LED technology using red, green, blue, and white diodes — enables precise Color Temperature control without color filters.
Definition
RGBW refers to a color mixing system consisting of four LED channels: Red, Green, Blue, and White. This combination allows for extended color reproduction and higher light output compared to pure RGB systems.
Practical Application
RGBW LEDs are used in the following areas:
- Color Correction: Adjusting color temperatures between different light sources
- Light Control: Precise control of light intensity and quality
- Effect Design: Creating specific visual atmospheres
- Efficiency Improvement: Reducing post-production effort through precise on-set control
Technical Details
Important technical features:
- Color temperature: Adjustable from 2700K to 6500K
- CRI values between 90-98 depending on the manufacturer
- Dimming from 0-100% without color shift
- DMX-512 control via four separate channels
Practical Tips
- Calibrate the white channel separately for optimal color mixing
- Use a color meter to control color temperature
- Consider thermal management when all channels are fully utilized
- Account for binning tolerances of different batches
Professional Standards
RGBW systems meet broadcast standards for:
- Color consistency according to Rec. 709 and Rec. 2020
- Flicker-free operation from 1200 Hz PWM
- Color temperature stability ±100K over operating duration
- IP54 protection class for outdoor shoots
News
With the Creamsource Vortex 2, RGBW technology reaches new dimensions: The 2x2ft panel delivers 100,000 Lux and features gel emulation algorithms that precisely replicate tungsten and halogen light. Its availability as a battery-powered variant also makes the system interesting for mobile productions.
