Does the Lutron Maestro C.L Dimmer Exist?
Give it about a month and it will be out.  Our company just had a meeting with our Lutron representative and it should be out real soon.  He did not give a date but I think they were waiting for Lightfair to make it official.

EDIT
I talked with the factory rep today and he said orders (on distributors level) are being accepted now and the C•L should be available for consumers in July.
