 Not instant-on February 18, 2008

These bulbs are decent, but they do not light up instantly like some other models/brands. They take 1/2 - 1 second to come on, so they're not great for a hallway unless you would normally leave them on all of the time anyway.
The light color is very white. It's not too blue-ish or green-ish, but it's not as "soft" as the "soft white" of other brands; you won't mistake it for incandescent.
With those caveats, this is still a decent bulb. I'd buy a Sylvania CFL way before I'd buy a GE CFL.
 Not the best option February 18, 2008

I have used these bulbs a few times before and can tell you that they are horrible options for lighting.
Good:
*Save money on power
Bad:
*Poor lighting compared to incandescent, this is the same as office lighting, only you get the flickering dull light in the convenience of your own home.
*They can last about half the time as incandescents, so that money you save in power you are paying in buying new ones.
*They contain Mercury, as in the liquid metal. You are not supposed to throw these in the trash, they NEED to be taken to a recycling center to remove the mercury. I imagine most will not do this and just throw them in the trash...so now we have a ton of mercury in the ground.
*These do NOT work with dimmer switches, so if you want these to set the romantic mood in your bedroom or dining room you will just see a strobe light until it explodes.
If you really care about the environment, which is probably why you are looking at these, then keep the incandescents or look into LED lights. They use less power than fluorescents and put out a whiter light.
 Don't "Stock up" until you know what you are buying! April 22, 2008

Compact florescent(CF) bulbs are a great way to lower your energy costs,reduce heat and extend the life of your bulbs.That being said be aware that different types/brands have different Operating characteristics, some have harsh almost "Halloween" style light, some take a minute or so to warm up to full brightness, some take a split second to come on at all. Not every CF is going to meet your needs in a particular situation, so try different ones until you find the ones that say look good in the kitchen, although others might be better to read by,don't feel bad using a Halogen to read if the CF gives you a headache, and don't "Stock Up" until you have tried and like the light output.
 Headaches connected directly to fluorescent lights April 22, 2008

We thought we'd do the "green" thing by replacing all of our lightbulbs with fluorescents. I noticed that I was getting horrible headaches--the kind that just keep you from thinking. Nothing would help them at all--advil, tylenol, even prescription meds. The doctors even sent me to have a CT of the brain, but didn't find anything. After about a year (yes it took that long) I read a medical journal account on the Internet about how these can cause major headaches--so we took them out, and put the old ones back in. The headaches disappeared. Recently, one of the regular ones burned out and (unbeknownst to me) my husband replaced it with the fluorescent (it was convenient and available) and my headaches returned. When I mentioned it to him, he told me about the bulb.
I have similar headaches in warehouse stores that use fluorescent bulbs that are uncovered, but when they are covered, it seems to be better.
And of course, everyone knows that when disposing of these bulbs, you must be very careful, as the mercury levels are very high and can make you very sick if you break the bulb.
They use much more material than a regular bulb, and use up much more space in our landfills. Between that, the cost and energy used to produce them, the mercury levels and the headaches, I think these sorts of bulbs are horrible.
Yes, they last awhile longer than the regular bulbs. But at what cost?
"green is good"-with a cautionary note or two, that is... June 2, 2008

Sylvania makes these 13-watt (120-Volt) Compact Fluorescent light bulbs; and they do work pretty well! I changed over as many light fixtures as I could a few days ago; and I'm saving money on my electric bill as well as enjoying the fact that these light bulbs last much, much longer than conventional "incandescent" light bulbs.
One thing is very positive: for most lighting fixtures, you will not have to worry about the compact fluorescent light bulb fitting into the electrical bulb socket. They fit in very easily; I even compared the two metallic ends in the store to make sure they really were the same width and length! This truly manages to omit just as much light as a conventional 60 watt light bulb while only using 13 watts of energy. I'm no physicist; but the math looks good to me!
These light bulbs come in packs (you may be able to buy them individually) and just make sure that you hold onto your receipt before you install them. Every so often a bulb just won't light up all the way; I got a few that didn't light up for the very furthest "spiral" part of the bulb away from the socket. Amazon or any company will almost certainly take it back if you keep your receipt.
There is one change, however, that I will have to get used to: these bulks don't exactly function the same way incandescent bulbs do. First, when you turn on the light, the bulb will flicker for about 15 seconds before turning on all the way. Actually, this isn't too bad. The second "feature" does bother me, at least for now--the light from the bulb isn't quite the same intensity that you would get from an incandescent bulb. The light is slightly less intense; and it also might be just slightly on the yellowish side. This may be because I have frosted ceiling light fixtures in my kitchen; I am not sure. I didn't notice it so much in the hallway of my home where the new bulbs were also installed; so maybe the yellowish "color" of the light was because of the fixtures in which I used these bulbs.
Overall, these bulbs DO save money and they fit most lighting fixtures. Do NOT choose these if you have a "dimmer" feature on your lighting fixture; they make special fluorescent bulbs just for that type of lighting fixture. I predict that you will definitely save money on your electric bill; and I really like that these bulbs last for years at a time. That's incredible; most of not all incandescent bulbs would have to be replaced much, much sooner than these bulbs will need to be replaced. I recommend this light bulbs for people like me who want to go as "green" as possible.
