The new fluorescent bulbs are hideous, don’t give much light and if broken are poisonous.
Someones making a killing on the new bulbs.
The conversion the packages use are 1 CFL watt = 4-5 incandescent watts, so a 15 watt CFL is listed as replacing a 60 watt incandescent. From what I've seen a 3x factor would be more accurate for real usage, so a 15 watt CFL only really matches a 45 watt incandescent and you'll need a 20 watt CFL for a 60 watt incandescent.
