The multiLight 4-800 v8 Main extern Keypad is a professional LED colour viewing light for visual colour assessment, colour control and quality assurance. Developed for industries where colour must be evaluated reliably under defined lighting conditions, it supports print, packaging, plastics, coatings, fashion, consumer goods, beauty, food and beverage, medical products, industrial design and manufacturing workflows.
Colour can only be judged accurately when the viewing environment is controlled. A sample that appears correct under office lighting may look warmer, cooler, duller or visibly different under daylight, retail lighting or production conditions. This effect is especially critical when materials, suppliers or production batches need to match across locations. A standardised viewing light helps reduce this uncertainty and creates a more dependable basis for visual colour decisions.
The multiLight 4-800 v8 is designed for professional colour comparison on two-dimensional samples such as print sheets, packaging materials, textile swatches, coated surfaces, labels, plastic samples, proofs, colour standards and production references. Its illuminated area of approximately 70 × 80 cm provides generous space for evaluating medium-sized samples, comparing multiple materials or reviewing colour differences side by side.
The system uses controlled LED illuminants to support assessment under relevant standard light conditions. Available light modes include D50 LED, D65 LED, UV-only and LED B1–B5 options. D50 is widely used in graphic arts and print evaluation, while D65 represents average daylight conditions often used for industrial, textile and product colour assessment. UV-only evaluation can help reveal optical brighteners, fluorescence or material reactions that may not be visible under standard daylight alone.
The ability to switch between illuminants is essential for detecting metamerism. Metamerism occurs when two samples appear to match under one light source but differ under another. This is a common issue in packaging, textiles, plastics, coatings and multi-material product development. By comparing samples under multiple lighting conditions, teams can identify potential colour problems before production approval, shipment or customer presentation.
The v8 system offers professional workflow features such as USB connectivity, dimming, mixed light and programmable light sequences. These functions support flexible viewing scenarios and help colour-critical teams create repeatable assessment routines. Light sequences can be especially useful when samples must be checked systematically under several illuminants during quality-control procedures.
The “Main extern Keypad” configuration includes an external keypad for convenient operation. This supports efficient switching and control during colour review sessions, production checks and supplier evaluations. Instead of interrupting the assessment process, users can move between light conditions in a controlled and practical way.
The compact outside dimensions of approximately 88 × 11.5 × 62 cm make the multiLight 4-800 v8 suitable for studios, labs, print departments, quality-control areas and supplier inspection spaces where a professional viewing system is required but floor or desk space must be used efficiently. It can be integrated into existing colour-management workflows without the footprint of a large cabinet system.
For print and packaging, the viewing light supports the evaluation of proofs, press sheets, cartons, labels, substrates and finishing effects. Designers and printers can compare colour under D50 conditions and review how substrates, inks, coatings and optical brighteners behave under additional illuminants. This helps teams make more informed decisions before approval and production.
For plastics, coatings and industrial manufacturing, the multiLight supports visual comparison between colour standards, production samples and supplier submissions. It helps identify differences caused by pigment, material, surface finish, gloss level, coating, substrate or batch variation. Used alongside instrumental measurement, it provides a visual control step that remains essential for final colour perception.
In fashion, accessories and consumer goods, controlled lighting helps evaluate textiles, trims, packaging, components and materials under consistent conditions. This is important when products are developed through international supply chains and visual colour approval must be shared between design teams, factories, buyers and quality-control departments.
The system is also relevant for beauty, food and beverage, toys, hard home and medical products, where colour can influence perceived quality, safety, category recognition and brand identity. A controlled viewing light helps teams approve colour decisions with greater confidence and reduces the risk of costly misunderstandings caused by unsuitable ambient lighting.
The multiLight 4-800 v8 does not replace professional colour standards, proofs or instrumental measurement. Instead, it strengthens the visual evaluation stage by providing stable, controlled and repeatable illumination. For best results, samples should be assessed using agreed standards, appropriate viewing angles and consistent procedures.
As a professional colour communication tool, the multiLight 4-800 v8 Main extern Keypad supports more reliable visual judgement from design development to production control. It helps teams compare, approve and communicate colour under defined light conditions, making it a valuable solution for colour-critical industries where visual assessment must be both practical and dependable.

FAQ
What is the multiLight 4-800 v8 Main extern Keypad used for?
It is used for professional visual colour assessment, sample comparison, quality control and colour approval under controlled LED lighting conditions.
Which light conditions does the system support?
The system supports D50 LED, D65 LED, UV-only and LED B1–B5 options, with additional workflow functions such as mixed light and light sequences.
Why is controlled lighting important for colour evaluation?
Colour changes depending on illumination. Controlled lighting helps teams evaluate samples consistently and detect problems such as metamerism before approval.
What is metamerism?
Metamerism occurs when two samples match under one light source but look different under another. Multi-illuminant viewing helps reveal this issue.
Which industries can use this viewing light?
It is suitable for print, packaging, plastics, coatings, fashion, textiles, beauty, food and beverage, consumer goods, medical products and manufacturing.
Does the multiLight replace instrumental colour measurement?
No. It supports controlled visual assessment. For full quality control, it can be used alongside spectrophotometers, colour standards, proofs and production samples.
