How do you know which bulb to choose in terms of wattage and light output?
Use the general rule of thumb that a replacement CFL is about 25% of the wattage of an incandescent bulb. (Example: 100 watt incandescent = 23 watt CFL.) Using the chart below you can see that not only does it take a lower wattage bulb to do the same job, but you also get more savings with CFLs.
Savings estimates based on a comparison of 10 incandescent light bulbs replaced by 10 CFL bulbs.
