LED Lightbulbs and antique lamps
Hi,
I own 3 very old lamps with slag glass shades. I bought a new LED bulb to try out because I don't have any more of the incandescent bulbs left, and wanted to see what kind of light they throw before I needed one.
The LED is way too tall. I can't replace the harp with a taller one (the thingy that holds the lampshade on) because it would expose the socket.
Any ideas? These lamps are worth a small fortune and have been in my family for over 100 years, and I use them every day. I sure don't want to have to replace them just because of bulbs. Thanks.

1. I have a wide range of LEDs that I've collected over 8 years or longer.
More and more become available every month- Your problem was also seen with CFLs until they offered more sizes and form factors.
If you shop around between the different home improvement stores you might find the right fit-- Feit, Phillips, EcoSmart and others are sold, but at different stores (not all that Home Depot carry are also at Lowe's, for example).
If you can't find what will fit in a medium Edison base (the typical screw type), you might find something smaller with an intermediate base, and then use an adapter.
Not sure what lighting equivalent you're looking for (40W, 60W, 75W or 100W), but Feit has a range that look smaller than typical incandescents:

Okay, I'm not too happy about it, but I had to get around to it sooner or later.
I used to challenge Skippy's knowledge of things practical, as did many others here.
But that was before I learned of Skippy's background and academic accomplishments; in case one doesn't know by now (sometimes when I distribute information, I miss a few people), Skippy, a poor dirt-farming boy out in California, attended one of the finest engineering colleges in America, and that on a full-ride scholarship.
Skippy's one primitive who never had to worry about student loans.
So, reluctantly I must concede that Skippy, while abysmally, woefully, dreadfully, disgustingly, ignorant of so many other things, including civics, politics, economics, how to win friends and influence people, and decent haberdashery, does know stuff like this.
<<<admits when wrong, which is more than any primitive ever does.

2. I've spent several hundred dollars at...
www.SuperBrightLEDs.com there past couple of years, mostly on lights for my car, but I've yet to have a problem with then.
they give pretty exhaustive information, including dimensions, of their stuff so your can see if it fits or not.
you can search by base size as well. if yours has a "regular" base, which is the 26mm Edison, you can screw in an adapter to convert it to "intermediate" (17mm) or "candelabra" (12mm) size.

4. I'd suggest you look for a CFL that fits...
I know all the talk is about LEDs, but a direct comparison between LEDs and compact fluorescents show very little difference in "wattage per lumen" so there's no effect on your electric bill whichever you choose.
LEDs also have really lousy color. There's something called the "color rendering index", or CRI, used by lighting engineers and designers where 100 is perfect and anything below about 85 is crap. Fluorescents can be found in the 90s, while LEDs are up there are extremely rare and tend to cluster around 70. Incandescents and quartz/halogen are about 100.
And the the price-- 10-25 bucks for a dim bulb with lousy color?
There's no reason why LEDs won't become cost effective and have better light in the future, and some say they should be there now, but for now there's little reason to go there. The one big problem with CFLs in your case is that the more light you want, usually the bigger the bulb, so you are limited in wattage if you want to fit under that harp.
And, incandescent bulbs haven't completely disappeared, just some shapes and wattages. Quartz halogen, which are slightly more efficient than incandescent, might be around forever.
<<<wouldn't trust this ^^^ primitive to boil a pot of beans.

8. CRI improving more and more, now >90, and LEDs more than pay for selves in life span alone.
New CREE chips:
http://online.wsj.com/article/PR-CO-20140129-910210.html
Cost comparison from 2010:
Students use a table to compare the cost of bulbs and cost of electricity to operate each bulb type for 30,000 hours.
Bulb Type Bulbs needed for 30,000 hours
Total Bulb Cost plus Electricity Used @ 15¢/kWh
Bulbs + Electricity
Incandescent
38 watts 30 $30.00 38 W x 30,000 hr
= 1,140,000 Wh 1,140 kWh $171.00 Total for lamps plus power= $201.00
CFL
9 watts 4.28 $29.66 9 W x 30,000 hr
= 270,000 Wh 270 kWh $40.50 Total for lamps plus power= $69.66
Feit LED
6.5 watts 1 $20.00 6.5 W x 30,000 hr
= 195,000 Wh 195 kWh $29.25 Total for lamps plus power= $49.45
And they're cheaper now.

9. The Cree chips are neat, although...
not unique. But, with the drivers and fixtures needed, not exactly what a homeowner needs for a couple of antique lamps. I've seen extraordinary lumen output in the lab, too, but first there are those industrial new builds, then refits and later come the homes.
As far as the calculations for 30,000 hours go-- you do realize that's about 7 years at a 50% duty cycle. And to compare 9W with 6.5W without a lumen count is deceptive, but even if they are the same output, 20 bucks over 7 years approaches meaningless. I probably should ask what "4.28 $29.66" means, but doubt it will change anything.

Maybe you would be correct dummie... but it has been my experience that the CFL's do not last near as long as the lab tests indicate. Yes dummie... I got clean power. My Dad was a master electrician. I got good power. Not to mention the CFL's have a nasty habit of catching on fire when the ballast screws up. The LEDs I ain't tried. Ain't paying what they want for them.
I bought cases of the tried and true bulbs before the gummint outlawed them. If you dummies want to purchase some from me, come over here and let me know. I'll tell you to piss off. :-)

I've bought a number of LED lightbulbs at IKEA, and they are actually pretty fantastic. They act very much like incandescents in their amount of light and color. A little pricey, yes, but I do think that they helped with my electric bill, and they should last a very long time.

I'm not that surprised that Skippy knows so much about energy, he does teach it for a living. I know he'll be happy when that beach condo gets out of escrow, and it'll be any day now.

I had a dream last night.
Now, most of my dreams involve people I know in real life, although a good plurality of them involve people long ago dead but in their own time were well-known. But once in a while I have a dream involving a primitive.
I dreamed I was a congressman from Nebraska; a 100% rating with the ACU, the NRA, the right-to-life groups, beloved by both establishment Republicans and the Tea Party. The only campaign expenditures I had to make were the filing fees, despite that the Democrats spent tons of money trying to defeat me; one time, they even carpetbagged a Kennedy into Nebraska, figuring nobody could beat a Kennedy.
I was so busy I needed a right-hand man. I hired Skippy--I'd wanted to hire Manny, but Manny was unavailable--because he impressed me with his brilliant cerebrality; he was not only the smartest person I interviewed, but the smartest person I'd ever met in my life, period.
There were two problems, though. In case one hasn't been paying attention, Skippy's far to the left of even the primitives; he makes his ancient mentor the old terrorist William Ayres look like Mohatma Gandhi, and the late Yassir Arafat look like Mother Theresa. I dunno how that happened, but if the late Idi Amin had met him, he would've found Skippy agreeable companionship.
No big deal, I figured; I could take care of the politics, while Skippy took care of everything else.
The other problem was his state of haberdash; he obviously buys his clothing by mail-order from Blair of Warren, Pennsylvania or Haband of Oakland, New Jersey; all that polyester stuff. I took care of this by hiring the big guy from Bellevue, as a wardrobe consultant for Skippy.
All went well for a while, although there seemed some discombulation in the most popular congressman representing Nebraska; a slow-but-discernible shift to the left, the far left. I kept on being re-elected, but it was apparent the constituents were getting less and less fond of my politics.
The last straw was when I submitted a bill to put the portrait of the late Pol Pot on the twenty-dollar bill, and entertained Kim Jong-un out here in the Sandhills. That was so "left" it upset even Robert Mugabe.
I got yelled at a lot, by other Republicans. Finally, I said screw it, and joined the Democrat party, because I wanted to be with the majority, not the impotent minority.
However, much to my surprise, while I squeaked through re-election despite my new party label, abruptly the Democrats were in the minority--and a tiny minority at that--and so I was still screwed.
I decided I had to return to those values and principles that'd made me a decent and civilized person in the past, and informed Skippy thusly. He arched his eyebrows, but said nothing.

That evening, when I went home, as I touched the door-knob to the front door, I felt a wire that hadn't been there before, and quickly yanked back my hand. I contacted the police, who came over to investigate.
What they found was that the wire, when twisted by the door-knob, was set to detonate a bomb that would chain-react into circa 60,000 tons of dynamite, blowing me heavenward.
The cops were awed. "It took a guy smarter than Einstein, to design this," they said.
They were about ready to put out an all-points-bulletin for Skippy when one of the cats jumped on my stomach, waking me up.

I bought shit loads of 60, 75, and 100 watt incandescent light bulb last year. Delivered to my door for ..14, .21, and .72 dollars respectively. I have enough to last decades for my use. After the beginning of the year I now see those same lamps going for $1.25-1.50, $1.47-2.50, and $2.28-43.50.
That is a better ROI than on .22LR.
-
Wait 'til DUmmies realize they have to replace fifty-cent light bulbs with six-dollar democrat bulbs.
And those six-dollar bulbs will fail in a few weeks if the fixture is enclosed in any way.
They are, at least, easy on your eyes since they come on gradually, taking a couple of minutes to reach full light.
Democrat bulbs are as good a deal as democrat health insurance.

Dear DUmmie Holly Hobby:
Go to Dollar General and pick up some incandescents. Or ask around your neighborhood to see if there's a hoarder around. There is no way I'd put one of these democrat bulbs in a valuable antique lamp that I cared about.
IIRC, Congress decided to allocate no funds to actual enforcement. I can still find 100 watt ones. I am well stocked.

Yeah, that's what freaks me.
The late philanthropist Peter Cooper gave Skippy a state-of-the-art education in engineering, with the idea that Skippy would go out and design skycrapers and monuments and bridges and dams and roads and stuff, and make a good income doing so.
And obviously, way back when he was young, Skippy showed such an aptitude; it's excruciatingly difficult to qualify for the late philanthropist Peter Cooper's benevolence, and Skippy made the cut.
Why the Hell he just up and decided to become a grade school teacher, a governmental employee, flummoxes me. He's making scads of money right now as a public employee, but he'd be making even more as a professional engineer or architect.

I've experimented with a few, I do like the performance and the durability.
I have one ceiling lamp that has a bad habit of blowing out bulbs regardless of wattage in a short time because the interior of it gets too hot for them. I've even blown out oven bulbs in it. CFL fares no better.
However, since replacing the bulbs with dimmable LEDs, the lamp has remained lighted for the last few years. I've also used LEDs to light up the coin slots in my retrofitted arcade cabinet. Those have been in there and in service for about six years without failure. (oddly enough, the bulbs in the arcade came from the website suggested by the primitive, www.SuperBrightLEDs.com . )
Anyway, to address the Holly_Hobby primitive -
The Dimmable LEDs in the ceiling fixture scale 1to1 with a typical incandescent bulb. So, I'm not sure what she is going on about.
-
I bought an $800 ceiling fan/light for the kitchen that uses only 100 watt bulbs just before the democrat bulbs were mandated.
If I put 60 watt bulbs in it, you can't see crap. NOTHING ELSE FITS.
GE puts out a "100 watt equivalent bulb that's actually a 72 watt bulb".....f****** democrat liars.
So I bought a case of 48, 100 watt bulbs for $$$$$.
Democrats suck and so do liberal republicans.
