Which spaces is it designed for?

The PL-A300 is specifically engineered for environments where visual comfort and clarity are paramount. Its design directly addresses the requirements outlined in standards like EN 12464-1 for lighting of workplaces. It is an exemplary choice for architects, lighting designers, and contractors specifying for new builds or retrofits in Class A office spaces, educational institutions, and healthcare settings. The clean, minimalist aesthetic integrates seamlessly into modern architectural designs, providing functional light that contributes to occupant well-being and supports criteria for certifications like WELL and BREEAM.

How does the PL-A300 achieve low-glare UGR<19 for office environments?

The key to the PL-A300's exceptional visual comfort lies in its advanced optical design. Light from the side-mounted LED chips is directed into a high-purity Polymethyl Methacrylate (PMMA) Light Guide Plate (LGP). This LGP, combined with a micro-prismatic diffuser, precisely refracts and distributes light downwards in a controlled 120° beam. This edge-lit method eliminates harsh hot spots and directs light away from high viewing angles, which is the primary cause of glare. This ensures the luminaire meets the strict UGR<19 requirement for spaces with Video Display Terminals (VDTs), reducing eye strain and improving concentration over long periods.

What are the benefits of its ultra-thin profile for installation in grid ceilings?

The luminaire's 9mm thickness is a significant advantage for installers and building managers. This ultra-thin profile allows it to be laid into standard 300x300mm modular grid ceilings (e.g., 15mm or 24mm T-bars) with minimal plenum depth required—often less than 50mm. This is critical in modern constructions where ceiling voids are congested with HVAC ducting, data cabling, and sprinkler systems. For retrofit projects, it simplifies the replacement of bulky fluorescent fixtures without costly ceiling modifications. The lightweight die-cast aluminum frame further ensures quick and secure installation.

Can this panel light be integrated into human-centric lighting schemes?

Absolutely. The PL-A300 is available with a Tunable White option, allowing the Correlated Color Temperature (CCT) to be dynamically adjusted from a warm 2700K to a cool 6500K. When paired with a DALI Type 8 (DT8) driver, the panel can be programmed to follow a circadian rhythm schedule, mimicking the natural changes in daylight throughout the day. This human-centric approach to lighting has been shown to improve occupant alertness, mood, and productivity, making it a valuable feature for forward-thinking offices, schools, and healthcare facilities aiming to enhance occupant well-being.

Installation, control and compliance (DALI-2 / Casambi / 0-10V, CE / RoHS / ErP)

Versatility in installation and control is central to the PL-A300's design. The panel is supplied with an external driver that can be easily placed in the ceiling void.

• Mounting: The primary installation method is recessed lay-in for 300x300mm exposed T-grid ceilings. For solid (plasterboard) ceilings, we offer dedicated surface mount frame kits and adjustable wire suspension kits for a contemporary, floating appearance.
• Control: A range of control options ensures compatibility with any building management system (BMS). Standard units are fixed-output (non-dimmable). Dimmable versions are available with 0-10V, leading/trailing edge (Triac), and DALI-2 protocols. For wireless control, the panel can be integrated with systems like Casambi using a compatible DALI gateway or driver.
• Compliance: The PL-A300 is fully certified for major international markets, carrying CE marking (LVD, EMC, RED), RoHS for hazardous substance restriction, and ErP for compliance with EU ecodesign and energy labelling regulations. Our manufacturing process is certified under ISO 9001:2015, guaranteeing consistent quality and traceability.

Customisation, MOQ and lead time

We specialize in tailoring products to meet specific project requirements.

• Customisation: Beyond standard specifications, we can provide panels with CRI >90 for applications requiring exceptional color accuracy (e.g., galleries, high-end retail), custom CCTs like 5000K, and alternative frame colors based on the RAL classic system. Integrated 3-hour emergency battery backup packs are also available for compliance with safety regulations.
• Minimum Order Quantity (MOQ): The MOQ for standard PL-A300 models is 100 units. For customized versions, the MOQ may vary based on the complexity of the request.
• Lead Time: Our typical lead time for standard orders is 15-20 working days from payment confirmation. Custom projects may require 25-30 working days, depending on component sourcing and production scheduling.

Frequently Asked Questions

Q: What are the available CCT and color rendering options?

A: Standard options are 3000K, 4000K, and 6500K with a CRI of Ra>80. For projects requiring superior color quality or human-centric lighting, we offer Ra>90 versions and a Tunable White option that adjusts from 2700K to 6500K. These custom configurations ensure perfect alignment with your design intent and are available upon request with a minimum order quantity of 100 units.

Q: What is the expected lifespan and warranty for the PL-A300 panel?

A: The PL-A300 is rated for 50,000 hours to L80B10, meaning it will retain at least 80% of its initial lumen output after 50,000 hours of operation. We back this performance with a comprehensive 5-year manufacturer's warranty covering the luminaire and the external driver, providing long-term reliability and peace of mind for your commercial installation.

Q: How is the 300x300mm panel installed?

A: The panel's slim 9mm profile and 1.5 kg weight make it ideal for easy recessed installation in standard 300x300mm T-bar grid ceilings. For solid or plasterboard ceilings, we provide optional surface mount frames and suspension wire kits. The external driver is compact, allowing for flexible placement within the ceiling void, and connects via a simple plug-and-play connector.

Q: Is this LED panel dimmable?

A: Yes, the PL-A300 is highly versatile. While the standard model is non-dimming, we offer multiple dimming protocols to suit any control system. Options include 0-10V analog dimming, DALI-2 digital addressable dimming for smart building integration, and TRIAC (phase-cut) dimming for simpler retrofit projects. We use premium drivers from brands like Tridonic and Mean Well for guaranteed performance.
