How Sample Testing Identifies Color Variation in Hybrid Moving Heads

Evaluating color consistency in hybrid moving head production means comparing fixtures under controlled, repeatable conditions. Tests can reveal visible differences in RGBW output, preset colors, color temperature, dimming response, and beam coverage. The available specifications describe a 24 × 20 W RGBW LED wash fixture with preset modes and linear CTO from 3000 K to 9000 K. They do not include measured sample results or allowable production tolerances.

How to Compare Fixture Samples

Begin by setting each unit to the same RGBW values, color preset, CTO level, dimming curve, and output level. Keep the operating position and viewing conditions consistent, then compare hue, brightness, and coverage side by side. Repeat the observations at several points across the dimming range to see whether any differences change as output decreases.

The LEDARC 2420P is specified with 24 four-in-one RGBW LEDs rated at 20 W each, 24 acrylic lenses, a 25-degree beam angle, and a 30-degree field angle. These figures describe the fixture’s design; they are not evidence of measured color uniformity. A useful test log can record each setting and note visible hue, intensity, or distribution differences without implying an unprovided pass limit.

Settings and Checks to Include

• Match RGBW values and preset modes across all samples before comparing color output.
• Check selected CTO settings within the stated linear range of 3000 K to 9000 K.
• Observe color and brightness at multiple output levels using the relevant dimming curve. The fixture lists four curves and 0–100% linear dimming.
• Assess coverage across the beam and field, and verify flicker-free operation in the intended TV or film setup, as specified in the product information.
• Repeat observations after functional checks and burn-in, and document whether any visible variation remains.

Production Quality and Application Context

Color Imagination describes a quality process that includes incoming-material inspection, checks during production, optical performance verification, final inspection, 100% functional testing, and burn-in testing. The company also lists CE and ISO certificates for stage-light assembly and related management activities. The supplied information does not confirm that each certificate applies specifically to this model, nor does it publish color-shift acceptance criteria.

The fixture’s listed control methods include DMX512, RDM, master-slave, sound-activated, and automatic operation. Running samples in the control mode intended for the installation helps separate differences in the operating setup from variation between fixtures. Listed applications include architectural lighting, theme parks, plant lighting, and large-scale live concerts.

Specifications and What Sample Tests Can Show

Frequently Asked Questions

Are measured color differences between production samples published?

No. The available material lists product features and describes quality-control steps, but it does not provide sample-test results, color-difference measurements, or production tolerances.

Which settings should be matched during testing?

Use the same RGBW values, preset, CTO setting, dimming level, and dimming curve for every fixture. The stated CTO range is 3000 K to 9000 K, and four dimming curves are listed.

What quality checks does Color Imagination describe?

The company reports incoming-material inspection, in-process quality control, final product inspection, functional testing, burn-in, and safety inspection before shipment.

Recommendations

For a meaningful production comparison, test multiple samples using identical controls and viewing conditions. Review RGBW mixing, CTO behavior, dimming, flicker, and optical coverage, then record observations before and after burn-in. Unless a model-specific tolerance is available, treat these findings as comparative observations rather than formal pass-or-fail results. For technical support, contact jack@color-imagination.com.
