If you are ever thinking of going solar or wind, these would be a MUST. A few years ago when I first looked at these lights, They were around $15 each and the light quality was that 'sickly' light that I hate. I tried them again 3 weeks ago. I bought a few different brands to check them out. The cheaper, Lowes, no-name lights IMHO have the best and most incandescent-like light. I didn't care as much for the phillips or GEs brands. Phillips is the only one that I saw that made dimmables however. I replaced about 30 bulbs around my house. My wife wouldn't have even known if it weren't for the slight delay on the outdoor bulbs in this cold. Man, they have come a long way with these things. 3 ways and dimmables as well. (By 3-way, I mean the 50, 100, 150 watt type) I live in a pretty dark house and so we have lights on all the time. The 60Watt CF uses 12 watts of electricity and still puts out the equal to a 60 W regular bulb. I just wired in 8 sockets in my shop but first looked at the 4 and 8 foot fluorescents. They used 2 110 w bulbs. I have 8 "60w" CFs for 112 Watts! I would have used at least 400 watts of long tube lights to get the same light output and 480w in 60w incandescents. Here's the real test........ Got my Electricity bill today after only 2 weeks of billing on the new lights. $110 less than this time last year. Wasn't colder here then either. If you look around at Lowe's or HD, you can find 6 packs of 60w equivalents for $9. Buy them as E is not going to get cheaper anytime soon. Get them while you can.
