I installed three of the bulbs in my home office hoping to have a really bright workspace. It seemed like an ideal environment to give them a try as the lights are rarely cycled more than once a day and while the 9 year lifespan is on an estimated 3hrs/day using these for 9hrs/day should still see a 3 year lifespan and plenty of energy savings. After three months the first bulb failed in a loud pop, I replaced it with the fourth bulb from the pack that I still had as a spare, within three days the new bulb failed along with one of the two remaining originally installed bulbs from the 4 pack. These bulbs also were also slow to warm up to full brightness when initially turned on each day.
Pros: Very Bright
Cons: Burns Out, slow to come up to full brightness
I have been using these as grow lights for several months now and I have been on the edge with them.
While they are bright, lately, with any package that I have been getting from my local HD, I have had nothing but issues with these bulbs- mainly with them burning out after only a few hours use, or having them "dim out" to which I have to turn off the lamp for 10-15 minutes and then turn it back on every couple of hours.
From November '12- Feb '13, I had basically no issues. Now in Feb '13, its seems like that is all I am getting. Yes, they are cheap- but now I am going to invest in another brand (albeit more expensive) in hopes of finding a better bulb that will actually last how long they are rated for (in number of hours used).
Bought these for my wood shop so I could see the true color of my work without having to carry it outside. Works in that regard, but they take close to 5 minutes to come up to full brightness (base up, shop heated to 70 degrees). Very, very annoying.
This is now the fourth brand of CFL I've tried in our kitchen. With out a doubt, these have been the worst. I started replacing my Longstar CFLs, as they died, with these Philips Ecosmart 23W 5000K CFL bulbs. The 1st one died after 1 day! The 2nd one lasted 14 days and the 3rd lasted 23 days. The 4th is still hanging on. These bulbs don't even last long enough to turn brown, like most other brands. They don't pop, or fizz, they just stop working. One came back to life for a day but then never came back. Please don't waste your money on these pathetic bulbs.
I love these light bulbs! Talk about a lot of "bang for your buck"! These bulbs give you a dramatically brighter light wherever you use them .... interior or exterior light fixtures. I own a fifty unit motel, and we are slowly converting all our light bulbs to these daylight bulbs. Highly recommend these bulbs!
Pros: Easy to Use, Very Bright, Easy Replacement, Easy Installation
Very poor life span, as others have said. Don't bother getting them. I've been very frustrated with the whole forced move to more "efficient" bulbs. These bulbs are expensive, do not last, and are overall worse for the environment than regular incandescent bulbs, since they have to be replaced ever more often. I don't know in what universe you would get 9 years out of one of these, but it ain't this one.
On the package it says that the bulb's life is 9.1 years (based on 3hrs/day use). I use my bulb for 9 hours every day, so the bulb is supposed to last about 3 years. Now, I'm already on my third bulb from the 4-pack bulb package that I purchased this fall. So, in reality, each bulb lasts about 2 months only.
Very high failure rate. Had 3 out of 8 that I bough fail within 3-5 months. They where used in bedrooms and a bathroom. They where not even used close to the 3 hour day at our house. They are claiming 9 years of life out at 3 hours a day on the package. My local Costco quit carrying the cool white CFL's which we have had real good luck with at an even better price than these. I bough 12 of the Phillips 60 watt equivalent and have had better luck with those...only one of the 12 has died....which still isn't great after less than 5 months, but a little better than the 100w equivalent.
works fine in over head fixture, bright white, not noisy like some, will not work in desk lamps, gets hot after 30 minutes and goes out, cools off and comes back on. had a sylvania cfl in my lamp for over a year that has worked fine, wanted a whiter light so bought these.was skeptical about buying these from other reviews, lesson learned!
I did my entire house in EcoSmart Daylight CFLs. Where I wanted the most lumens, I inserted these guys. These are fine when left on, but they take longer to reach full brightness than the others. And they're pretty tall.
Although none of the bulbs failed on install, I hear these 100-W equivalents may have a shorter lifespan than the others. If they fail, I'll replace them with the 16-Watt (65W) product. But at this point, I can not recommend this particular product.
I purchased a 4 pack, to change the 3 bulbs in the fixture that we have in living room. I chose the bulbs because of the daylight cool rating. One bulb went out after less than three hours. When I turned the fixture on the next day, I lost another one. Stay away from these bulbs! The other brand bulbs had been working fine, for sever years.
I bought three or four packs of these about 4 years ago, and the first one just failed so I'm looking to get more. I use these a lot longer than the 3 hours/day estimate the box gives, more like 8 hours/day, so the life hours estimate is fairly accurate. The difference in our electricity bill from replacing all the incandescents with CFLs was easily noticeable when we compared it to the previous year's bill.
They did seem blue when I first started using them, since I was used to warm white or soft white, but within a few days I got used to seeing everything its actual color. Now I can't stand the orangey color distortion of warm white.
The only 'con' of these is that the bulb part of a 100W CFL is larger than traditional incandescent bulbs and won't fit in every fixture - I have a desk lamp that I have to use a 75W bulb with because the 100Ws are too long and stick out the end of the lamp.
4 different brightnesses in one package even after warmup
PostedFebruary 9, 2013
No, I do not recommend this product.
Have a fixture with 3 sockets. Inserted 3 of these from the same package containing 4 bulbs and they were of 3 different brigtnesses, even after letting them warm up. Wasn't subtle, either; the brightest one looked like twice as bright as the dimmest. Turned them off, let them cool down, and moved to other sockets; the bright one is still the brightest no matter where I put it and the dimmest one is the dimmest.
IF YOU NEED "DAYLIGHT" THERAPY, due to SADNESS, I HIGHLY
I purposely purchased the 100 watt (equivalent bulb). It is the equivalent of ONLY using, a standard lightbulb of 100 watts USES 100 watts, but MOST of that "energy" we PAY for is approx. 70 HEAT of that hot bulb we've all touched.
THIS 100 Watt (equivalent to incandescent bulbs) uses ONLY 23 Watts. IT was ALWAYS "SUNNY" in my home, where *I needed it. Lord, it HELPED from day ONE on....
If you do not want as much as the 100 watt equivalent, that uses only 23 watts of ENERGY (you PAY for only the ILLUMINATION... not the HEAT of the conventional bulb 70% heat energy (approx.) and 30% of that is the Illumination.
If you choose the 75 watt equivalent, I believe it goes from 23 watts of true energy used to 16 watts of 13... look on the reference page of this type. The ONLY ones that do THIS "LOOKING and "FEELING" like SUN in your home and the EMOTIONAL benefits, which we usually need more in WINTER... GET THEM. They are EXCLUSIVELY called "DAYLIGHT" Bulbs and are the Compact Florescent... and NOT fluttering/flickering or yellowish tint. These NEWLY "engineered" bulbs go RID of those annoying things about TRYING to save energy costs.
GET RID of you (paying for the HEATING of the bulb: INCANDESCENCE. Even the HIGHEST WATT (INCANDESCENT) bulbs will NOT give you this TRUE "DAYLIGHT"
To close, I once took a nap nearing dusk. I left my light on in my kitchen (the Daylight bulb). When I awoke, I thought, "Oh, I must have only slept so briefly, it's still daylight outside".
NO it wasn't. THAT is how much is looks and FEELS just like daylight, so my INSIDE DAYS are as long as *I want them to be (Winter, Spring, Autumn, etc).
DEPRESSION or down? THESE SO HELPED ME, it is NOT a placebo effect. They FINALLY brilliantly engineered a new FORM of lighting. Those they are still compact fluorescents, they will NOT have the flicker affect some eyes detect, nor will you EVER experience AGAIN, UNFLATTERING "yellow" light HORRIFYING lighting.
You CAN use these in your bathroom while trying to look good... and you WILL see REAL colors of YOU and the REAL colors of all that are in your home.
Pros: Compact, Eco-Friendly, Very Bright, Easy Installation
