Product Information

The highest power LumenDim device, delivering up to 42A across 4 dimmer channels — 500W at 12V, 1000W at 24V. Perfect for wireless lighting on turntables and set pieces of any size. Provides all RC4 Series 3 features with the power to go big.

Each LumenDim4 purchase comes with oneĀ 2dBi antennaĀ and one set ofĀ Anderson Connectors.

The RC4 Series 3 LumenDim4 is a battery-powered 4-channel wireless DMX dimmer on the CRMX platform for use with LEDs, lamps, costumes, props, motors and more. It combines the bestĀ RC4 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 andĀ PWM frequencies. The LumenDim4 give users super-smooth LED dimming, high-power halogen dimming and hobby servo-motor control.

All RC4 LumenDim devices include a genuine LumenRadio TiMo CRMX2 radio receiver. Easily assign any DMX channel and dimmer curve to any dimmer with the press of a single button usingĀ RC4 OneTouchā„¢, or useĀ Remote Device Management (RDM) via wired or wireless connection.

  • PWM frequenciesĀ Optimizations for power handling, smoothest resolution, eliminating artifacts in video, and eliminating noise in audio systems.
  • Tungsten lamp dimming
  • Servo motor control
  • RC4 Digital Persistence™ A carefully engineered thermal model makes LEDs fade up and down like incandescent and halogen lamps.
  • HSL Color ControllerĀ Choose to use Hue/Saturation/Level (brightness) control of color if desired.
  • RC4 ColorMatch™ Match color palettes and white-balance different LED sources from different manufacturers.
  • RC4 Flkr Effects Engine™ Create personalized visual effects, including fire, welding spark, and much more.
  • Remote Device Management (RDM)Ā The DMX standard for device configuration, including E1.37 dimmer control extensions.
  • RC4 CodeLoaderĀ Update firmware to add features.Ā  Since 2014, more than 10 new features have been added at no cost to users!

The LumenDim4 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. TheĀ RC4 Hue/Saturation/Level (HSL) Color ControllerĀ 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 theĀ RC4 Wireless FLKR Effects Engineā„¢. Using DMX channels for control, dynamic animated effects are easily and quickly created using the LumenDim4. The Flkr Effects Engine is not a canned effects 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 stand alone displays in retail, trade shows, and more.

The LumenDim4 includes 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 LumenDim4 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.

The DMX mini-plug port can be used with a range of RC4 DMX cables, including 3-pin and 5-pin male and female XLR adapters. The most common adapter is theĀ RC4 DMX5FA with 5-pin female XLR connector.

Hi
First orders great and really nice it's from a fellow event sparks
the cutters really good as we can give it to anyone to cut tape off cables rather than cut cables with a Stanley kinfe
Plus your tuff bags are a great price
Looking forward to more purchases soon

Hi John,

Thanks so much for taking the time to leave such a lovely review!

It's always great to hear from a fellow event sparks! We're really pleased you're happy with your first order, especially the cable cutters and Tuff Bags.

Completely agree about the cutters too! Anything that helps protect cables from an overenthusiastic Stanley knife is a winner in our books!

We really appreciate you supporting a fellow industry professional and our small business. Looking forward to helping you out with your next order!

All the best,

Matilda UK Tour Lighting department has used Going Dark to not only purchase show consumables, but also used their label printing service. Dom was great at taking my original label design and incorporating that for printing over 150 hard plastic label cards.

I can highly recommend for show supplies or label printing.

Hi Glen,

Thank you so much for the fantastic review and recommendation!

It was a pleasure supporting the Matilda UK Tour Lighting Department with both your show consumables and custom label printing.

It's always great to get involved in projects beyond simply supplying products, and we're really pleased we could take your original designs and turn them into something practical for the tour.

Thanks again for trusting Going Dark with the work and for supporting our small business. We really appreciate it and look forward to working with you on future productions!

Fantastic to have a shop dedicated to the sort of specialised equipment we use in the live events world.

Hi Dylan,

Thank you so much for the fantastic review!

That's exactly why we started Going Dark Shop! Having worked in the live events industry ourselves, we know how difficult it can sometimes be to source the specialist kit and consumables we use every day, so we wanted to create a shop that really understands the needs of our industry.

We're always looking to expand our range and bring more useful products under one roof.

Thanks again for your support. It really means a lot, and we look forward to helping you out again soon!
