  • An incandescent bulb uses over 4 times more electricity than the other types
  • The overall price of bulbs does not differ too much between the three different types, because of the low cost, but also short lifespan on the incandescent bulbs.
  • Overall, LED’s and CFL’s will cost 25-33% of the cost of incandescent bulbs.
