Five years since I posted the above. That LED lamp bulb is not available any more. Eventually, I was able to get some from Amazon but even those ended up out of stock.
Lately I've been buying my LED bulbs from Walmart. Just the MR 16 for uplights and the G4 bi-pins for path lights.
I noticed they changed the bulb design and now there's a "Shatter Resistant" icon on the packaging - which leads me to believe people were dropping the old ones on the floor and they were breaking - or maybe they broke from the heat.
I also recently tried the 10w equivalents and were very impressed with their effectiveness for the path lights. Still using 20W M^ 16's for the uplights.
