As I said I only see that savings after getting every last one out. Places that are often missed are the porch, the garage, or the refrigerator. I have been running CF bulbs in my fridge and there are still some in the back. But this last time a bulb went out I splurged on a LED bulb for the one above the door. The funny thing is my roomate broke the glass on it but the LED's still work and now it has a very low profile.
The color on the ones I have bought recently are not very different from Irridecent once they warm up. They do take a few seconds to fully light up. So I get a more expensive ones (usually LED) for places that need light right away. The bulbs now-a-days last a long time. I usually move before I have to replace the bulbs again. Since I shop around and buy good quality bulbs on sale (usually Costco where I live) so I just leave them for the next person.
