I got these off Amazon because of the reviews. Not a lick of trouble with them, and color is real close to the original incandescent heat machines. Inverter fan doesn't even kick on with every light running in the place.

http://www.amazon.com/gp/product/B00EDFM6R8All running great after 4 months full timing. Something of note - the wedge bases on the LEDs is a little thicker that the el cheapos that were in there. Takes a fair amount of pressure to pop them in first time. Be careful, don't bend the paddle on the led light, and you'll be fine. I suspect some of the flickering complaints are as a result of folks manhandling the LEDs on install.
I also did a MaxxAir II smoke vent cover last November here

In case you haven't noticed, I love Amazon. Dont get me wrong, i love Tweety's too, just sometimes they dont get there on price. Am not affiliated with either BTW. This has been the year of the upgrades for me. New 5er, new truck, and commenced to changing parts.
ETA: fix links
