LED replacements hit stores empty of 100W bulbs
Source: AP-Excite
By PETER SVENSSON NEW YORK (AP) - Sorry to see 100-watt bulbs disappear from stores because they were energy hogs? You can now get LED bulbs that roughly match the 100-watters for size and brightness, but use far less energy. Until recently, your only alternative was a compact fluorescent bulb, which has several drawbacks compared with light-emitting diodes. Most people see the light quality as less pleasing, and the bulbs contain a small amount of mercury that's released if the glass breaks. LEDs, by contrast, don't contain any volatile, hazardous substances and are durable. They also last longer. Osram Sylvania, a division of Germany's Siemens AG (SI), said Monday that it's shipping the first batches of its Ultra LED bulb to some Lowe's stores. The bulb uses 20 watts of electricity and costs $50. It's slightly larger than a regular 100-watt bulb, so it may not fit in all fixtures. Osram claims 25,000 hours of use, or more than 20 times the lifespan of a standard, incandescent bulb. Competitors aren't far behind. Royal Philips Electronics NV plans to start selling its own, slightly brighter 100-watt-equivalent LED bulb at Home Depot's website starting in a few weeks for about $55. Startup Switch Lighting Bulb Co., with its unusual liquid-filled bulbs, plans to start selling 100-watt equivalents late this year or in January. FULL story at link.

This image provided by Osram Sylvania shows what the company says is the first bulb that uses light-emitting diodes that shine as brightly as regular 100-watt bulbs. The bulbs provide an alternative to compact fluorescents. The federal government banned the production of regular 100-watt bulbs at the start of the year. (AP Photo/Osram Sylvania)

I need a daylight or Ott equivalent bulb (5500-5900K) for doing my needlework. Ott had a nice LED flip light that I bought and love but it's now discontinued - I don't know why. That is a portable lamp, though, and not appropriate for using everyday. |

62. The Home Depot bulb specs say: Lumens per Watt: 64.7
|
So for 17-watts that would be 17*64.7 lumens = 1099.9 lumens.
A normal 75 watt incandescent bulb produces about 1,200 lumens so the LED is within 10%. ( http://en.wikipedia.org/wiki/Incandescent_light_bulb ) |

73. That's a heck of a rounding up!
|
Oh well, I guess I can look forward to remembering when we had *real* light bulbs that had to be changed more often than once a decade; that could be used to warm our hatchling chicks - and our hands on cold days; that cost a dime each; that used more electricity than the average refrigerator (I'm hoping by the time I am relating this to my great-great-great-nieces &-nephews that would be true).
A couple of things I am looking at - the LED bulbs do not seem to have the size problem that the CFL bulbs do. In most of our house we are using CFL but we have some fixtures that they are just too big for. My husband just bought a pack of old style 75W bulbs to put in some of those - we've burned out the first bulb since we moved in. I may go get a LED bulb to try in those fixtures. Another advantage is that it appears the LEDs can be dimmed - I've got some fixtures that we did not put dimmers on because we were using CFLs but I may replace those controls once we replace the CFLs with LEDs. It will be a while, but I can plan on that down the road! |

78. That's not entirely true.

I have LED "can floods" I bought at Home Depot. As I recall they are rated at about 950 lumens. They appear much brighter than the 75W incandescent bulbs they replaced. That may be slightly deceptive because it is a whiter light, so the light may see brighter than the lumens would indicate.
Nonetheless, they are plenty bright. The issue is cost. Those were about $30 each. At that price they will pay for themselves over their life. But that is a lot of money for people to pay for a single light. |

CFLs have a limited number of on/off cycles, and aren't really good for light sockets that are turned on-off about 20 times a day.
They are best used when you are going to turn on the light and leave it on for several hours. |

12. The issue is that the electronics in a CFL is good for 6,000 on/off cycles. An incandescent has
|
been improved over the past century to be good for 1 million on/off cycles.
So all those claims about CFLs being good for up 6,000 hours and up to 7 years, that's based on leaving them on for at least one hour continuously each day. If you turn a CFL on and off 20 to 30 times a day, then the real lifespan will be about 200 days or a little over 6 months. I typically go into my kitchen and spend about 30 seconds to a minute each time. Bathroom, anywhere from 2 minutes to 10 minutes. If I were to spend at least 30 minutes in my kitchen or bathroom each time, then yes, I'd use CFLs. If they improved CFLs to be 60,000 cycles, then that would also make them last much longer for frequent on/off daily use. Then they would easily last 5 years. |

Including 1 on the front porch, which is on 24/7 and 2 in a photo cell controlled fixture. Some CFL are only turned on for minutes, then off again. We have never replaced any so far. As I said 2 years here so far.
Before I moved down here, I had replace all the lights with CFL and notice a dramatic drop in the power bill. I pay extra for good quality bulbs, that may be the reason I don't have the problems that some other people do with them. |

14. I think it has to do with the innards of the CFL.
|
I noticed the CFL bulbs in my bathroom quit working twice after about a year and a half. The bulbs in other rooms still worked after 3 years. They're supposed to last about 7 years. Might be a coincidence, but the incandescents lasted longer than the CFL in the bathroom. You can imagine how pissed I was spending 7 dollars, at the time, for bulbs that didn't last as long as the ones that cost maybe a buck.

Because Philips sucks.
I like to read late at night in the bathroom. Takes about 3-5 minutes for the four vanity CFL's to reach a tolerable light level. Fairly pathetic performance. Plus I am on the THIRD bulb generation in three years in there. I laugh out loud every time I read the expected life propoganda on the boxes these days. I figured that the expected lifespans are from laboratory testing and done before they've been redesigned by the guy cutting costs on the production line. All in all: NOT a CFL fan. Better than incandescent for energy reasons, but a poor technology in terms of reliability, cost and functionality. I'll go LED the moment economies of scale drive the price down a bit. |

Model EDXO-14 5000K 120V 60Hz 14W 0.230A V#42836 There were most likely purchased at Home Depot. I, fancying myself as being an amateur photographer and my SO as being an artist, so we both like the white light they put out. 5.0 out of 5 stars Don't listen to the other reviews, know what you are buying..., January 3, 2011
By Avalon Amazon Verified Purchase(What's this?) This review is from: Ecosmart 14 Watt Daylight 4 - Pack (60 Watt Equivalent) These are 60 watt equv. daylight bulbs! people who wrote bad reviews because they were too bright or too blue or not warm should have known what they were buying! I have been using CFL bulbs for about 3-4 years now and these are some of the better ones I used. I put all 4 of them in our bathroom and they are pretty much instant on, which is a first for me with CFL, the soft/warm ones I have used in the past took a while to brighten up, these give you instant light and still get brighter a minute later. These are meant to be WHITE, not yellow lights, they are meant to simulate daylight and do a good job, great for closets and bathrooms, maybe kitchens, but not really meant for living rooms, dining rooms or places you prefer softer yellow light. You can love and hate these because in a bathroom it will show you a true picture of how you look! Ever put on clothes or makeup in a warm lighted bathroom, then go outside on a sunny day and you look different than you thought, thats because the warm lighting gives you a false sense of how you and colors look compared to daylight, these give you a better idea of what things will look like in "daylight". They do seem brighter than 60 watt warm/soft yellow lights because of it being a white/blue light. Blue makes things appear brighter to our eyes, so even though its still 60 watts of energy (or 14w in this case) a white/blue light will appear brighter to us than a yellow light. http://www.amazon.com/review/R30DKSMV3TCXED/ref=cm_cr_pr_viewpnt#R30DKSMV3TCXED (Disclaimer: I did not write the review.) |

The idea that you have to make it as bright as day indoors at night is new. You would be surprised how little light you actually need if it's placed in the center of the room near the ceiling. A single nightlight bulb in a 15x15 room will light it just fine for normal use. At least enough to prevent stepping on the cat in the dark.
I lived beyond phone and electric lines in the 80s and rigged a 12v lighting system in the house using turn indicator bulbs which are actually rather bright. |

|
If you have cataracts in your eyes, fluorescents will stimulate their growth. Also, my eyes go in and out of focus with fluorescent bulbs.. I can not use them. I turn them off in my office and use lamps. I hope the new LEDs do not have the same problem.
Saving money is not always the primary issue. I am sure I am not alone. I have been concerned that my health and vision would suffer if incandescent bulbs were unavailable and fluorescent lighting was the only available option. |

23. We bought LED bulbs for our bathroom just after we bought our house
|
It was a bit of an investment at $27 per bulb. They give off no heat (which is nice during the summer when it is really hot) and they are brighter then any other bulb I've seen. The bulbs should last through when we plan to sell the house 5 years down the road. It's a shame all the other lights in the house use the damn florescent lights (the long ones). I'd love to replace all of them with the LEDs.

That's a choice between eating this week and not. The LED bulbs I've tried so far had a 17% failure rate within three months. I'd also like to see where they're made and which company ultimately ends up bringing them to market because I'll be damned if I'm going to shovel $50 per bulb into the hands of some numbered corporation bringing in lead from the PRC and trading on the name of a company I might recognize from decades past.

The LED bulbs I've tried so far had a 17% failure rate within three months.
Take them back to the store for a refund or exchange. I had the same problems with CFLs when they first came out. It got to where I stated marking the purchase date on the base of the bulbs with a sharpie so I could return them if they died before their warranty. Also early models were slow to turn on and slow to come up to full brightness. Newer CFLs are much better. I expect a similar curve for LED bulbs. |

72. Would if I could. They came from a Costco in Detroit.
|
I was there on a family visit and that was the only place I've ever found them for anything less than a pound of flesh. I live at the opposite end of the lake and the closest Costco to me is a four hour drive to Pittsburgh or Cleveland. For whatever reason, they seem to hate the idea of opening a location here.

79. I have a couple dozen of them and have had no failures
|
I did have a bunch of failures (some scary) if CFLs, but no failures of any LED lights. They do generate a lot of heat and if this heat is not dissipated, then it will cause the electronics to fail. In other words, they may not work in an enclosed fixture (globe, etc.) And that does present a problem as 60W and 40W are banned.

30. It's a good value, but...
|
It costs about $4 to run a 100W incandescent light bulb for 24 hours.
The article claims a lifespan of 25,000 hours, or 20 times an incandescent. Which means the incandescent they claim has a life of 1250 hours. This is a difference of 23,750 hours. At $4 per 24 hours, that is $.17/hour. So if you ran an incandescent bulb running an extra $23,750 hours (2.7 years) at $.17/hour would cost you almost $4000 in electricity! So the bulb definitely pays for itself. But how many lightbulbs do you have in your home? I figure around 45. To replace them all with LEDs would cost $2475. That's a pretty significant capital outlay for most people. The good news is they will be coming down in price. |

59. How many of those 45 would see constant use, though?
|
Here it's a couple of the bedrooms, one washroom, the basement rec room (only one bulb there), and the living/dining room (four bulbs between the two). The rec room and L/D rooms are almost never both occupied, and the kitchen's got a normal light that's only on for a couple hours an evening depending on light levels, with a dim fluorescent being used any other time it's in use later at night. All the rest are on on a "someone's currently using the room" basis, which usually isn't more than a couple minutes.
If someone's got a house with that many bulbs that are all going all the time, they're frankly Doing It Wrong anyway and would probably be able to save enough to upgrade the most commonly-used lights just by improving their habits. |

|

It doesn't matter. I was simply pointing out that if you replaced all 45 at $55 a bulb it would cost you about $2500 to do it. My point is, it's still quite a capital outlay at $55 a bulb to install them. But, like I said, the price will come down. Steve |

63. Depends on your power rate but you may be too high..
|
...locally here in the Tampa Bay area it costs me about $100 for a full year of 100w left on full time,(about $.10 a kilowatt) or about $8.33 a month or $2.08 a week or $.29 a day or a little over $.001 a hour. At that rate a $50 bulb would pay off practically never?

Too many competing standards. Too much fiddling with settings. But the new Philips Hue LED light bulbs could finally flip the switch for American homeowners by tying them to something they already love: their smartphones.....

80. There are LOADS of dimmable LEDs out there

Last edited Wed Nov 14, 2012, 09:20 AM USA/ET - Edit history (1) I just bought some for my bathroom vanity. The one I got at Home Depot wasn't ideal. It seemed to have a pinpoint of light which looked strange, and it had an audible buzz. But I got some from an Amazon dealer and they were great.
See http://www.amazon.com/gp/product/B006M93T3S/ref=oh_details_o01_s00_i00 At $27 bucks each it isn't very practical, but I was interested in testing the state of the art. The dimming works fine, but does not dim at the same rate as the incandescent lights. So I really need to replace all of the bulbs. I think I'll wait until they get closer to $10. The vanity lights are a specialty product. It is very easy to find dimmable LEDs to replace normal bulbs and floods. What I have not seen is an LED replacement for a 3-way light. |

Let me ask you, when you try dimming the LED light, how does it do at the low end of the dim? Does it dim out or just shut off? If you have experienced bad dimmable lights, you'll know what I mean.

58. False equivalency.
|
A 100W incandescent (tungsten) light bulb draws one hundred watts of power from the wall, and produces about 1750 lumens (light that we can see) at 2.6% efficiency, with the rest of the radiation emitted as heat. This isn't so bad in the winter time, as the resulting heat from incandescent bulbs helps heat your residence and reduces the amount of time your furnace has to run, but in the summer, you fight that wasted heat and pump it outside using your air conditioner.
The LED bulb that produces "100 watts of light using 20 watts of electricity" is surprisingly inefficient, in LED standards. LED lighting typically draws only 10% of incandescent lighting... these high-powered LED bulbs must be more inefficient because they require some form of self-cooling to keep them from burning up. To clarify my original point, the LED bulb is drawing 20W to produce 1750 lumens (approximately). The 100W tungsten bulb is drawing 100W to produce 1750 lumens and provides you with extra warmth in the winter and a big hot pain in the ass in the summer. |

68. Color Temp / CRI
|
The color temp is 2700K for anyone wondering.
The color rendering index (the spectrum available to keep things looking washed out) is CRI 80 -- which is better than most CFL's, but still no where near as good as incandescent bulbs. For point of reference, the CRI of both the sun and an incandescent is 100. I am an amateur photographer, and really wish better lights were available which also used less energy. |

70. By my math, I have about a 15 year supply of 100 watters in my attic.
|
I have CFL's in most of my house, but I've returned every LED I've bought to the store. They make ugly, artificial light that gives me headaches. FWIW, LED TV's and Christmas lights also give me migranes...that particular technology is simply incompatible with my brain. Even the LED powered screen on tablets can give me a headache (luckily, my laptop uses a cold cathode tube that I don't have a problem with).
If you Google it, you'll find that it's a well known and understood problem. The light spectrum emitted by LED bulbs tweaks the rods in the back of your eye that you use for night vision. This causes eye fatigue in many people, and is responsible for the widespread opinion that LED light is "harsh". For people with particularly sensitive rods, the result can be physically painful, and the eye fatigue can lead to headaches. That's me. I have incredibly good night vision (which I attribute to a half a lifetime spent staring through telescopes), but cannot be in an LED lit room for more than 5 minutes before my eyes get uncomfortable, and 10 minutes before the headaches start. It's not a matter of brightness, but of spectrum. |

83. I haven't been able to find an answer to this question:
|
I recently bought a CFL bulb for my bedroom ceiling fixture. Price was higher than regular bulbs, but I thought it may save me from having to get up on a chair to change bulbs for quite a while. Then I noticed something odd. When I turn on the fixture, the light is nice and bright. Within about a minute and a half, it dims. Not a lot, but definitely noticeable. I went back to the hardware store where I bought it to ask if I had a faulty bulb or if this was one of the quirks of this type of bulb. Not one person there could answer. Since I frequently sit in my room to do embroidery, knitting, etc., the light is important.
So, have any of you had the same problem? Is it a faulty bulb or an oddity? I'm going to have to store up on regular bulbs because at $50 a bulb, I won't be replacing any. |
