Zoinks its me Dr. Z!

So you want to change out those old incandescent bulbs for hi tech Compact Fluorescent and have no idea where to start? You probably know by now that CFL’s are 4-6 times more efficient than incandescent lightbulbs, which means a 13 watt cfl can replace a 60 watt incandescent. (Remember CFl’s give you more light per watt than an incandescent.) So to make things simple I have included a simple little chart below that will help you in finding the CFL you need.

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

Hope this helps!
