NIIMBOT N1/B18 Labels - Surface PET 13 × 35mm (90 Labels) Glow in the Dark / Luminous

These 13 × 35 mm labels provide passive visibility in low-light conditions while maintaining the durability of PET material. They are designed for applications where identification must remain visible without relying on external lighting. Key Features Glow-in-the-dark PET construction — Photoluminescent treatment provides passive visibility after exposure to light, supporting identification in low-light or blackout conditions. 13 × 35 mm format — Compact rectangular size suitable for constrained surfaces such as panels, storage items, and small equipment. 90 labels per roll — Reduced roll count reflects specialised material and format. Wide temperature rating (-30°C to 120°C) — Maintains structural integrity across storage, transport, and operational environments. Durable PET substrate — Resistant to moisture, handling, and abrasion compared to paper-based labels. Thermal transfer compatible — Requires ribbon-based printing for stable, long-life printed content. Gap label format — Supports consistent label positioning and repeatability during printing. Application Context — Low-Light Identification Glow-in-the-dark labels operate by storing light energy and re-emitting it in darker conditions. This provides a passive identification method where powered lighting is unavailable or unreliable. Typical use cases include electrical panels, storage systems, and safety-related identification where visibility must be maintained without user interaction. In normal lighting conditions, the label functions as a standard PET label. Under low-light conditions, the photoluminescent layer becomes visible, improving recognition without requiring an external light source. The effectiveness of the glow depends on prior exposure to light and the surrounding darkness level. Due to the compact format, the label is best used for short identifiers such as codes, circuit references, or directional markers. Ribbon colour should be selected to ensure sufficient contrast for daytime readability, as low-contrast combinations will reduce usability before glow conditions are active. The PET substrate ensures that the label maintains adhesion and structure under handling, moisture exposure, and temperature variation, while the treated surface provides the additional low-light visibility function. A compact label format combining durable PET construction with passive glow visibility for identification in low-light environments.
