A LED 3 way would be interesting but it would probably be too expensive to build in 3 seperate power supplies for the 3 sections, each would need a seperate one. There probably isn't as much call for a 3 way bulb compaired to a single.
I checked HD again and the Phillips and Cree are still on sale. If you put in zip code 02816 and select Coventry #4279 store you get:
Philips 60W Equivalent Soft White (2700K) A19 Dimmable LED Light Bulb
$4.97 / each
LINK (This one looks like the mini flood light bulb picture that was posted earlier)
and
Cree 60W Equivalent Soft White (2700K) A19 Dimmable LED Light Bulb
$7.97 / each
LINKThe Warwick RI store shows a higher price online.
I guess HD knows us Rhode Island Swamp Yankees ain't gonna pay $13 for a bulb. ;)
