These bulbs are pretty cool! My local store has them on sale for around $11 now. I found a review here comparing it to a plain old CFL.
I was quietly predicting that 2012 would be the breakthrough year for LED bulbs for the general public with price/performance becoming such that people will start buying them in much larger quantities. Perhaps I have predicted too early as price of some of this newer technology is still sky high and I have not seen very many good LED bulbs at the $10 price point. It has been almost a year since I bought these bulbs.
The warm white version of this bulb seems to be on perpetual sale for $11-$12 over the last few months. I'm not comfortable with its reliability after hearing feedback from others. The first one I bought died in a day. A reviewer on youtube had 2 of three of his quit. A few other folks lost a couple as well. A 20-40% failure rate is not that great to me and scares off public acceptance of LED bulbs. For me, the premature failure rate of CFL bulbs is less than 5%.

have really good luck, very low early failure rate for CFLs, and LEDs so far
excepting that one LOA showehead bulb (running but dimly...)

Dave was running his LOA outdoors in the Canadian winter. The LEDs never got hot until summer. Still 2 winters and a summer is pretty good for 5 mm LEDs.
We've been collecting Goniospectroradiometer data, Integrating Sphere data, and thermal images of several LED bulbs. The plan is compile the data and correlate that with CAD models and simulations to generate IES ray sets and IGES files along with reports about how each bulb is made and performs. We'll make them available for download at somepoint in the near future although I can't say when. Not because it's a secret but because making the website isn't my thing.
Same LED that is in the new 60W equivalent or it least that's what it looks like to me: http://i1083.photobucket.com/albums/j390/Harold_LF/P1010250.jpg
I would hope that reputable suppliers would be able to provide that data. That has been my experience even from secondary Asian suppliers, at least photometrics. If they want EnergyStar they must have LM79 data.
