Unless there is some big action by conservatives to repeal Bush administration legislation that requires more efficient lighting, many old incandescent bulbs (or lamps) will become unavailable over the next few years. This will leave most of us having to look for alternative products to light our homes, the most common being Compact Fluorescent Lamps, a.k.a. CFLs, and Light Emitting Diodes, a.k.a. LEDs.† Somebody seriously dislikes something about both of these newer lamps, often resorting to stocking up a lifetime supply of incandescent lamps to avoid using CFLs and LEDs. But those are some short-sighted people who are prejudiced against new technology because of bad experiences, rumor, fear, or a combination of all three.
CFLs had a reasonably deserved poor reputation early in their development. They flickered, the color of the light wasnít good, they took a while to get to full power, and they couldnít dim. On top of that, there is a tiny amount of mercury in them, so there are some safety issues when they break, but trust me, you donít need a HazMat team to clean up the mess. Things in the CFL world have changed. High quality, reasonably priced lamps are available that have excellent light color and quality, donít flicker, donít need time to warm up, and are dimmable in standard fixtures. And as a benefit, they donít put out 90 percent of their energy as heat like incandescent lamps, which leads my friend, Architect Michael Klement to describe them as heaters with light as a by product.† This means that you donít pay so much extra to air condition your house in the summer when the lights are on. Look for ENERGY STAR rated CFLs, and check for the new FTC lighting facts label that tells you the efficiency and color of the lamp.† If youíre looking for something that resembles incandescent lamps, buy CFLs with a color temperature of about 2700 degrees Kelvin.† Donít worry about what it means, just know that it is a nice, warm, familiar colored light.† Oh, and the light will use about 75 percent less energy and last about 10 times longer than the old style lamp.
So, just when some of us were becoming a little more comfortable with CFLs, we now have to thing about buying LEDs instead. LEDs are electronic, solid state lighting, and weíve been looking at it for years in our clock radios, microwaves, and other equipment.† The technology has advanced far enough to provide interior lighting, although it is still evolving and not all lamps are quite ready for prime time.† People like the fact that LEDs donít have any mercury in them, so there is no fear of difficult cleanup (and they generally don’t break like a regular bulb anyway).† They last a really long time, an estimated 30,000 - 50,000 hours, compared to about 10,000 for CFLs and about 1,000 for incandescents. They are, however more expensive, although prices are coming down. LED efficiency is similar to CFLs, and getting better all the time. In terms of light quality, LEDs are getting pretty close to CFLs and incandescents but it may take some effort to find something you like the look of.
