Here's great news for anyone who has been waiting for LED lightbulb prices to drop from "oh my goodness" to "oh good, I can buy one". Best Buy's in-house brand is now offering the warm spectrum, Insignia LED bulb, both online and in-stores. Shaped just like a traditional incandescent, the bulb uses 75% less energy than a traditional bulb, with a product life of more than 22 years; the 60 watt equivalent 800 Lumens model costs just $1.57 to light up per year (three hours per day). A few notes after trying one below...
Plugged into a table lamp our review unit illuminated with a light somewhere inbetween the warmth of a regular soft white filament bulb with a hint of bluer light characteristic of LEDs (the 800 Lumen bulb is rated as 3000K). Not a 100% match, but only noticeable because we compared them side by side, before and after using our remnant 60 watt incandescent kept around for these bulb comparisons.
Additionally, the Insignia bulb turned on instantly, working with our lamp's dimmer control without issue (some users on Best Buy's review site noted flickering, but this could be due to the quality of a home's power lines, something we've learned while living in an pre-1930's unit with plenty of plugged-in devices), and seems ideal for secondary table or corner lighting instead of as a reading light source. Now if they can only offer a sub-$20/bulb 100-watt equivalent, then I'd switch out all of our CFLs and convert our home into a fully LED illuminated apartment!

I would also like reasonably priced LED bulbs equivalent to 100 watt incandescent bulbs. My old eyes need strong lights!!! I have a fixture over my table which requires 5 - 100 watt bulbs. At $40-50 a bulb for LED replacements, I will continue to use my GE 100 bulbs for as long as they hold out.
I still haven't found any LEDs that can be used in fully-enclosed indoor fixtures. Has anyone else?
Why can't any LED be used in a fully enclosed fixture? The heat output of any LED bulb is orders of magnitude less than that of an incandescent....
uummmm I'm sitting here looking at my 60W LED lightbulb that I got at ( everyone make a face ) Walmart for $6.87. It looks just like a regular lightbulb except instead of a filliment it has a sort of illuminated core and there's a grey band between the glass and the metal screw in part, giving the thing a pleasant 'steampunky' look. If I wanted a 100W it would have cost me an extra two bucks. Last week they were all marked down a buck or two depending on the wattage. This works out to about half of what they want at BestBuy. Just saying.
LEDs are little semi-conductor chips about the size of a pin head and do create heat as the electricity flows throug (between 1-3 watts per chip). They need to have this heat carried away otherwise they will crack and die. The most common cooling method is to use a metal heat sink to draw out the heat and transfer it to the air. Enclosed fixtures keep the air in, letting the heat build up until the heat sink can't keep the LED cool.
The light fixture manufacturers will need to design an enclosed fixture that allows the heat to be dissipated. They already do that with "LED from the ground up" fixtures (namely outdoor area lights and desk lights). Just give them time.
@Hilton would love to see a link to the 60W LED bulb you mention (even if it's Wal-Mart), as I can't seem to hunt down on their site at anywhere near the price you're quoting. Was it a limited offer price, because I'm not seeing anything in-store or online at the price you've mentioned. If available, that would be a fantastic option for everyone to upgrade.
I've bought a few of these and had good results:

@gregory I can't find an online link either but they are in the store ( Manchester NH ) and I've seen them for at least a year because I've been buying up the regular lightbulbs for my brother to use in his trouble lights at work. They are there and if you happen to live anywhere near me I'll gladly go there with you AND buy you coffee later and yack about interior design. Sorry that I can't be of any more help.
I think I could make my fortune on a web site that properly compares all these crazy new lights. Finding the right shape, color, brightness, dimmer behavior, and so on is a serious headache. I've been attempting to replace track lights with LEDs and they all have a funky issue or another.
We're at the point where our next bulb purchase will probably buy LEDs even if they're expensive. NONE of the CFLs we've had in our house in the last 4.5 years have lasted more than 2 years (all claimed to last 7 years). 4-5 different brands, so it isn't a fluke. The American public got hosed on CFLs. As much as I dislike Walmart, if they have LED bulbs as inexpensive as Hilton got his, I'm going there.
Does anyone know of a compact (3.5" in length) LED, equal to 60 watts & dimmable? These are for wall sconces & I need 24! Thanks.
LED "white light" is an optical illusion. Any other light source (incandescent, daylight, even chemical lights) produce a broad swath of colour frequencies which we interpret as white light. Sometimes a "white light" will be cheated a bit and have more of some frequencies than others, so if the light has slightly more towards the blue/violet end of the spectrum then it will be cold light, and more towards the red end will be warmer. Basically, though, they emit pretty well all the frequencies in the human visual spectrum at approximately the same amounts, which then bounce off of stuff or get absorbed into stuff and our eyes use that input of which ones get to us after bouncing (or not) to determine colour and all the other information that goes along with that.
LED white light doesn't have all those frequencies. It has a spike in the middle of our red spectrum, a spike in the middle of green, and a spike in the middle of blue. Since each frequency is hitting our eye in roughly balanced amounts we end up interpreting it as white, but there are Massive gaps. That's why LED lights leave everything looking vaguely dead, and also why it's confusingly difficult to "focus" under them. Our eyes are trying to pick up all the information they're used to being able to see with white light, and incapable of communicating to us what it is that's missing. You end up getting a similar experience to that of being in a photographic dark room (with that one narrow frequency-band of red light) where it's difficult to focus one's eyes and make out what you're looking
I'm a theatrical lighting designer, which means that I work with light tone and colour filters constantly, and I can only hope that this recent craze for LEDs passes soon.
Nice to see there are more higher output LEDs available now but 800 lumens is only equivalent to a 60W incandescent - way too low for some uses in my home.
I prefer the ~3,000K colour temp of halogens vs incandescent in my home. I use LEDs on my car and they are typically 5,000-5,500K to match the xenon headlights.
I got a pair of 800 lumen halogen bulbs for the bedroom months ago from IKEA and they no longer sell them now. They were designed with a clear glass surround like a traditional incandescent bulb but inside there is a halogen bulb. IKEA are stripping out their filament bulbs but their LED selections seem to stop at 400-500 lumen output.
Anyways I have CFL/LED compatible dimmers for the bedroom fixtures so when I need to replace them there may be some cheaper options. Will check out WalMart to see what they have.
Actually there are fully enclosed rated LEDs now, I have some and bought them here: http://store.earthled.com/collections/led-light-bulbs-suitable-for-enclosed-fixtures-fully-enclosed-fixture-rated-led-light-bulbs
