  • 13 watt- $2.95
  • 20 watt-$3.59
  • 26 watt-$4.89

 I was confused by the differece in watts at first…so here is a guide to help you choose the correct one:

Standard Bulb   CFL Bulb
40w = 10w
60w = 13w-15w
75w = 20w
100w = 26w-29w
150w = 38w-42w
250w-300w = 55w

We have converted almost our entire house to CFL’s…so looks like now is a great time to stock up!!
