The light is just right for all my rooms. They do last a long and save money. I have been using the Fluorescents for a long time and this is my first on-line order for light bulbs. Of course some of them came broken. All four corner light bulbs were broken. I didn't tell Amazon.com or expect a replacement.
Good value even with 4 broken. I recomment these to every one.

Just a little caution on CFL's in general. They are made using the element Mercury. If one of these bulbs breaks, it's going to cost you a small fortune to get the mercury cleaned out of your house. If you have small children, don't put these bulbs in any place that might be in danger of being broken. Sure they'll save you money on your light bill and the companies make you think you're saving the planet, but you're hurting it really. In 5 years, when these bulbs start to burn out, our landfills will be full of mercury. I wonder what the autism rates will be by then?

This is a great energy saver and a great package price. The light from these lights a satisfactory.

I bought the 12 pack of these bulbs and replaced every incandescent bulb I could with them. They give off a nice warm light, not harsh at all. There is a brief pause between flipping the switch and the light coming on but that's the way life is in the non-incandescent world. At least you get a warm fuzzy feeling knowing you're being a bit kinder to the environment... and you're saving money on the power bill.

No complaints here.

I recommend this product highly. It not only is cheap at Amazon but is a good quality product to gain the best energy saving advantages.

We use a lot of natural light in our home, so this 12-pack was perfect for replacing bulbs in the few fixtures that we use often. The warm white is especially wonderful in the living room and kitchen areas. I haven't noticed an 'on' delay when turning the lights on, but I do notice that there's a few-second warm up period before they brighten. The only lamp that we couldn't use these bulbs in is our 3-level dimmer lamp. My husband immediately noticed that it was "not as bright" in our hallway after we installed them, but we noticed our utility bill was a few dollars less. We freecycled our incandescent bulbs and are greatly enjoying our energy-saving lighting.

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.

Amazon offered us a great insentive to go green. I have replaced all my lightbulbs with these. After you get used to the few second delay when you turn these on then you will be very happy with the more true light they give off.

You will also love the fact that your electric bill will go down.

They come packed very well with each bulb in its own sturdy little box in a larger box and then in a big box with airbags. Arrives in perfect condition.

I grew up in the "house of dark." My parents were immigrants who also suffered through the depression so electricity and phone bills (luxuries!)were closely watched. In response I have always desired a very bright environment. I have 7 lamps and track lighting in a 12x18 living room + eating el. Maybe I didn't read closely but I somehow thought these bulbs were equivalent to 100 watts which is my absolute lowest. The basic message is that if you want to go green but maintain a high level of artifical light closely read the comparable wattage. My son and DIL have inherited "light deprivation decorating" so they will be the recipients of this order.

These 13 watt bulbs will save you a few bucks each year ,and will give you good light, but not as bright compared to a traditional 60 W bulb.. There is a slight delay when you turn them on, and they are not compatible with a dimmer. These are not the brightest CF light bulbs on the market, but are great deals for everyday uses, like placing them in the bathroom, or hallways. I would suggest using CF bulbs for places where you do not need super bright light, and will leave the light on for extended periods of time. These will save you on energy costs and help the environment.

Ordered a 12-pack and three of them were shattered when they arrived. I know that it is not Sylvania's fault but I guess buying light bulbs online is not the best idea. I got them at a store and they work great. Much better than the GE bulbs.

I bought these for my grandparents after doing my whole house with them. They love them and the startup time really isn't an issue due to the fact that they usually leave their lights on all the time.

These bulbs work well, and I personally don't think the half second or so it takes for them to light up to be an issue. However, they are certainly not bright enough for my needs, and thus I find I need to use a halogen bulb in one lamp in a room I am in while also using one of the fluorescents in another lamp. Don't know if, energywise, this is defeating the purpose or not. Another issue - 10 out of the 12 bulbs shipped were smashed on delivery(Thank you, again, Amazon, for standing by what you sell and for the partial refund). I have ordered halogens many times through Amazon, and everything arrived intact. This is my second order of fluorescents through Amazon, and both times bulbs were broken. Amazon, and its dealers, need to pack these items better. But, I am not sorry I purchased these.

These arrived a couple of days ago, none broken. Each bulb was individual boxed inside a Sylvania carton, this inside an Amazon box with 1 other item I had ordered. I was surprised there was no other packing material, the normal bubble wrap was absent. The basic Sylvania packaging seems quite adaquate for shipping.

I'm new to flourescent bulbs. Not sure if I want to use them everywhere. I ordered these primarily to experiment with replacing the lights in a bathroom vanity light bar that seems to eat normal bulbs at a high rate.

So far I'm very pleased. These bulbs are quite compact while still putting out a nice amount of light. And of course the price is hard to beat.

Purchasing these bulbs was among many things we're doing to be more energy efficient and 'green'. Even though these bulbs may not be so green. Overall, I'm please with them as a replacement. As with any fluorescent, there are some things to get used to.

1) There's definitely a color difference. You do get used to it, but it's noticeable.
2) When you turn them on, there's a short delay in getting any light and then a long delay to reach full brightness. Again, not that big of a deal, but it takes getting used to.
3) We had intentions of replace all of our incandescent bulbs with these. However, their design makes them ugly when used with exposed light fixtures. We've taken advantage of the somewhat graceful look of incandescents. With these sticking out, there somewhat ugly.
4) I love the fact that they're somewhat cooler, which makes it less dangerous when you have children.

I may not have bought the pack, if I hadn't gotten such a good deal. I'm please with the purchase and the differences are fairly easy to get used to. I would recommend for those that are interested in energy conservation and saving money!

Amazon has really disappointed with me with how they handled this transaction of mine. On ordering this set of 12 bulbs, I was shipped only 1 bulb. On registering a complaint, I was assured of the correct delivery the second time. However, for the second time too, I was shipped a single bulb! When I again registered my complaint on phone, the customer service rep was extremely rude. I was told that Amazon can not do anything as it is shipper's fault! Well, as far as I can see, this is being sold and shipped by Amazon directly. I could vouch for Amazon's good customer service before this transaction but now I can only warn you to save your time by not ordering this bulb as most likely you will also get a single bulb delivered for 20 odd bucks!

CF bulbs CANNOT be just thrown away. They MUST be treated as toxic waste. Will everyone remember? Is "Toxic" the new "Green"? No, not really. We are just trading one problem (high energy consumption) for another (toxic pollution of our watershed).

I hate working under fluorescents, and would rather live in the dark than populate my house with cold, 60Hz flickering light.

fluorescent bulbs really only take seconds to brighten up and in the wee hours of the morning, I like having a soft bathroom light, instead of a flood light effect on my eyes! A few seconds is worth helping the earth. I also use them in my light over my quilting machine and it is perfect. /they also work well in the ceiling fixtures. We are pleased with them.

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?

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.

Sure~it takes a mini second to come on~~who cares? Excellent price for a dozen~you can't go wrong and your saving on your electric bill..win/win

Arrived earlier than expected, no bulbs broken, very good price (got as one of those lightening deals), very pleased.

I like these so much I replaced every incandescent light inside, and outside, the house. The electric meter spins slower now, and I feel good. ... It was kind of interesting, after I collected the removed incandescent lights, I did not know what to do with them. ... They still worked, as energy suckers, but they still worked. ... They could be used as replacements, but that would have defeated the purpose of the changing. ... In the end, I just chucked them into the recycle bin. ...

Very good value for the money, especially with free shipping which came fast and in great condition. I thought they might break, but they did not. They are to last a long while and I am replacing most of my bulbs now

We love these bulbs and that we're helping the environment. The only "con" if you will is that it takes some time to get used to the lights taking a second to turn on after you flip the switch.

If you want the light to come on like now chances are you don't want these.Now the light takes a second to come on (not all the time,sometimes its instantaneous)and will be slightly dark til it warms up(another few seconds) and brightens the room very nicely.
So morale of the story:All good things come to those who wait.
Or if you can't wait 5 seconds for bright light you should probably learn some patience.

I have found better prices, [...]. I have installed them throughout our house and note the following:

Noticeable reduction in power bill.
Perfectly reasonable light, especially in shaded lights.
Best for areas where lights are on for more than 30'.
Not good for closets or similar "off-on" situations.
Last for a long time.
Can't be used with dimmers.
Take a few bulbs to local recycler about twice a year.

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.

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.

These work, they last forever and they use 1/4 of the energy. Buy them as gifts, take them to grandma, or your neighbor. the sooner we all have them the better. And it keeps my mom and aunt from climbing on chairs to change the old type bulbs that burn out to quickly. Thanks.
