Are name-brand low-energy fluorescent "Green" bulbs any brighter thanstore brand?
Just got a 4-pack of the Walmart "Great Value" version of these energy-
saver style fluorescent 23w bulbs which they claim are equivalent to a 100w incandescent bulb. Not even close. It's about like a 40w bulb. Are the name brand bulbs of this type any better? |

It's about like a 40w bulb. Are the name brand bulbs of this type any better? A 23 watt CFL lamp should put out a great deal of light. One thing I have found when dealing with a number of CFL lights is the fact that the lamps have a warm up period. The colder the ambient temperature the more time it takes the darn things to reach full brightness. I've installed them in the bathroom exhaust fan/light fixtures at several business because of the long life of the lights and soon discovered that in the wintertime it's like a 40 watt incandescent until about 10 minutes later when it's as bright or brighter than a 100 watt standard bulb. In the summertime, flip the switch and it as bright as ever. I imagine that the more expensive CFL lamps will perform better over a wider temperature range. TDD |

I like that "feature" in the bathroom, because the light doesn't blind me as badly when I turn it on at night... |

It takes some adjustment, but after a few weeks, you'll probably no longer even notice. |

When we built out house my wife had them put in special switches that slowly raise the light level because she hates being blinded. When we started switching to CFLs on other lights we hardly noticed. Some brands are much quicker than others, too. And some lines within a brand. Unfortunately no one puts "full brightness in 47 seconds!" on the packages. |

I don't remember the brand name though, nor did I buy any, as most of the fixtures in my house already have CFLs in them and those that don't are a) rarely used and b) slated for replacement anyway. nate -- replace "roosters" with "cox" to reply. http://members.cox.net/njnagel |

There is a general trend for ones with outer bulbs to start dimmer and take more time to warm up than ones with bare tubing. Ones with outer bulbs have their tubing designed to work best at the higher temperature that occurs inside the bulb-enclosed ones. - Don Klipstein ) |

The trade off is that you have to wait a minute for the full light to come on. If it bothers you that much, get rid of them. Problem solved.

wrote: So, the problem is easily solved. Buy incandescents Better move quickly. The "Energy Independence and Security Act of 2007" applies performance standards to incandescent bulbs which supposedly will effectively ban them in a few years. I've tried to read it but it consists mainly of a lot of edits to existing regulations, like this: (1) DEFINITION OF GENERAL SERVICE INCANDESCENT LAMP- Section 321(30) of the Energy Policy and Conservation Act (42 U.S.C. 6291(30)) is amended-- (A) by striking subparagraph (D) and inserting the following: bla bla bla ... so it's not clear to me exactly what's going on. Still, there's the "Light Bulb Freedom of Choice Act", H.R.5616, which claims to "repeal of the phase out of incandescent light bulbs." -- Bert Hyman St. Paul, MN |

It's about like a 40w bulb. Are the name brand bulbs of this type any better? I have noticed that some new CFLs will take 5+ minutes to reach proper brightness on the first run even at room temperature. After this first burn in, they come up to brightness normally (within 30 seconds or so) after turning on from a cold start. The first time it happened to me I though the bulb was bad, but the ones that did that have been fine ever since. In a cold environment, they will be slower to warm up. |

In a 72 degree house it takes less then a minute to warm up. For my 100w equal I use the Sylvania CFL23EL Micromini 3000k. Works great for me. Chris |

A typical 100W incandescent is around 1600-1700 lumens. Walmart doesn't seem to give the lumen ratings on theirs but a Sylvania CF23EL is indeed rated for 1600 lumens. It may take it a few minutes to reach full brightness. But it seems like all the companies cheat on the "equivalent to" rating, if they say "equivalent to 100W" I figure it should be a bit brighter than a 60W. Dave |

I would not take lumen claims on the package as gospel truth. I have had some fall significantly short, notably many Lights of America and MaxLite models that I tested, and in my experience every dollar store unit of a "dollar store brand" whose package made a claim of light output in lumens. Ones of "Big 3" brands (Philips, GE and Sylvania) and ones with the Energy Star logo are more likely to be truthful with claims of light output in lumens. I have also found N:Vision (a brand pushed by Home Depot) to be truthful with light output claims in lumens. My experience is similarly good with the brand available in CVS stores. I would expect the brand pushed by Lowes to be similarly good in meeting claims of light output in lumens. - Don Klipstein ) |

Philips, GE and Sylvania 23 watt ones as well as those other brands prevalent in home centers (such as N:Vision) generally achieve 1600 lumens after warming up for a minute or two. Higher color temperature versions achieve closer to 1500 lumens. 1600 lumens is close to the output of a "double life" 100 watt incandescent. A "full blast" 100W 120V incandescent achieves 1670-1750 lumens. I like to think of 23 watt CFLs as being about halfway between a 75 watt and a 100 watt "standard" incandescent (750 hours) in "real-world" light output. - Don Klipstein ) |

If its not bright as 100w incandesant return it, Popular Mechanics rated them years ago, its still online but hard to find, I think in the Home section, Consumer reports did a test. I use HD soft white, I get a 9w that equals 40w for about 1$. The HD bulbs rated Better than incandesant for color at Pop mech, such as how it colors your skin. I have 60 in use and failure after 1.5 years with many in commercial use is maybe 2. Heat is what kills the ballast, as long as they are not sealed in an enclosure they last. |

Cut them off the browser address box and paste them into the post. That doesnt always work, particularly with sites that have a session id but it does work for many sites. |

If yiou get a good daily dose of sunlight, or incandescent bulb light, then florescent or LED wont have as much of a detrimental effect on your health... for offices I recommend a small incandescent light on the dest kept lit ..it supplies the full spectrum you need. in a home an incandescent near your tv watching chair would have a similar effect... I dont think the wattage is crucial, 20 watts might be fine. Phil scott |

My sensation is hype. I have studied this area enough to be in a good position to know every known and reasonably-theorized photoreceptor and significant photochemical mechanism in the human body. They a 1. The red, green and blue cones in the retina of the eye: Having 2 different light sources matching each other in color and visually-apparent brightness is sufficient to achieve matching stimulation of all 3 of those different photoreceptors by such 2 different light sources in question. Even if one is an incandescent and the other is a CFL with the usual spiky spectrum. 2. Rods in the retina of the eye: If 2 light sources have the same apparent brightness and same "s/p ratio" (scotopic/photopic), then they stimulate the rods of the eye equally. CFLs of incandescent-like color tend to have s/p ratio about 10% less than incandescents of same color. I don't think that is all that bad. 3. There is highly suspected to be a "cirtopic receptor" in the human eye, influencing circadian rhythms. I hear various figures for peak wavelength of sensitivity of that one and no figures for bandwidth. Figures for peak wavelength tend to be in the greenish-blue to very-bluish-green range. I suspect, in part from wide variation in determinations in peak wavelength for sensitivity, that the bandwidth is on the wide side - as in maybe similar to that of rods. So it appears to me that the cirtopic receptors don't get shortchanged much more than the rods do by an incandescent-like CFL in comparison to an incandescent of same color and same photometrics. 4. A somewhat-suspected separate "violet cone" that has its neural output being channeled into something like 80% blue 20% red neural channels: I suspect that such *may be true* since I have foveal tritanopia, and I find that defect in my vision to affect spectral pure deep blues but not spectral violets (such as the 404.7 nm wavelength of mercury). Should the "violet cone" actually exist, CFLs of incandescent-like color do stimulate that one as well as incandescents do - via the 404.7 nm wavelength of mercury vapor. 5. Suntanning/erythemic ultraviolet: Both incandescents and CFLs are similarly lacking in production of such. Erythemic UV found in daylight is mainly the longer wavelength 35% or so of UVB and the shorter wavelength 25-30% or so of UVA. 6. UVA of wavelengths absorbed by tryptophan and related compounds: I have yet to hear of anything good from that and I am aware of a harmful mechanism from that ("nuclear cataracts" ["permanent suntanning of the core of the lens of the eye], as well as contribution to the more-common foggy "regular" cataracts). Most of the trouble from this is "superlinear" with intensity of exposure. As in if exposure intensity is cut in half but imposed for twice as much time, you are better-off. The main offender here for a very large majority of the population is natural daylight. Both incandescents and incandescent-like CFLs run low in such wavelengths and do so similarly. Non-dollar-store CFLs and other triphosphor fluorescents of higher color temps. produce even less, due to the blue phosphor component used in these lamps utilizing the 365-366 nm mercury spectral feature - which other fluorescent lamp phosphors usually do not absorb. (2700K CFLs generally lack the usual blue phosphor of "triphosphor fluorescents".) 7. There is some notation to a wound-healing mechanism using deep red light of wavelengths around 660-670 nm. CFLs lack that. However, the study I saw noting a proposed actual photochemical mechanism also noted requirement of intensity of exposure to such wavelengths, easily fallen short from by direct sunlight, let alone home indoor lighting of any kind. 8. Acne treatment - the main acne bacterium does produce a waste product that is converted into something toxic to that bacterium by "mid-violet" wavelengths. Direct midday sunlight usually has enough of that to make a difference. Indoor home lighting, regardless of type, does not. Artificial lighting to blast acne bacteria is typically "03 super-actinic" fluorescent lamps, available from pet/aquarium shops among some other sources. Exposure requirement is high enough to require a lot of this - or preferably twice-daily or whatever 15 minutes or whatever amount of time blasting acne-befallen parts of your body by such a lamp mere inches away. 9. Photoreceptor in animals other than humans - live coral has a requirement for deep blue to bluish-violet wavelengths. 10. Photoreceptor in animals other than vertebrates - arthropods have a UV (probably UVA) photoreceptor in their eyes, occaisionally noted as having peak sensitivity around 350 nm. There are some other photochemical processes and photochemicals known to be in the plant kingdom, and notably found absent in anything that is into the animal kingdom enough to lack chloroplasts. (Euglenas are protozoa with both mitochondria and chloroplasts, and were considered to be within the "animal kingdom" until the kingdoms were redefined to make protozoa and slime molds [masses of amoebas - prorozoa] to be not considered animals. Bottom line: I see "preponderance of evidence" to a great extent that incandescent-like CFLs are not much more unhealthful to humans than incandescents of same photometric performance are, despite the spiky spectrum of CFLs. - Don Klipstein ) |

You do need adequate levels of natural light, but you dont need artificial light to duplicate that. cool white florescent etc..and others have that problem. a good google search....' full spectrum light, heatlh, Ott' Just because some fool claims it doesnt make it gospel. |

When I get up in the morning and turn on the bathroom light, I like the idea of it not blasting me until I wake up a little. BTW I mix traditional and fluorescent lamps. The end result is a very good color mix, somewhere between sunlight and standard lamps. So for the lady of the house who has makeup and clothing color mixing to do, it is great. |
