Flickering lamps, color shifts, and uneven lighting are common faults, which can be corrected by changing the tubes, cleaning the interiors, and re calibrating the light system.

An 18% gray background reduces distractions and color bias, helping in a more accurate assessment.

For a proper color evaluation, ensure cleanliness, use standardized observation conditions, eliminate stray light, and periodically change the lamps.

Replace when the total hours exceed rated life, decrease in brightness, or the color temperature shifts beyond tolerance.

Inaccurate color rendering, mismatched results, and noncompliance with ISO 3664 or ASTM D1729 can occur when there are deviations.

An inappropriate viewing angle may lead to reflections or color shifts in the light. The correct angle of 45 or 0 will provide the real color of the assessment without the distraction of glare.

Standard light sources make sure that the results of color evaluations are comparable and consistent, no matter when and where the assessments are made, or the varying production runs.

Make sure the light sources are calibrated, keep extraneous light sources away, have the correct viewing angles, and handle the samples in a clean and uniform manner.

Common sources like D65, TL84, and CWF mimic daylight, store, home, and fluorescent lighting, and are used to provide conditions for dependable color comparison.

They provide accurate and repeatable assessments of color in various settings for the purpose of avoiding inconsistencies in mismatched items and ensuring steady production or branding.

Standard models are available in a range of sizes, starting from small desktop units which are roughly the size of 60 x 40 x 40 cm, and extending to larger units which are about 120 x 60 x 80 cm based on what you need them for.

In a Pantone light box, the tubes last around 2000 to 3000 hours, after which the brightness and color should be assessed for replacement.

To keep the light box calibrated and to ensure accurate and steady lighting, clean the inside, replace the lamps when needed, check the calibration and record the hours use

Use our 3nh company approved light. Replace all of the same type together and recalibrate to keep consistent color rendering. We usually do not recommend customers to modify it themselves, as this can affect the accuracy of the color and cause unnecessary losses

Testing metamerism helps to identify color matches that look the same but are different in different lighting. This helps in ensuring that materials are of the same quality in all light settings.

Ambient light, heat, and moisture levels should be regulated. The use of colored walls and reflective surfaces should be avoided, as they can damage the assessment of the sample colors visually.

When using a Pantone light box, each sample should be positioned flat and nearby the other samples, but not overlapping. Each one should also be in the middle of the light box, and the surfaces of the light box should be clean and non-reflective.

Pantone light boxes are mainly used for standardized color viewing and color consistency verification across multiple industries to ensure accurate color evaluation under uniform light conditions. Core Application Industries like Textile & Garment Industry, Printing & Packaging Industry, Paint, Ink & Coating Industry, Plastic & Electronic Product Industry, Cosmetics & Food Industry

To ensure a consistent color perception, observers should look at samples at a 45° light angle and 0° viewing angle to reduce glare.

Daylight, store light, home light, and UV fluorescence light sources are included in Pantone light boxes as D65, TL84, CWF, A, and UV.
