The Invincible LED cleanroom luminaire is a precision-engineered lighting solution created specifically for environments where hygiene, durability, and performance are non-negotiable. Designed to withstand the stringent demands of healthcare, pharmaceutical, semiconductor, and food production facilities, Invincible combines robust engineering with cleanroom-ready design. Available in three versatile panel sizes—600 x 600, 1200 x 300, and 1200 x 600 mm—it integrates seamlessly into recessed modular or plasterboard ceilings, providing a consistent and reliable source of illumination in sterile spaces.
Built from a powder-coated sheet steel body and enclosed within a screwless aluminium frame, Invincible ensures a seamless aesthetic that eliminates dirt traps and supports strict hygiene protocols. The luminaire offers a choice of diffusers to suit specific applications: opal polycarbonate, toughened opal glass, or toughened glass with a prismatic optic for glare control. Each diffuser type is engineered to deliver both performance and resilience, with impact protection rated up to IK09 for the polycarbonate version and IK08 for glass. With ingress protection ratings of IP65 at the front and IP54 at the rear, Invincible effectively resists water, dust, and cleaning chemicals. An integrated antibacterial foam seal between frame and body further safeguards the luminaire’s interior, making it an ideal choice for sterile and high-risk environments.
Performance is a cornerstone of Invincible’s design. The luminaire achieves a luminous efficacy of up to 132 lm/W at CRI 80 or up to 117 lm/W at CRI 90, delivering lumen outputs from 3,500 to 14,500 lm. With high-quality LED chipsets, Invincible offers exceptional colour rendering (CRI 80 or CRI 90) and enhanced R9 red performance—crucial in healthcare applications where precise colour differentiation is essential. Its optics ensure visual comfort, with Unified Glare Ratings as low as <19 when specified with microprismatic glass, making it suitable for task-intensive environments such as operating theatres and laboratories.
Certified for reliability, Invincible has been tested by the Fraunhofer Institute and approved for cleanrooms of cleanliness Class 1 to 9 in accordance with DIN EN ISO 14644-1. It also holds HACCP International certification for food production when supplied with the polycarbonate version and complies with EN 60598-2-25 for use in clinical hospital areas. These certifications provide assurance that Invincible meets the highest global standards for safety and hygiene, including compliance with Good Manufacturing Practice (GMP) regulations.
Ease of installation and maintenance is another strength of Invincible. Its screwless frame design allows front access to LED boards and drivers, reducing downtime and simplifying service requirements. The luminaire is equipped with frame retention clips and cover retaining wires to ensure safety during maintenance. Optional suction cup accessories enable easy removal of the diffuser without damaging the housing. Installers benefit from quick connections through a cable entry gland and adjustable plasterboard mounting brackets that are accessible from inside the housing, making setup efficient and reliable.
Invincible is engineered for endurance, with a service life of 72,000 hours at L80 (Ta 25 °C). Emergency options with LiFePO4 batteries, manual test (E3), or DALI-tested drivers (E3D) are available to ensure safety in critical situations. The luminaire also supports dimming via DALI drivers and offers fixed output versions, giving specifiers flexibility to match system requirements. Its operating temperature range of –25 °C to 50 °C (0 °C to 30 °C for emergency models) ensures reliability across diverse environments.
More than just a lighting panel, Invincible is a robust, certified, and versatile solution that bridges performance with hygiene. From its antibacterial foam seal and screwless aluminium frame to its high efficacy LED technology and proven cleanroom certifications, Invincible sets a new standard for lighting in critical environments. It is purpose-built for spaces where resilience, visual comfort, and compliance are paramount, ensuring peace of mind for facility managers, designers, and healthcare professionals alike.
