How Sample Testing Identifies Color Variation in Hybrid Moving Heads

Comparing production samples under controlled conditions can show whether hybrid moving head fixtures produce consistent RGBW colors, color temperatures, dimming transitions, and beam coverage. The available specifications describe the LEDARC 2420P as a 24 × 20 W RGBW wash fixture with preset color options and linear CTO adjustment from 3000 K to 9000 K. They do not include measured sample comparisons or defined color tolerances.

What to Check During Sample Testing

For a meaningful comparison, operate each fixture with identical control values and conditions. Match the RGBW mix, preset, CTO setting, dimming curve, intensity, and fixture position, then compare hue, brightness, and coverage. Repeat the inspection at multiple dimming levels to identify changes that may only become apparent as output decreases.

The LEDARC 2420P is specified with 80 preset modes, 62 preset background color options, four dimming curves, and 0–100% linear dimming. These features provide several settings to examine, but the published information does not state how closely individual production units match one another.

Interpreting the Fixture Specifications

Color and optical output

The stated light source consists of 24 four-in-one RGBW LEDs rated at 20 W each. The fixture also lists 24 acrylic lenses, a 25-degree beam angle, and a 30-degree field angle. These are design specifications rather than evidence of measured color uniformity. During a sample review, record the selected mode and settings alongside any visible differences in color or coverage, without applying a pass limit that the manufacturer has not published.

Color temperature and dimming

Test selected points across the linear CTO range of 3000 K to 9000 K, and compare fixtures at the same settings. Check several dimming levels and, where relevant, each of the four available dimming curves. This can reveal whether a color difference appears only at particular intensities or during a specific control configuration.

Production Checks and Operating Conditions

Color Imagination states that its quality process includes incoming-material inspection, in-process checks, optical performance verification, final product inspection, 100% functional testing, and burn-in testing. Repeating sample observations after functional checks and burn-in can help establish whether a visible difference remains. No product-specific color-shift acceptance threshold is provided.

The company also lists CE and ISO certificates for stage-light assembly and related management activities. The available information does not confirm that every listed certificate applies specifically to the LEDARC 2420P.

The fixture is presented for applications including architectural lighting, theme parks, plant lighting, and large live concerts. Its control modes include DMX512, RDM, master-slave, sound activation, and automatic operation. Testing with the intended control method helps separate differences between fixtures from changes caused by the operating setup. The product information also describes flicker-free operation for broadcast television and film, which can be checked in the intended camera environment.

Product Data and Sample-Test Observations

Frequently Asked Questions

Are measured color differences between production samples published?

No. The available material describes product features and quality procedures but does not provide sample-test measurements, color-difference values, or production tolerances.

Which settings should be matched before comparing fixtures?

Use the same RGBW values, preset mode, CTO setting, dimming level, and dimming curve. The fixture lists four dimming curves and a linear CTO range of 3000 K to 9000 K.

What quality checks does Color Imagination describe?

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

Conclusion

To assess color consistency in hybrid moving head production, compare samples using matched controls, inspect RGBW mixing and CTO settings, and note changes across the dimming range. Record observations before and after burn-in where possible. Unless a product-specific tolerance is available, treat the findings as comparative observations rather than formal pass-or-fail results.
