I recently picked up a couple Philips "Slimstyle 10.5W (60W Repl.)" Dimmable
bulbs #9290002707. These bulbs work fine in both X10 situations described above.
On the X10 dimming wall switch, they turn on and off fine, and dim fine with
incandescent bulbs also on the circuit, although the incandescents are pretty
dim before the LEDs dim much. On the other lamp with an appliance module, they
turn completely off when turned off, whereas the Cree bulb put out significant
light, like a nite light, when off.

These philips bulbs look a little wierd, as they are relatively flat, with a
flat panel in the middle of a LED tube.

Mine were $4 at HD, but that could be a Seattle City Light subsidized price, as
the Cree bulbs were previously.
