    Default Dimmer Switch

    Can you install a dimmer switch for recessed lights on a switch that is controlled by and outlet.

    Does it need to be a certain type since it is being controlled by a wall outlet or will any dimmer work.

    The type of dimmer has to do with the type of bulbs you are using. Ger the dimmer that meets your bulbs.

    Was going to pick up a 600 Watt Single Pole Dimmer, do you think that would handle things.

    That depends on your total wattage use.

    If power will be coming from a completely switched outlet it would only be capable of dimming/controlling the light if the outlet switch is "on".

    But, if 1/2 of the duplex receptacle is always on, if it is wired per Code, it should work fine, even if the receptacle switch is "off".

    Since the power is coming from a receptacle,which must have a neutral, you can purchase a dimmer that requires a neutral, and is capable of controlling a CFL, LED or incandescent lamp.

    If you want to control a CFL, be sure the dimmer & CFL are capable of dimming...some are not.

    To determine the dimmer wattage required, add up the MAX wattage for each fixture.

    If 4 recessed lights have a max 100watt and you are only using 60 watt bulbs, that dimmer must be rated at more than 400watts so that 600 watt dimmer would be fine. You can usually find the max wattage on the inside of the can by removing the trim from the recessed light. Manufacturers also sometimes include derating factors for multiple dimmers or box volume.
