I bought a Lutron AYCL-153P led dimmer to control a new led fixture which replaced an incandescent fixture. Although the dimmer was installed per Lutron instructions, the on-off toggle's position is inverted, ie. the light is on when the toggle is in the down position and off when the toggle is up. This is opposite the standard convention here in the U.S. Is there any solution other than mounting the dimmer upside down in the wallbox?
