The RC4 Series 3 LumenDimM4 is a miniature battery-powered 4-channel wireless DMX dimmer ideal for for LEDs, lamps, motors in small props, costumes, and more that operates on the CMRX platform. The LumenDimM4 combines the best RC4 Wireless Harmonized Design features with a built-in genuine LumenRadio CRMX radio transceiver. The result is an easy to use, reliable, feature-filled DMX dimmer that gives users an outstanding wireless RDM (remote device management) experience that includes multiple dimmer curves and PWM frequencies.

Barely larger than a matchbox, the LumenDimM4 — the M stands for miniature — features super-smooth LED dimming, high-power halogen dimming and hobby servo-motor control, which are accomplished with four dimmers. In fact, a single LumenDimM4 could be used to construct a complete miniature moving light.

Harmonized Design is part of the RC4 Wireless product experience, and the LumenDimM4 is no different. It features:

The LumenDimM4 has four channels, which makes it ideal for red-green-blue (RGB), red-green-blue-white (RGBW) and red-green-blue-amber (RGBA) LED color-mixing. The RC4 Wireless Hue/Saturation/Level (HSL) Color Controller delivers best-in-class color consistency over the entire dimming range, by ensuring precise primary color ratios even at very low dimmer levels using 16-bit (65,536 step) dimming. Unlike single-channel DMX control of color mix 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, which means precise—and easy—color mixing.

Four dimmer outputs also provide an optimal experience with the RC4 Wireless Flkr Effects Engine. Using DMX channels for control, dynamic animated effects are easily and quickly created using the LumenDimM4. The RC4 Wireless Flkr Effects Engine is not a canned effect generator; this is a tool the enables designers to create unique looks to suit their specific need. These original effects can also be stored and recalled, and a saved effect can be enabled on power-up. This provides a means of creating and using custom effects without an external DMX controller — perfect for standalone displays in retail, trade shows, and more.

Learn more about how to use the LumenDimM4 at the RC4 Knowledge Base.

The RC4 Series 3 LumenDimM4, and all RC4 Series 3 dimmers, provides 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 LumenDimM4 to be used as a wired dimmer.  Either wireless or wired, a comprehensive RDM implementation includes E1.37 dimmer configuration parameters, numerous status sensors (voltage, temperature, current), and each individual dimmer appears as an RDM sub-device.

Screw terminals are provided for connection of the power supply (+/-DC IN) and load devices (+/-DimA, +/-DimB, +/-DimC, +/-DimD). The supply powers both the internal electronics and the connected loads. Dimmers switch on the negative side of the circuit, ideal for common-anode (common positive) LED tape.  Dimmer output voltage is precisely the DC power input voltage with no appreciable losses within the 16A total power handling limit of the device

The DMX miniplug port can be used with a range of RC4 DMX cables, including 3-pin and 5-pin male and female XLR adaptors. The most common adaptor is the RC4DMX5FA with 5-pin female XLR connector.

6 years and still going
Color: Blackout, Color: Blackout
Owned for 6 years and still going strong. Worn daily, including showers. The only time I take it off is to sleep. The face is scratched up and some buttons worn smooth (I wear it on the inside of my wrist). A few tiny cracks are beginning to form on one of the wristband pieces. Replaced the battery after about 3 years. It has three alarms and I use them regularly. You can choose to set each alarm for daily, weekdays, or weekends. I also use the timer a lot. Indiglo gets used every morning and many evenings. You can disable modes that you never use, so you only see what you want. I never use chronograph, so I have that disabled. Incredible watch.

The watch of our era
Color: Blackout
Bought this ‘used’ but looks like only the box had some ‘damage’ but the watch was perfectly brand new. I’ve been wearing a timex Ironman watch since my tenth birthday. I’ve served in the Marine corps and wore one while on tour. I’ve worn them snorkeling and diving. I’m a mechanic and have worn it on my belt loop while working, and depending what I’m doing I’ll leave it on. I wear it in the shower, the pool, beach, kayaking, skydiving, mudding, surfing, fishing, shooting, and while relaxing in my recliner. I’ve only had one battery die, and it was easily replaced. This is the watch of our era. Stop reading this review and buy one!

Very dim
Color: Black/Yellow Accent
This was a gift for our son. The watch functions well, but I returned it because the screen was very hard to read.

Proud of my watch.
Color: G5885-silver-red, Color: G5885-silver-red
I purchased two of these and I am pleased so far.I was able to resize the band without any problems.They look good and I’ve received a few unsolicited compliments.IMHO they are well worth the 35 bucks or so I spent on them.Heck two of my buddies wearing r.l.x’s noticed them right off the bat.I just smiled and said thank you very much. P.s.I could buy and sell my two friends many times over so didn’t bother me when they ask me the price.Proud of the good watch for the money.
