I dunno about the large scale bit, it depends on the deal you can get. As for "long haul": If I left every light in my 2 bedroom apartment on 24/7, the portion of my electricity bill corresponding to the cost of the lights would only reach $50,000 by 2138. So if I make it to 150, I could rest easy knowing that I saved myself some money...except that utilities are included in my rent. I imagine if one lived in California, they payoff time would be shorter.
On the other hand, compact fluorescent bulbs are 35 times cheaper, and 50%+ more efficient than LED bulbs (Even using coloured LEDs. Using white LEDs, fluorescents are 3 times more efficient) Some company has said that by 2005 it will be producing white LEDs that are as efficient as compact fluorescents...
Until then, however, compact flurescents are the way to go for saving power OR money.

LCDs are a totally different technology. They lag because, well, jeez, I explained this once before but it slips my mind (It's early here! Give me credit! Please!). Basically, it has to do with the fact you're asking a material (crystals) to twist and bend when power is applied; then you take the power off them (or reverse it) to try to force them back to their original position. This takes time.

The compact flourescent technology causes no visible flicker, is smaller than the old magnetic ballast (which operated at the frequency of house wiring, 60Hz), and improved efficiency overall, losing less energy to heat in the ballast.

Japanese style lanterns make particularly lovely LED lamps. Quick, cheap and easy to make if you just want a little mood lighting without the fire risk of the real thing. Or try the old punch some holes in a coffee can trick.
Soon the lure of the light switch called though and I returned to using conventional electric lamps and conventional oil lamps. It was an interesting experiment though. I still keep a couple of LED paper lanterns on poles about the place for fun.
If I were going to build off the grid (like that boat or the cabin in Montana) I wouldn't have any hesitation about lighting it with a combination of LEDs and oil (never put your eggs all in one basket).

Thank you. Thank you very much.
You saved money. Good for you. Most people in your position live a bit above their means and end up with all sorts of payments they can't make when the job goes away. You're ahead of the game already and show evidence of the sort of thinking that might make it off the grid.
An Adobe hut in Mexico is a lovely way to live. I spent a few months in a couple back in the late 60s. $20,000 should last you about 20 years if you live a bit American. You can live off the interest damn near forever if you aculturate. Yes, it really is that cheap to live there. Adobde is absolutely delightful to live in in the appropriate enviroment (desert}. Hell itself in the wrong one (rainforest). I've tried both. I enjoy it for a time, the desert is lovely, but I'm from the northeast mountains and start longing for trees and meadows after awhile. A bit of ocean doesn't hurt either.
Books. Lessee. There really aren't too many good ones. Most of them are written by "back to nature" types. There's a difference between back to nature and off the grid. One is a philosophy (generally propounded by city folk), the other is just living. Just living, on the whole, works better as a philosophy of living than a "philosophy of living" does. The trick is to adopt the proper mindset and adapt yourself to the life, rather than trying to force the way of life into some preconcieved notion of "the way things should be."
On the whole "nature" doesn't give a shit about "the way things should be" and just goes about her business as usual. If you get squashed along the way, well, that's natural.
The people who actually live like this don't normally write books about it. It's just normal life to them, why write about it?
But there are some exceptions and a handful of books not overtly intended for off the grid living that can be invaluable.
First off there's Walden of course, if only for inspiration, but there's a fair amount of very practical advice on living in there. Remember, the whole point was an experiment in living. Throw in Life Without Principle. If you read this and say "Yes! That's what life is all about" you'll probably have a shot at living off the grid. Anybody contemplating any sort of nonconventional living ought to read these. They're both available on the web.
One of the most valuable books you can possibly own if you're going to build any sort of shelter, from a shed to a mansion on the edge of town is Rex Robert's "Your Engineered House." If you've read my posts much you've heard me mention this one before. It's a must. Written in a conversational style that you can read like a novel and illustrated with his own crude pen drawings this book is a marvel. He covers everything in this book and will leave you wiser about home building than an entire library shelf full of other books.
***BUY THIS BOOK***
Did I make myself clear?
It's out of print. You'll pay at least triple it's original cover price to acquire it used (I'm not the only one who reveres this book. Last time I looked there were copies available on Amazon), maybe double that if you want a really clean copy with dustjacket. Pay whatever you have to. Diamonds aren't cheap.
Square Foot Gardening. How to grow the most food, the easiest. Forget everything you know about farming. Conventional farming is medieval ideas about how to grow food en mass for the masses. You want modern ideas about how to just grow food for you. This one will get you started. Supplement with any book about container gardening that catches your eye.
I'm afraid I've never seen a single book beyond the technique of growing food off the grid that was worth a crap though. Honestly, they're all pretty much garbage. You can cherry pick them for bits of info though

No, I've never met a "back to nature" person who PETA would want to have much to do with. PETA isn't much for slaughtering livingstock and keeping milk cows and hunting. PETA are the very antithesis of the back to nature folk and can only exist in cities. The Amish are religious Luddites, not back to nature people, perfectly civilized and like it that way and very effective capitalists. They tend to think of the back to nature folk as city loons, and they're right.
The back to nature folk are sort of a cross between hippies, survivalists and new agers.
They're not only anticapitalist, they're antimoney and often antitrade. They have some vague romantic notions about "being one" with nature and try live totally and completely self sufficiently, by farming mostly, with some hunting and gathering thrown in, and making absolutely everything themselves, eschewing everything they perceive as technology (without any apparent realization that farming itself is a technology, as is a house and a candle and a steel hoe). They can't quite make up their minds about whether they want to be hermits or communists. They virtually all come from cities (country folk think of them as city loons, and they're right) and they virtually all fail.
You can do mountain man/hermit just fine if you want. A good knife and you're set. A gun is really, really nice to have though, and matches make life easier. Every one I've known also has some product to sell now and again, even if it's only racoon hides. But then a good knife is actually pretty high technology. A gun is even higher. You're not going make your own of either out in the woods or on your little farm thingy. You have to buy them.
The only back to nature folk I've ever met who "made it" were the ones that eventually realized that the way you make a living from a farm was by being a farmer. You grow crops in excess of your needs. You sell them and then you spend the money on things you need. Things that other people make in excess while you're farming. Things like oil lamps, plough blades, maybe a radio, or a knife, or an electric generator, or, gasp, modern medicine ( 'cause those natural herbs just didn't seem to do the job after all on little Johnny's appendicitis).
Because farming is a technology of civilization. Go figure.
Thoreau sold crops and taught school. For money. To buy things with. Things he couldn't make himself. Like flour (remember I said don't grow grain?) paper and ink. His family owned a factory in town that made pencils.
I only know of one way to go completely back to nature that works. Full blown late stone age living. It can be done. There are certainly at least a few people living like that right now, although fewer every year (The knife and the T-shirt seem to have made it nearly everywhere now). I've tried it as an experiment (just because it's the sort of thing I do sometimes for fun. Really). I can do it. Others less suited for it than I have managed with a little extra to work with. Selkirk, for instance. It isn't what most people would call "fun." Oh yeah, don't get sick.

Especially considering that LEDS dont "break", but fade. If not electrocuted, they become slowly dimmer. The 100.000h usually means the time where they are only at 50% or so output. So even a long time after that, it would still produce light, even if its not a lot.

Cost is coming down (slowly) and eventually LEDs will be reasonable replacements for ordinary lightbulbs, with similar light characteristics except for added features such as optional color control and the like.
The Vos Pad is silly because like so many posters have pointed out, it's as uninhabitable as the star trek apartment that other guy built. Plus, it looks incredibly gay with those colors. Just an immensely complex concept piece demonstrating how not to use LED light fixtures. The Vos Pad appears dark and spooky, a movie set rather than a home. And the light beams coming from the floor will be incredibly annoying. But all this don't mean the technology itself is invalid.
LED lit homes can conveivably be every bit as practical as ordinary types. LEDs can be fitted into whole new kinds of fixtures that wouldn't be possible to make with conventional technologies. The LEDs are so versatile they can be built into anything and arranged in any pattern or configuration imaginable. Thin panels or stripes of light could be fitted under shelves or hidden in the ceiling so as to provide advanced discrete lighting without the hassle of bulb replacement.
As a test project a little while I ago I drew up a fancy model for a dream bathroom in a 3D program, accurately picturing discreet LED illumination with color accents and proper work surface brightness and no nasty point lightsources burning out retinas.
The render engine used was precise enough using photon maps, global illumination and caustics, that you could get a reasonable estimate of the number of LEDs on any given spec you need to light a room properly. You can pretty much go in with a virtual light meter and measure how much light hits any given simulated surface point and add more lights until you have the desired brightness. (As a photographer I have a nice digital spot lightmeter, and was able to calibrate the model using a handful of Nichia superbright white LEDs for reference.)
Turns out you need hundreds of LEDs to get an equivalent brightness to just a few 25 watt halogens. But if I had the cash to splash I'd definitely consider it for my new apartment!

We live far enough north (Puget Sound region) where the short days and extended periods of cloud cover during the winter do indeed have a noticeable affect on my moods.
Considering that I grew up in California, which averages 328 sunny days per year, this came as no great surprise.
What I ended up doing for our home was installing full-spectrum flourescent tubes in the flourescent fixtures, and bright halogens in my work area. Both have done wonders for my mood in the winter months.
Unless someone has come up with a full-spectrum LED, I don't think this kind of lighting is going to see wide adoption outside of perpetually sun-drenched areas, and then only as a "Gee Whiz" item because of the high cost.

I asked my other half, she wouldn't use the bathroom for all the rice in China. Point-blank no way. "How could I work out my makeup in that light?" was her first question.
I am thinking about the kitchen. How do I get a meal looking right in those ghastly hues? How can I enjoy a steak when it will look like a Quake gib under that light?
So while this is a noteworthy effort, it may have set the cause of LED lighting back by years... (kidding, okay? I'm pretty sure other architects and designers will see the advantages and adopt them pretty quickly...)
Which is sad because the idea of using LEDs to light a living space (or indeed a workspace) is sorely needed in view of the air pollution that our thirst for light and convenience creates.
I read somewhere that a 100W consumed for a year produces a cupful and a half of pollutants in that year. (I.e. collect all the pollutants and scrunch 'em together, bingo, 1 1/2 cups of waste...)
That means that for every 100W lightbulb in your place, which stays on for an average of a quarter of a day or so, over a quarter of a cup of crap per year... The average home has seven lightbulbs, that's over two cups of pollution per house per year.
If you could reduce the amount of power required to produce the same amount of light to around a fifth or less, you'd reduce that contribution to pollution due to light from two cups to a quarter cup.
That has to be worth going for...
