The kit includes the dimmer switch and one Philips Hue white LED bulb. With the Philips Hue wireless dimming kit, you can turn any standard light fixture into a dimming fixture right out of the box with no wiring needed. Simply screw in the Hue LED bulb and place the switch nearby. You can affix it to a nearby wall with screws or the adhesive tape on the back of the switch or let it rest on a table.
