I recently decided to switch out all the bulbs in my room to compact fluorescent. My main concern was that they would look very different from the regular yellowish light that I prefer, and that I would not get used to them. I first used a GE CF 75 watt (20 watt input) bulb to replace a secondary lamp in the room, and while it was very bright, the light was pure white, what I dislike. A week goes by, and I decide to replace my main reading lamp as well, the one that by far is on for the longest. I decided to go with a GE CF 100 watt (26 watt input) bulb instead, and boy was I pleasantly surprised. The light that came out was very similar to a regular light bulb, with that yellowish tone. It was very nice indeed. Now all three bulbs in my room are CF. Originally I was consuming 60watt + 60watt + 60watt (180 watts) for the 3 old bulbs in my room. Now it's 20watt + 26watt + 26watt (72 watts). And it's so much brigher too, individually or when you compare all 3 light bulbs on at the same time.
I highly recommend people who haven't tried CF yet to give it a try. Only thing to take note is that they require special attention when you're disposing them after their 5-8 year run, since they contain mercury.
And on the subject of going green before global warming kills us all, what else do you guys do to contribute? I recycle as much as I can, and I admit, even skip a few toilet flushes daily to save water. It's quite addictive I must say.
