Replaced a bunch of older CFs, and these are perfect. The 60 and 75W equivalents are bright, and the omnidirectional nature and shape of these make installation in everything from lamps, to overheads lights, to desk lights work perfectly.
The only issue is that they have a distinct pattern, so if they are visible (e.g. in bathroom mirror lights, or behind soft-white ceiling fixtures), you'll see the LED structure. I actually like it, but it is visible.
