You can remotely turn on/off and dim/brighten a dimmable light fixture with the X10 PRO Soft Start Dimmable Wall Switch. When you turn your light on, the switch's "Soft Start" feature gradually brightens your light within two seconds. When you turn it off, the light gradually fades. This is easier on your eyes as well as the bulbs. In addition to "Soft Start", this wire-in dimmer switch also conveniently remembers your chosen dim level, so when you turn the light off and back on again, it will automatically resume the same brightness.
