LED light bulbs-a report.
LED bulbs are promoted to replace incandescent and CFL bulbs and they
may be cost effective but the brightest ones you see are said to replace 75W incandescents, which might sound good but is a most unusual size. In my house, I had many 60W and 100W standard lamps but LED replacements for 100W are hard to find and expensive. To add insult to injury, sales of 100W incandescent bulbs are now forbidden. It seems inevitable that LED's should be expensive since the diodes run on DC and bulbs must incorporate converters. There are exactly four places in the house where I had 60W bulbs and I have bought replacement LED's for three of them when there were special sales but the three LED's cost a total of $50. Two of these are in enclosed fixtures where CFL's get hot and have proved not to last well. None of the LED replacements have blown in six months so far. -- Jim Silverton (Potomac, MD) Extraneous "not" in Reply To. |

I've been running a dozen or so LG 40W equiv LED lamps here for a year or so now. They are all performing beautifully and based on rated life expectancy I should have to replace them starting around 2030 or so. They were about $9 ea in two packs at Costco. |

The only place I have 40W bulbs is in appliances...inside the oven, inside the fridge, and inside the overhead fan above the stovetop. Where do you use a dozen? I would never read by a 40W bulb....I use a three-way 50-100-150 for reading. N. |

The first ones I got were Christmas lights and they drove me nuts. When I looked at them they made my eyes seem all blurry or something. The newer ones do not do this. I also had issues with the first LED flashlights I tried. They seemed to case a bit of distortion or something. These days I don't mind them in a flashlight or battery operated lamp but I wouldn't want to use them in my regular lamps and light fixtures. |

I bought a dimmer switch for my dining room chandelier recently and my brother, who installed it for me, was surprised to see it would work with halogen bulbs.

I'm pretty pleased with the LED lights in my house. At night I usually run only 3 LED lights, which use less than 15W for all three. They provide just enough ambient light throught the house. I never did like those CFLs, I've had a few break on me, which is just wonderful given all the toxins contained within. I also can often hear a high-pitched noise emanating from CFLs which drives me crazy. LEDs on the other hand at least don't have either problem to my knowledge. -- I wanna go like my grandfather... in his sleep. Not like the screaming passengers in his car! |

It will cost a fortune to replace all of them if it comes to that. I have seen one type that claims to "look like" incandescents, but they have a thick collar that will not fit in these fixtures.

I wanted my over the sink halogen light on a dimmer switch, but it made noise when it was dimmed - so it's just a regular on/off now. We just replaced an incandescent bulb in an older uplight that's on a not so new timer with a CFL that's supposed to burn like a 100 watt but use only 25. The timer is working properly, but only time will tell how long things last. > > I know that isn't what you're talking about, but your post made me think > of that. -- Food is an important part of a balanced diet. |

The same damn thing which happened here in Italy, LED and low consumption bulbs are all equivalents of those strange measures: 32, 75 and another one between them that I can't recall now. My kitchen is now 25% brighter than before after I put a low consumption 75 watt equivalent bulb in place of the old 60 w bulb -- "Un pasto senza vino e' come un giorno senza sole" Anthelme Brillat Savarin |

Energy efficiency is a good thing. But not if you have to pay out the nose when one burns out. And those twirly looking bulbs? They work fine for regular lamps. But I'd have to buy a new desk lamp. The lampshade has two wires that "grab" the round light bulb; that's what holds the shade in place rather than a finial. Oh, sure they make them in a regular lightbulb shape. But $16+ for one friggin light bulb? Ridiculous! http://tinyurl.com/blm8azt I'm not at all convinced LED's last longer, either. About 3 years ago I replaced the overhead fluorescent light fixture in the kitchen. That meant switching to the new LED tubes. Now it's not like I leave the lights on in the kitchen for hours on end. But I've had to replace all four bulbs twice over. Most recent was last fall and one of the LED bulbs has already burned out. They may be more energy efficient but they aren't very efficient on the pocketbook. Jill |

To add > insult to injury, sales of 100W incandescent bulbs are now forbidden. IIRC, there's been a postponement of the 100W incandescent sales ban in the US. Also, wattage equivalents aren't the best way to shop for replacements, since it is only an indication of power consumption, not light emission. Light output is measured in lumens, and there's no watt : lumen standard with light bulbs. Brand A's 60 watt incandescent may have a lower lumen rating than Brand B's 60 watt incandescent. You can even find 60W bulbs whose light output is pretty close to another brand's 75W. So check the packages for the lumens listed and choose accordingly. Color temperature is another factor we're going to have to start using when selecting bulbs. Incandescent bulbs tend to emit a warmer, yellower light (approx. 2700 - 3000 Kelvins) than the bluish-white light typically emitted by CFLs or LEDs (approx. 5000 - 7000 Kelvins). However, some of those bulbs have been designed to emit light in the warmer color range, so if you want to replicate the look of incandescent light, check the color rating on the package and see if it falls within the warm white range. > > It seems inevitable that LED's should be expensive since the diodes > run on DC and bulbs must incorporate converters. The quality and options in home LED lighting have made great gains in just the past year or so, while the prices are starting to significantly drop. So we're close to the tipping point where LEDs will surpass CFLs as the affordable replacement bulb of choice, and soon LED bulbs will be available with 100W equivalent or higher output. Just last week the latest and best incandescent-replacement LED bulbs hit the market: Cree 40W and 60W equivalent bulbs. Currently available only from Home Depot, they range in price from $9.97 - $13.97 each, and in warm white or cool white light output. They're also designed to mimic the appearance of a conventional incandescent bulb, making them an aesthetically suitable replacement as well as a very cost-effective one. Cree has a reputation for producing outstanding quality LED flashlight bulbs, and this is their first foray into the residential lighting market. Bonus: they're made in the USA, too. |

I have a circa 1956 Japanese lady tall table lamp. The socket for the bulb is surrounded by a deep glass shade which points upwards. On top of the glass surround sits a big round lamp shade; the ring of metal fits on the glass. The outer shade is stiff linen. It appears the linen shade is optional. Very odd design, but then I'm not all that familiar with 1950's decor except from old television shows. Anyway, it appears one of those CFL's would not work in this vintage lamp. But that lamp has a lot of sentimental value. I'm not about to get rid of it because of some screwy <G> lightbulbs. Jill |

I have no evidence on LED's; my enclosed ones are still doing well. There CAN be problems in enclosed fixtures, but not always. I ran them full time in outside fixtures, even in the summer sun, way hot. They lasted full stated hours, or about a year and a half. 24/7 Greg |

The only > part I don't like is how expensive they are to replace. Except they aren't expensive to replace. $10 or so for 30,000 hours+ of life vs. the incandescents or CFLs works out to be the same or less cost per hour. If you count your time replacing multiples of the incandescents or CFLs to one LED then you're way ahead. |

I always recommend that people ensure that they replace all the lamps in a given area with the same type of source and color temperature specification, otherwise they will frequently complain about how different the lights are. |

I tried two LEDs, they're much too harsh as a task light, they are more of a spot light, not good to light up a room... I also have a small LED flashlight, it's fine for that. I'm using a few CFLs; in a bedside lamp (not for reading), in the fixture over a bathroom sink (four 20W under a frosted glass shade) but it's enough light because there's an overhead ceiling fixture with incondescent bulbs too, and in a table lamp in my living room (again a shaded lamp not for reading). I don't like CFLs for reading or as overhead lighting, they're okay in lamps with shades. CFLs are fine for low level light in a room but not for doing tasks |
