I'm glad to see LED fixtures finally becoming mainstream in the local big box stores. Purpose built fixtures make more sense than trying to make LED's look and work like A19 lamps. Here's an example of the fixture I saw at the local Home Depot today:

I'll post more photos/findings once I get it hooked up.

I too had the offset issue, the 2nd screw went direct into the ceiling joist. Oddly the smaller boxes seem more common than the larger ones in ceiling use.

There are 50 point LED's (possibly cree's devices) on the board.  The large black chip is most likely the a chip whose function is sensing dimming on the incoming power signal and translating that to the equivalent on/off duty cycle for the LED's.  Just a couple of small surface mount chip caps.. so no electrolytics to fail.  But heat is a silent killer for most IC's... if the fixture is hot - U1 is gets my second vote for the most failures.  First goes to the movistor.  The LED's are likely to suffer a "fading" effect and slowly become less effective. Four or five years from now you might notice a difference if you compare it against an identical fixture.  But then anyone expect a CFL last five years - with lots of use, dimming, and turning on/off....

At $30 I expect it to last, hopefully they stand behind their warranty for 5yrs if it doesn't. If it fails after 5yrs LED tech will be fully mature by then and newer better fixtures will be out. Fixtures designed for LED from the start have a lumen/watt advantage since they can take advantage of the native directional properties of LED. Fixtures also have more thermal management options compared to A19 retrofit laps, and as you said heat is the enemy of the electronics/driver circuit.

IMHO the best is yet to come for LED fixtures, I'm sure they are working on things we haven't even though of. Fixtures is what will revolutionize the LED lighting industry, not A19 replacements...

Generally based upon the needed requirements, The mode of selection will be depended. In these aspects, We must consider the high quality of LED strips which will help us to give more brightness while compared to the normal one.
