Dimmable CFL
Hi,
Came across a 23W dimmable CFL. Got one to try it out. It worked ~2 hours and pop, it went to full brightness and no more dimmable??!! Are they this unreliable? Or I got bad one. |

Please tell us the details! The usual "dimmable CFL" to most looking for those means one that is safely usable with a "usual light dimmer". I find it hard to believe a lamp refusing completely to be dimmed by a usual-for-incandescent-type dimmer. Non-dimmable lamps tend to have short life expectancy when used with a dimmer against their instructions, and may blow the dimmer. Usually the lamp is what dies. - Don Klipstein ) |

I screwed it in side by side with 60W incdescent lamp, dimmed up and down a few times and noticed when dimmed too low it was scintillating. At certain point it quit doing that where I left it. Soon it went to full brightness while the other lamp was still dimmed. From then on it is no more dimming, just stay at full bightness. |

I don't believe that it should be expected to pop. I have 2 of them. They don't dim very well. By that I mean, when dimmed, they flicker quite a bit. The range is good if you can stand the blinkety blink. There are spots where they seem to settle down and be ok. BTW, I am using this on an X10 lamp module, so finding a "good" spot is quite difficult. With a real dimmer, it might be easier. |

Or I got bad one. I expect you got a dud. The dimmable CFL I experimented with seemed to work fine. It also performed a lot better after a day of full on burn in period which I presume helped get all the mercury vaporized and the phosphors settled. |

I suspect the ballast circuitry in the CFL had part of it fail, and the CFL converted itself into a conventional CFL. Those can have hardly any dimming and can appear to be at full brightness until the dimmer is dimmed past the point at which an incandescent has about 1/4 its normal brightness. They can also be hard on the dimmer. CFLs also often dim more slowly than incandescents do at first, being about half brightness (or more) at a point at which an incandescent is about 1/4 brightness. A CFL may start dimming more rapidly when dimmed almost to being off, or may just suddenly turn off. Special dimming ballasts for ballastless CFLs do better. - Don Klipstein ) |

I have seen some get slightly warmer or slightly cooler in color from change in current and change in temperature, but that's it. One complaint of dimming fluorescents is lack of the color getting warmer as the lamps are dimmed. The lighting can take on a "dreary gray" appearance with severe dimming as a result. - Don Klipstein ) |

Dimmable CFL
I have replaced 8 can lights with 16 watt dimmable bulbs and they are great
been in use about 1yr. I also replaced same situation lamps over my bar but on same circuit as flame type lamps on same dimmer. CFL lasted 2min. Seems like the CFL lamp is killed by voltage noise or disruption. Not going to plug CFL mfg unless asked. Frank |

Have you tried looking for a CFL with a warmer (lower) color temperature? Also if you try them be sure to try them for a few days since your eyes will adjust. |

Thanks, Pete, didn't know that. Unfortunately, I no longer have any of the floor lamps I could have used one in. We have several true antique tiffany-style glass and craftsman style lamps with mica shades that have either 2 or 3 pull chain sockets in them. However, I still use clear incandescent bulbs in them because the CFLs make them look extremely dull.

Have you tried looking for a CFL with a warmer (lower) color temperature? Also if you try them be sure to try them for a few days since your eyes will adjust. It's not just the color (warmth) of the light that's an issue. It's the transparency of an clear incandescent and the filiment showing through that causes the glass shades to glisten. I doubt there will ever be a CFL that can produce that effect. At least the upcoming ban on many incandescent bulbs will not include decorative bulbs like the very old style of swirled flame bulb. At least that's my understanding. Another option I've used in very old lighting with two bulbs is wiring them in series. The bulbs last forever and the color and intensity is just right. I have one fixture that remains on constantly, that the bulbs are probably 30 years old or older. As an aside, it's been said that Edison's home in Florida that is wired with DC power still has the working original bulbs throughout. -- Wayne Boatwright ------------------------------------------- Sunday, 04(IV)/27(XXVII)/08(MMVIII) ------------------------------------------- Today is: Rogation Sunday Countdown till Memorial Day 4wks 4hrs 55mins ------------------------------------------- 'Make it idiot proof and someone will make a better idiot.' ------------------------------------------- |

You have to be careful though because there are also some similar looking mogul based CFLs that are designed to directly replace HID lights such as mercury vapor without removing the HID ballast. CAUTION - most of those mogul screw base ballastless CFLs get overpowered in HID fixtures - should they work at all. CFLs of wattage over 50 watts (and for that matter also most under 50 watts) tend to either have their own internal ballasts or require ballasts specific to themselves as opposed to ballasts for mercury or other HID lamps. Do not put a mogul base CFL into a 175 watt mercury fixture unless it is rated for use in a 175 watt mercury fixture and also has the ANSI "ballast compatibility" code of H39. Other HID "retrofit lamps" have other ANSI "ballast compatibility" codes on either the bulb or the package or in any inserted printed material. Use those in HID fixtures only if the fixture and/or the ballast has an ANSI "ballast compatibility" code same as one for the lamp (lightbulb). Otherwise, there is probability or possibility of malfunction, including significant chance that malfunction will occur "down the road" should the lamp work "apparently OK" initially. Such malfunctions may include hazardous ones. Keep in mind that there is such a thing as ballastless mogul screw base CFLs that lack any ANSI "ballast compatibility" codes. Those require ballasts/fixtures recommended by the lamp manufacturer, which may be proprietary ones. The best example that I can think of is Lights of America "Fluorex" lamps, widely available at Home Depot. - Don Klipstein ) |

They somewhat get away with lack of preheating those filaments during starting, but the "hot cathode" "filament style" electrodes are still what is there! Availability to force starting without preheating the filament electrodes is "Instant Start". This is opposed to "Rapid Start", "Program Start", and a couple other schemes. True instant start is something that I think goes at best at own risk when dimming is used! - Don Klipstein ) |

The bulbs last forever and the color and intensity is just right. I have one fixture that remains on constantly, that the bulbs are probably 30 years old or older. As an aside, it's been said that Edison's home in Florida that is wired with DC power still has the working original bulbs throughout. Just keep in mind that such century-life incandescents have energy efficiency so low that in order to produce a given amount of light, you increase your electric bill more than you decrease your lightbulb replacement costs. The first-mass-marketed carbon filament incandescents had energy efficiency of a couple to at most a few lumens per watt. There is a "centennial bulb" with a webcam showing a publicly accessable view of it continuing to work. I give low odds of its energy efficiency exceeding that of a 230 volt incandescent being powered by 120 volts, or roughly 1/4-1/3 that of modern 60-100 watt 750-1000 hour incandescents. http://www.centennialbulb.org - Don Klipstein ) I've no doubt of the inefficiency, but thought it was interesting, and I've seen the Centennial Bulb before. Just thought it was a curiosity. As a further aside, my dad had a habit of installing double light fixtures with 25 watt bulbs at strategic places throughout the house and basement, wired in series, to produce a very low light level. He didn't like walking into dark rooms, especially when the light switch wasn't near the entry. To him, of course, this wasn't a waste of energy. Of course, this was in an era when energy consumption was not an issue or concern. Hi, For low lighting I use LED bulbs. They consume only 3W per bulb. Few different colors. Soon I hope LED will replace CFLs. |

CFLs usually don't have a filament as in the long tubes. They do have an electrode at each end. The filaments in the standard tubes are used as heaters to help in starting. CFLs use a higher voltage that don't require the pre-heater. In instant-start hot cathode fluorescents including instant start CFLs, the electrodes are still in the form of filaments. Also, many hot cathode CFLs are not true instant start but "program start" or "trigger start" ("rapid start" with filament heating current reduced once the lamp gets started). The filaments actually get preheated in those. Cold cathode CFLs don't have filaments, but few CFLs are cold cathode. I have never seen Home Depot carrying more than one cold cathode model - the 3 watt N:Vision one. And I was there yesterday. - Don Klipstein ) |

Yes, I believe that, and almost all the incandescent bulbs I have in my home are 130v-rated. Their logevity is astounding. They use more electricity, however. Hmmm, I don't think so. 130V rated lamp is on 120V circuit. Simple Ohm's law. A 130V incandescent being operated at 120 volts consumes about 89%, maybe 88% of rated power. (Not 85% - the filament's resistance varies directly with temperature.) And when a 130V incandescent is operated at 120 volts, it produces about 75-76% of its full light output. Efficiency decreases a lot when an incandescent is underpowered. A 130V 100W incandescent only outshines a 75W 120V one due to incandescents having "economies of scale" that reduce the efficiency of lower wattage and lower current ones. A 75W 120V incandescent produces about 69% of the light of a 100W one. One more note: If you have incandescents on a dimmer and usually operate them dimmed, consider using a lower wattage to use less dimming. Although a 75W incandescent produces 69% of the light of a 100 watt one, a 100 watt one dimmed to consume 75 watts has about 53% of its full output. That leads to another consideration: Reduce the number of bulbs if you can - a smaller number of higher wattage bulbs will be slightly more efficient than a larger number of lower wattage ones. Just don't take this to an extreme that affects evenness of illumination. - Don Klipstein ) |

What I hear is that there simply isn't that much more around here (USA) -- that the biggest such find is almost guaranteed to be smaller than Alaska (which apparantely just isn't all that big.) Then there's oil from "oil shale", I understand, like up in Canada, and there's supposed to be *lots* of it, the only problem being that's it's (apparantely) BY FAR the "dirtiest" type, with (maybe) equiv effect on the atmosphere, etc. We also need to start building more nuclear-powered, electricity generating stations.

And with the kind of money they have for "lobbying" (ie bribes), they'll probably get it. Insane. If you're gonna build the things, at least do it out in Nevada or the Dakotas where if something blows you don't throw the entire nation info a bottomless depression from having to abandon the entire East Coast from D.C. to Boston. No thanks to prohibitive legislative and environmental enactments, it takes YEARS just to do the paperwork for a new nuke. That needs to be whittled-down to a couple of years at most. It's only 2008 and we apparently can't WAIT to forget about 9/11. (2001 for those of you that forgot.) That too. Had Osama been a bit smarter, he'd of have those planes dive into the spent-fuel ponds right there next to those nuclear plants. Next March 28, it will be thirty YEARS since the TMI2 (Three Mile Island Unit 2) "accident" and we can apparently NEVER forget. And how long ago was Chernoble (sp?)? And the effect of that on having to abandon a huge amount of land? And what about the wind-effect, carrying the radiation clear across western Europe? And its food-supply? Which event killed more people? Carbon footprint? When compared to a nuclear power station, an equivalent coal-fired operation has a *HUGE* footprint. It's fuel is delivered 2-3 times a week by the 100-car TRAINLOAD. It adds to the MOUNTAIN of coal that a station keeps on hand.
