I was surfing over at Slashdot today and noticed this post about compact fluorescent light bulbs. It’s kind of funny because I was thinking about blogging about them anyway.
I used to work at an environmental shop called the Daily Planet in Colorado Springs back in the early 1990′s. They’re no longer in business, but before they closed down, I bought a Siemens CFL for about $15. It’s a bit long compared to a normal light bulb, so it doesn’t fit in every lamp. Still, I have taken this light bulb with me pretty much everywhere I’ve lived since then and have used daily for hours on end. I figure it has to be at least 12 years old, which isn’t bad, especially when you consider it uses only a fraction of the electricity of an incandescent bulb.
A few years ago here in Indy, somebody left a floor lamp out near the dumpster. I looked at it and the only thing worng with it that I could see was that the bulb was broken and there was a bunch of jagged glass near the base of the bulb. I took it to my apartment and used some pliers to grab hold of what was left of the bulb and unscrewed it from the lamp. I put in a normal bulb and plugged it in, and it worked. It turned out it was a three-way lamp and the bulb I had in it was just a normal bulb. I went to the grocery store and looked at light bulbs and found they had three-way CFL bulbs. I think it was a GE. It’s been so long, I forgotten and the bulb doesn’t have any logos on it. Anyway, I bought it for around $15 and have used that a lot since.
The CFL in the floor lamp I have rigged to a timer. In the morning, it comes on about half-an-hour before I wake up and turns off sometime after I go to work. In the evening, it comes on around the time I get home from work and shuts off around 11:30. I set that as a sign I should go to bed, but I’m often up past that.
I have no complaints about the glow of the light. Both CFLs have a warm glow similar to incandescent bulbs. They both come on the instant I turn them on. Older CFLs apparently took a second or two to come on, but newer ones don’t have this problem. The only possible con I can think of is when the apartment is cool (i.e. in winter) and I turn on the light, each one will be sort of dim for several minutes until the bulb warms up. I think that probably has to do with the electronics, but once the bulbs warm up, there doesn’t appear to be a problem.
If you are in the market for some light bulbs, I recommend getting a CFL as a replacement. I think rather than changing all the bulbs out at once, it might be more economical to buy a CFL replacement once or twice a year until all the standard light bulbs are replaced.
