Your 1000 bulbs link is a size A21, not A19. The other looks like it might prove me wrong. Only 1520 lumens, but I'm not going to quibble over 5%.
I guess the question is this...
What does the "lighting facts" sticker look like for that bulb?

100 watt dimmable $25 and change.
From a 12 second google search.

My bad...the A19 is right below the A21.
Haven't found a "lighting fact" for it yet for consistent comparisons. The bulb is within A19 lengths, but a larger diameter and still may not work in all A19 applications.
Thanx for the link. Now I'm going to have to order at least one of those D100's.
I received my Nanoleaf today. It fits in the fixture that the Cree wouldn't. However, I like the Cree better because it is the 5000 K color. The Nanoleaf is 3500 K.
Rather than order the D100, I'm going to go locally with Batteries Plus. They have one that looks good:
It uses 22.5 watts for 1640 lumens and it looks like it will fit nicely in the A19 size. I will buy the Cree's for most other places.
I finally made it over to Batteries Plus about an hour ago and bought two of the Duracell 100 watt equivalents pictured in my last post. They are a true A19 size, measuring 19/8 (2-3/8) of an inch in diameter.
Very nice output and color, but they do use 22.5 watts. Also spendy at $39.99 each. If you want a true A19 size and 1640 lumens, this is the one to buy.
A few days ago, I bought more of the Cree 100 watt equivalents. 1600 lumen for 18 watts. I now have 16 of them at $20.97 each.
http://qz.com/206252/americas-dracon...ght-new-ideas/Back in 2012, the U.S. government started phasing out incandescent light bulbs, in an attempt to turn Americans on to energy-efficient alternatives. The reaction has mostly been underwhelming—incandescents still outsell more efficient alternatives like LEDs and compact fluorescents, and make up 65% of lightbulb shipments, due to leftover inventory from before the bans, along with regulation-compliant halogens.
However, the New York Times reports that two companies are debuting new bulb technologies, hoping to cash in on the desire for the same warm glow as Edison’s big idea in a more environmentally palatable package—if not the relatively low price.
The first entrant is called Finally, as in: Finally, here’s an eco-friendly, somewhat cheap (8$) bulb that won’t make your room glow like a chain-store pharmacy. These bulbs pump a magnetic field through a tiny piece of solid mercury, which creates ultraviolet light. The ultraviolet light agitates a phosphor coating on the inside of the glass, emitting visible light.
Another technology called Vu1 creates light using technology similar to the cathode rays that used to power old TVs. It was supposed to debut three years ago, but has had some manufacturing issues. Vu1 has only designed flood-style bulbs for recessed fixtures so far. Each bulb costs $15, is mercury-free, and is supposed to have a warm light that’s similar to incandescent bulbs.
In the meantime, if you are an environmental scofflaw, you can get incandescent bulbs on the internet for a little more than a dollar apiece.
I bought this LED worklight a couple months ago and it kicks ing ass. Doesnt' look like any LED I have ever seen. It's so bright it almost burns your eyes to look at it and so far it has been unbreakable unlike those POS halogen work lights where we were replacing bulbs every other day.

I'm always amazed at how damn bright the cop and EMS LED lights are from many 100s of yards.
I'm not impressed... at all...
The Finally if really just $8 is OK, but still... LED prices are coming down, and use less power. Really something necessary for people using solar cells and wanting off the grid.

14.5 watts for 800 lumens... Get with the times please. Home depot's Cree 60 watt equivalent have come down to $4.97 each, use 9.5 watts, and output 800 lumens.
And... a 25,000 hour life instead of 14,500.
The $15 floodlight in the article uses 19.5 watts and only 500 lumens:
http://www.vu1corporation.com/produc...964.1399429183
Lumens = 500
115V AC input power: 19.5W
Color Temperature = 3200K
Color Rendering Index > 90+
High Power Factor > .99
Fully linear dimming with ordinary household Triac-based dimmers
Approximately 11,000 hour life
Now the Cree 65 watt equivalents LED available at Home depot use 9.5 watts and output 850 lumens, for $14.97 each, and a 25,000 hour life.
It helps that they flash, and aren't on continuously. They don't have the same heat problems as remaining on.
Nice...
I replaced some PAR38 flood lamps today with the Cree 90 watt equivalent. They were $24.97 each, I have now spent more than $500 in LED lights in the last few weeks. These Cree keep impressing me. I took out the GE FLE26/2/PAR38/XL that were installed about a year ago. The Cree are at least twice as bright since the CFL loses brightness with time. Damn it's bright...
Of the two:
Cree; 18 watts 1500 lumens.
GE; 26 watts 1300 lumens, but the specs say that is initial with 1040 average.
Two links for comparison, for those interested:

http://genet.gelighting.com/LightPro...DUCTCODE=80895
For those wanting a good three-way bulb, Home Depot now has available a 30/60/100 watt equivalent (320/820/1620 lumens) for $24.97.

I found this going to Cree's site:
link: Cree Announces Next-Generation XP LED Delivering 200 Lumens Per Watt
First paragraph:
DURHAM, NC -- Cree, Inc. (Nasdaq: CREE) introduces the XLamp® XP-L LED, the first commercially available single-die LED to achieve breakthrough efficacy of up to 200 lumens per watt (LPW) at 350 mA. Delivering up to 1226 lumens in a 3.45 mm x 3.45 mm package, the game-changing Cree® XLamp XP-L LED enables an immediate performance increase of 50 percent or more as a drop-in upgrade for lighting designs based on Cree’s market-leading XLamp XP-G LEDs.

I've got LED strip lights similar to these going into an office setting next month. I'll let you know how they are.I'm thinking of replacing my kitchen lighting with this:

I'll bet it will be great... at least if it's Cree or Phillips. Cree seems to have the best value in lumens per watt, CRI, and cost per lumen.
The only reason I didn't buy it yesterday is because I'll be replacing a 1' x 4' footprint on a popcorn ceiling. It's just shy of 6" x 40". 4000 lumens for 55 watts... I don't know what the typical 2 tube 40 watt florescent output in lumens, but I'm pretty sure 4000 lumens is fine for my kitchen.
WC living in the stylish lap of luxury no doubt. How about retexturing the place and dropping in some recessed cans?
$10.5 Million For Low Cost LEDs
The new low cost LED funding will be distributed among nine one- to two-year projects in six different states. The total Energy Department contribution adds up to $10.5 million. The recipients will chip in an additional $3.7 million for a total of $13.7 all together.
Here’s the breakdown:
1. In Pennsylvania, Carnegie Mellon University is tasked with “Novel Transparent Phosphor Conversion Matrix with High Thermal Conductivity for Next-Generation Phosphor-Converted LED-based Solid State Lighting.” That’s fancyspeak for impriving heat transfer.
CMU’s work is expected to achieve thermal conductivity of more than five times over conventional LED technology.
That, in turn, is expected to reduce the price of light by up to 50–60%, as meausred in $/klm.
2. Now, here’s a name that should ring a bell. North Carolina’s Cree has been front and center in the LED market, and just last January the company announced a low cost LED breakthrough that beat the Energy Department’s 2020 goal for demonstrating a 200 lumen-per-watt (LPW) LED.
In this round of funding, Cree will focus on modifying conventional LED manufacturing processes, resulting in more economical, compact products.
3. In Ohio, the company Momentive Performance Materials Quartz, Inc. will do something called “Next-Generation LED Package Architectures Enabled by Thermally Conductive Transparent Encapsulants.” The company will tweak LED technology with nanoscale boron nitride, with the goal of producing higher lumen output at the same cost.
4. In New York, the company OLEDWorks, LLC will live up to its name with a project that examines different combinations of components to determine the most efficient way to improve OLED (organic light emitting diode) performance.
5. In California another familiar name, Philips, pops up in the form of Philips Lumileds Lighting Company, LLC. This project, led “High-Voltage LED Light Engine with Integrated Driver,” is aimed at a comprehensive cost reduction.
Philips is casting a wide net with this one. The company aims to reduce the size of the LED package and use fewer components, as well as reducing the weight and size of the housing. If all goes as planned that will also lead to a more simple, less costly fabrication process.
6. In New York, Philips pops up again. This time it’s Philips Research North America, LLC, which will focus specifically on aesthetics, as well as energy efficiency, as applied to patient suites (room + bathroom) in medical facilities.
The expectation is that LEDs can be tailored to contribute patient wellness by providing a more soothing environment, without compromising the lighting needs of the staff.
7. In Maryland there’s a new name on the scene (new to us, at least). A company called Pixelligent Technologies, LLC will use its proprietary sub-10 nm ZrO2 (zirconium oxide) nanocrystals to boost the light extraction efficiency of OLED lighting to the 70 percent level, without compromising other factors.
8. In New Jersey, Princeton University will also work the OLED angle with a project that tackles the efficiency of outcoupling (outcoupling refers to strategies for coaxing light out of OLEDs that is otherwise trapped inside).
Here’s a rather poetic description from the Energy Department:
This project will integrate multiple aspects of outcoupling enhancement within one OLED structure such that the enhancement is greater than the sum of its parts owing to a holistic approach that treats the system as a whole rather than multiple approaches spliced together.
9. In California, the University of of California tackles the OLED cost problem head on by developing a low cost plastic substrate that could replace other expensive components.
U-Cal is aiming its sights high. It expects the cheap subs ute to match the quality of high grade ITO glass, while achieving a 200% improvement on light extraction (ITO glass is a glass substrate tarted up with indium tin oxide).
We Built These Low Cost LEDs!
This is actually Round 9 for the Energy Department’s solid state lighting grants for industry and academic partners, which has already proved instrumental in bringing the cost of LEDs down to a reasonable level. So go ahead and pat yourself on the back, taxpayers.
As a side note, the geographic distribution of the grants illustrates yet another way in which the Obama Administration has been pushing an environmental agenda, despite the efforts of (mostly) Republican state and federal legislators and governors to work in the opposite direction.
Count down that list of Round 9 grants and you’ll see nine industry and academic partners in six different states, four of which have Republican governors notorious for their ties to the fossil energy-leaning lobbying organization ALEC (the American Legislative Exchange Council) and/or the Koch Brothers, who are well known for lobbying on behalf of their extensive fossil energy investments.
Those governors would be Ohio’s John Kasich, Pennsylvania’s Tom Corbett, North Carolina’s Pat McCrory, and New Jersey’s Chris Christie.

Commercial interests should not be given these subsidies. They are competing for the market already, and all this money will do is allow the government to pick winners and losers, making it political.
This is a terrible use of government funding.
but $3T wasted on Iraq-for-BigOil was well spent.
Yesterday, I bought five of the Cree three way bulbs. They are pretty nice. Link in pic:
It wasn't for oil. I guess you would have agreed to it if we did get oil out of it.
