TILO CC120-W-1 Suspended Standard Light Booth

Overview

The TILO CC120-W-1 Suspended Standard Light Booth is an engineered color evaluation system designed for precise visual color assessment under controlled, standardized illumination conditions. It operates on the fundamental principle that human color perception is highly dependent on spectral power distribution (SPD) of incident light — a phenomenon known as metamerism. Without consistent lighting, identical physical samples may appear discordant across viewing environments, leading to misjudgments in color matching, quality control, and customer acceptance. This booth addresses that variability by delivering calibrated, high-CRI illumination conforming to international standard illuminants including D65 (simulated daylight at 6500 K), D50 (printing industry reference at 5000 K), TL84 (cool white fluorescent, common in retail), and CWF (cool white fluorescent used in North American commercial settings). Its suspended configuration enables ergonomic integration into production lines, QC labs, and prepress studios where ceiling-mounted installation minimizes floor space usage while ensuring uniform vertical illumination over the full viewing surface.

Key Features

• Suspended structural design with integrated mounting hardware for ceiling installation — eliminates footprint constraints and supports workflow continuity in high-throughput environments.
• Four independently switchable, factory-calibrated light sources (D65, D50, TL84, CWF) with simultaneous multi-source activation capability for metamerism detection and cross-illuminant comparison.
• High-color-fidelity fluorescent lamps with average CRI (Ra) ≥95 for D65/D50 and ≥90 for TL84/CWF — compliant with ISO 3664:2009 requirements for graphic technology viewing conditions.
• Uniform illuminance ≥1000 lux at 300 mm working distance across the entire 1200 × 600 mm viewing area — verified per ASTM D1729 Annex A1 procedures.
• Digital timer function activated per light source selection — supports standardized exposure duration protocols and lamp warm-up tracking (optimal chromatic stability achieved after 30 min).
• Modular lamp access via two quick-release white cap screws — facilitates rapid, tool-free lamp replacement without disassembly of the enclosure or optical diffuser.

Sample Compatibility & Compliance

The CC120-W-1 accommodates flat, rigid, and semi-flexible substrates up to 1200 mm wide and 600 mm deep, including printed sheets, coated papers, textiles, plastics, automotive trim, and painted panels. Its viewing chamber geometry and matte black interior minimize stray reflections and glare, satisfying the geometric and photometric criteria outlined in ISO 3664:2009 (Graphic technology — Viewing conditions) and DIN 6173-2 (Colorimetric viewing cabinets). The unit is certified for use in laboratories operating under GLP-compliant workflows and supports audit-ready documentation when paired with TILO’s optional calibration logbook and lamp replacement tracking protocol. While not FDA 21 CFR Part 11–validated out-of-the-box, its deterministic lamp switching logic and non-volatile timer enable traceable operation within regulated manufacturing environments where visual inspection forms part of release criteria.

Software & Data Management

This model operates as a standalone hardware platform with no embedded software or network interface. All operational parameters are managed manually via tactile switches and analog timer feedback. Lamp usage time is tracked per channel via built-in mechanical timers — data is non-digital but fully auditable through manual logging. For enterprises requiring electronic recordkeeping, TILO provides a companion Excel-based Lamp Usage Tracker template (v2.1), compatible with ISO/IEC 17025 internal audit schedules. No firmware updates, cloud connectivity, or remote diagnostics are supported — ensuring electromagnetic compatibility (EMC) stability in electrically noisy production facilities and eliminating cybersecurity attack surfaces inherent in connected instrumentation.

Applications

• Prepress proof verification against ISO 12647-2 standards using D50 illumination.
• Final product color release testing in textile dye houses under TL84 and D65 side-by-side comparison.
• Automotive interior component evaluation per OEM specifications requiring CWF + D65 metamerism checks.
• Pharmaceutical packaging QC where label color consistency must be validated across multiple lighting environments prior to batch release.
• Educational use in color science laboratories for teaching SPD-dependent perceptual phenomena and observer variability modeling.
• Third-party inspection agencies performing accredited visual assessments per ISO/IEC 17025 scope clauses referencing ASTM D1729 and ISO 3664.

FAQ

What is the recommended warm-up time before conducting critical color evaluations?
A minimum of 30 minutes is required for all lamps to stabilize in chromaticity (x, y coordinates) and luminance output, per ISO 3664:2009 Clause 5.3.1.
How often should the lamps be replaced to maintain compliance?
Lamps must be replaced after 2000–3000 hours of cumulative operation — documented via the built-in timer or external log — to ensure CRI and CCT remain within tolerance limits specified in DIN 6173-2 Annex B.
Can this booth be used for evaluating metallic or pearlescent coatings?
Yes, provided samples are positioned perpendicular to the primary illumination axis and assessed under D65 only; angular dependence requires supplementary gonioscopic instrumentation beyond this booth’s capability.
Is the viewing surface UV-filtered?
No — the standard configuration includes no UV-emitting components nor UV-blocking filters; optional UV-A (365 nm) and UV-B (312 nm) modules are available separately for fluorescence assessment applications.
Does the unit include photometric certification documentation?
Each shipment includes a factory-issued Certificate of Conformance listing measured illuminance (lux), CRI (Ra), and correlated color temperature (CCT) for each installed lamp set, traceable to NIM (China National Institute of Metrology) standards.
