Our take on the Universal MRFA-3LD-URC

by Ralph Graves

Now you can enjoy custom lighting control without custom installation. All you need is this Universal dimmer and compatible Universal MX-450 remote (available separately). With a press of a button you can dim or brighten your table lamp.

Setup is easy. Just plug the dimmer into the wall, and then your table lamp into the dimmer. To program different lighting levels, press and hold the dimmer. It's that simple.

You can add additional dimmers and control them with the MX450 remote. Set an entire room's lighting just the way you want it with a single command.

Overview: The MRFA-3LD-URC is an incandescent/halogen dimmer with built-in radio frequency (RF) receiver. URC Lighting Control by Lutron offers a simple, cost effective way to control the lighting in your home entertainment area.

Light Fixture Compatibility: The MRFA-3LD-URC RF Lamp Dimmer is designed to work with incandescent and halogen lighting up to 300 watts. Do not exceed maximum load rating of dimmer (300W). Do not use where total wattage is under 25 watts.

Note:  Do not use to control fluorescent lighting fixtures or compact fluorescent lamps. Do not use the RF Lamp Dimmer to control table lamps with built-in dimmers, or touch sensitive lamps.

Tap Switch: The MRFA-3LD-URC features a Tap Switch which offers multiple functions.

  • Tap once for On/Off
  • Tap twice quickly for lighting to adjust rapidly to full On.
  • Press and hold to fade the lighting with a 70-second delay.

Dimming Rocker: There are two push-buttons that let you dim and brighten your connected lamp.

LEDs: Seven tiny LEDs indicate your connected lamp's light level. These LED indicators can be set to glow softly at night as a night light, when the connected lamp is turned off.

Remote Compatible: The RF Lamp Dimmer is also compatible with select Universal remote controls (such as the 554MX450, sold separately), so you can use the same remote control to dim the lights and control your home theater system.

Note: Using the Universal MX-450 remote control you can store preset lighting levels for movie night.

AC Power: The MRFA-3LD-URC RF Lamp Dimmer module features an attached 6' AC power cord terminated by a 2-prong AC plug which plugs into an AC wall socket (120V-60Hz). The same 2-prong AC plug has a 2-prong AC socket on the other side to plug in your compatible incandescent/halogen lamp.
