120v 15A AC dimmer?

Does anyone make a 15A dimmer module? I've found 5A dimmers, but I'm looking for something that can dim a bank of incandescent lights. Preferably UL rated, but not necessary. Even better would be a board with 4 or 8 dimmer modules on it.

What about off the shelf Leviton dimmers, or off the shelf Z-wave dimmers? I need to be able to set the dimmer to a specific value (0-255, or 0-100).
