• Outdoor solar lights cost more than electric lights but save money in the long run. LED lights have a longer lifespan and with solar lights there are no additional costs associated with electricity use.
