I tried sleuthing for what I thought would be simple answer. But, no. Everyone’s got a different answer as to what’s equivalent and exactly how much a CFL will save you over the life of the bulb.
But with all the numbers, I discovered that the rule of thumb seems to be to look for a CFL that’s roughly 1/4 (one-fourth) the wattage of the traditional incandescent bulb you’re replacing.
Based on the information I found, the chart below should be a good estimate:
