Key Features

  • X-fade White Light: Crossfading our Candlelight diode (2000k) and Daylight diode (6000k) mixing a balanced variable color spectrum. With independent 2000-6000° diodes we give a full range of high quality broad spectrum light and allow color saturation without the muddy effects of RGB derived white light. Includes Kelvin presets at 2000° (2800°) 3200° 4000° (5000°) 5600° 6000°
  • RGB: A rainbow of color at your finger tips. With a full 360° palette for vibrant fully saturated color or mixed with X-fade white light for soft beautiful pastels. Includes color presets for Blue, Cyan, Green, Yellow, Orange, Red, Magenta, Purple.
  • Low Profile Shape: Easy to hide when space is at a minimum, the slender linear lamps can be mounted tight against a wall or ceiling.
  • Expandable and Scalable: Stack them in a column to create large LED panels of any size, or end to end for long linear lighting sources. Create geometric patterns and 3D structures or spell out words the options are endless.
  • Control Panel: No need to pull out your phone or have a Wi-Fi network. The Rainbow comes equipped with an on-board control panel allowing you to set Intensity, CCT, Saturation, Hue, FX and much more.
  • FX: Onboard effects with adjustable parameters. Including Fire, Police Light, Short Circuit, Paparazzi, Strobe and Rainbow Color Scroll.
  • DMX Port: With DMX I/O, the Rainbow can be wired for DMX data control and passed through for chaining multiple lamps together.
  • Wireless Control: Equipped standard with Lumen Radio CRMX wireless transceivers, Rainbow lamps can be controlled remotely via compatible transmitters.
  • Lead / Follow Mode: Set a master lamp and control all others. Rainbow LED lamps can be set to send or receive commands to and from any other Rainbow making it easy to change the settings of any multi lamp fixture or rig without dialling each lamp.
  • Energy Efficiency: The Rainbow Lamps vastly outperform traditional Quartz, Halogen and HMI lighting sources in luminous output to power consumption ratio.
  • Self Ballasted AC Input: Run a line, RGB-X Rainbow Lamps use 100-265VAC (World Power) via Neutrik True1 connect and do not require troublesome external ballasts, power supplies or data boxes.
  • DC Battery option: Grab a battery, RGB-X Rainbow Lamps can run off of 10-26 VDC via locking 2.1mm x 5.5 barrel connector.
