The RC4 LumenDimM2micro is a 2-channel CRMX wireless DMX dimmer for LEDs, lamps, and motors in small props, costumes, and more. The inconspicuous circuit-board assembly can easily be hidden in the smallest spaces, even in hair and fabrics.

TWO versions available:

  • with internal antenna
  • with external antenna (included)

Delivery time: 5 - 7 days


The RC4 Series 3 LumenDimM2micro is — by far — the smallest wireless DMX dimmer on earth.

It is a battery-powered 2-channel wireless DMX dimmer for small props, costumes, and more.  A genuine LumenRadio TiMo radio transceiver is built-in, providing an outstanding wireless RDM (remote device management) experience.

Smooth LED dimming

It includes a built-in radio receiver and two pulse-width-modulation dimmers.  With super-smooth LED dimming, halogen dimming, hobby servo-motor control, HSL color control, a sophisticated effects engine, and DMX input/output, it is a powerhouse in a tiny package.

Like all RC4 LumenDim devices, it includes a built-in radio receiver and uses RC4 OneTouch™ for easy assignment of any DMX channel and dimmer curve to any dimmer with a single press of a single button.  Device configuration can also be done with Remote Device Management (RDM).

Two channels are ideal for hybrid-white LED color-mixing, to transition between different color temperatures of white.  The RC4 Hue/Saturation/Level (HSL) Color Controller delivers best-in-class color consistency over the entire dimming range, ensuring precise mix ratios even at very low dimmer levels using 16-bit (65,536 step) dimming.  Unlike single-channel DMX control of color from a console, which is limited to 256 steps and becomes heavily quantized at low levels, the RC4 HSL Color Controller maintains high ratiometric precision throughout the dimming range.  In addition, RC4 ColorMatch™ makes it easy to calibrate intensity between two light sources.

The warmth of incandescent lighting has long been favored by lighting designers, and for good reason; natural filament persistence ensures smooth fades even when control resolution is relatively coarse.  RC4 Digital Persistence™ brings this same pleasing smoothness to LED dimming, with a range of  eight persistence periods emulating a variety of halogen lamp sizes.  LEDs have never looked this good.

Many pulse-width-modulation (PWM) dimmers look good to the human eye, but produce banding, blinking, and other anomalies when used with video cameras. For this reason, all RC4 Series 3 dimmers provide multiple PWM frequencies.  Low frequencies are most efficient, ideal for high-wattage incandescent lighting. Mid frequencies improve the appearance of LEDs by eliminating visible strobing in human peripheral vision.  High frequencies eliminate video artifacts.  And finally, supersonic PWM frequencies, though least efficient for power handling, provide PWM dimming without audio interference when used near microphones and electrified musical instruments.

Wired DMX

The RC4 DMX miniplug port can used with a range of DMX adaptors, including 3-pin and 5-pin male and female XLR connectors.  The most common adaptor is the RC4DMX5FA with 5-pin female XLR connector, making the LumenDimM2micro the smallest wireless dimmer and the smallest wireless DMX receiver available.

The LumenDimM2micro, and all RC4 Series 3 dimmers, provide a wired DMX data port.  In most cases this port is used to output data to nearby fixtures including fog machines, moving lights, and projector dousers.  The DMX port can also be configured as a DMX input, allowing the LumenDimM2micro to be used as a wired dimmer.  In this mode, a comprehensive RDM implementation includes E1.37 dimmer configuration parameters, voltage monitoring, and each dimmer appears as a separate RDM sub-device.

A small Amp MTA-100 6-pin connector is provided for connection of power supply and dimmer outputs.  Each device is provided with one connector with 6″ (15cm) leads.  Input DC powers both the internal electronics and the connected loads. Dimmers switch on the negative side of the circuit, ideal for common-anode (common positive) LEDs and LED tape.  Dimmer output voltage is precisely the DC power input voltage with no appreciable losses within the 10A peak power handling limit of the device.  Continuous running power is limited to 6A due to the safety rating of the Amp MTA-100 connector pins.


Device configuration can also be done with Remote Device Management (RDM).
