The manufacturer says they are 10.5 watts each and "dimmable to 5 percent with most standard incandescent dimmers. "

Most common dimmers are rated at 600 watts.

I used the DIva's that are designed for LED/CFLs. Worked like a charm.

The manufacturer shows the light having no problems with conventional Triac incandescent dimmers.

All these units have switching (and well into tens of kilohertz at least) AC to DC power supplies.

It is NOT very hard to design the power supplies to tolerate the voltage waveform of a Triac dimmer.

Why use a more expensive part than even the manufacturer says will work?

I was looking at the diva series but prefer the toggle switch over the paddle. I plan to call Cree tomorrow but will ask here because of the knowledge. Will the lutron 600w incandescent switch operate the same in a toggle and paddle styles?

"Will the lutron 600w incandescent switch operate the same in a toggle and paddle styles?"

Same construction, a conventional Thyristor dimmer.
