PL-S300 Square Surface-Mounted Panel 24W

What is the PL-S300 Square Surface-Mounted Panel and where is it specified?

At XHLWX (led-project-light.com), a Custom Indoor LED Lighting Manufacturer based in China, we engineered the PL-S300 Square Surface-Mounted Panel as a high-performance lighting solution for spaces with solid or inaccessible ceilings. Measuring 300×300×40mm, this 24W luminaire is the ideal choice for retrofitting old fluorescent fixtures or for new builds where a recessed T-bar grid is not available. It delivers clean, uniform illumination perfect for commercial offices, educational facilities, healthcare corridors, and retail back-of-house areas. Its slim 40mm profile and straightforward surface-mount installation make it a versatile and efficient choice for contractors and specifiers in the EU, US, and Middle East markets seeking both performance and aesthetic simplicity.

Photometric and electrical specification

The PL-S300 is designed for versatility and compliance, offering a range of options to meet specific project requirements. Full IES and LDT photometric files are available for import into DIALux or other lighting design software to ensure precise project planning and compliance with local lighting codes.

Which spaces is it designed for?

The PL-S300's design is focused on providing high-quality functional light in common commercial and institutional settings where surface mounting is the only practical installation method.

How can this panel light improve visual comfort in a modern office?

In a modern office environment, achieving a target illuminance of 500 lux on task areas without causing distracting glare is critical. The PL-S300, with its high-transmission PMMA light guide plate, produces a wide 120° beam of diffuse light. This allows for wider spacing between fixtures while maintaining uniformity, and its design enables layouts that comply with UGR<19 requirements as stipulated by the European standard EN 12464-1 for office lighting, reducing eye strain and improving productivity.

What makes this a suitable lighting choice for schools or universities?

For educational facilities, the PL-S300 offers a combination of durability, performance, and safety. The robust die-cast aluminum frame and IK06-rated polycarbonate diffuser can withstand the demands of a busy school environment. Its flicker-free driver options are essential for creating a conducive learning atmosphere, preventing headaches and visual fatigue. Furthermore, its high efficacy of over 110 lm/W translates into significant energy savings for large campuses, and the 50,000-hour rated lifespan drastically reduces maintenance cycles.

Is this panel appropriate for back-of-house retail or circulation areas?

Yes, absolutely. In non-customer-facing areas like stock rooms, staff corridors, and preparation zones, the primary requirements are reliability, efficiency, and ease of installation. The PL-S300 excels here. Its simple surface-mount kit allows for rapid deployment on concrete or plasterboard ceilings without complex structural work. It provides bright, even light (2640 lumens) for safety and task visibility, while its 5-year warranty ensures long-term, maintenance-free operation, making it a cost-effective choice for facility managers.

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

Installation is streamlined via a four-piece aluminum frame that is screwed directly onto the ceiling surface. The panel then securely slides or clips into place. The fixture is compatible with a wide range of control systems to meet modern building energy codes and user preferences. Options include standard on/off (non-dimmable), 0-10V analog dimming, Triac dimming, and fully addressable DALI-2 control for integration into building management systems (BMS). Wireless control via Casambi Bluetooth mesh is also available for projects requiring flexible zoning without new control wiring. The product is fully certified with CE, RoHS, and ErP for the European market, and FCC for the United States, ensuring compliance and peace of mind.

Customisation, MOQ and lead time

While the standard model is a 24W, 4000K, Ra>80, non-dimmable panel in a white (RAL9016) finish, we offer extensive customisation to meet project-specific needs. Options include specifying CCT from 2700K to 6500K, upgrading to a high CRI of Ra>90, implementing Tunable White functionality, or integrating DALI-2 or 0-10V dimmable drivers. Housing finishes can be specified to any RAL color. Our typical Minimum Order Quantity (MOQ) for custom configurations is 50 units. Standard production lead time is approximately 15-25 working days from order confirmation to dispatch from our Shenzhen facility.

Frequently Asked Questions

Q: What is the standard warranty and rated lifespan for this panel?

A: The PL-S300 panel comes with a comprehensive 5-year warranty covering the entire luminaire, including the driver and LEDs. It has a rated operational lifespan of 50,000 hours to L80B10, meaning that after 50,000 hours of use, the fixture will still maintain at least 80% of its initial lumen output, with only 10% of a large sample group degrading further. This ensures long-term, reliable performance.

Q: Can this panel be used for emergency lighting?

A: Yes, the PL-S300 can be configured with an integrated emergency lighting kit. This option includes a dedicated battery pack and charging circuit that provides 3 hours of emergency illumination at a reduced output, typically around 300-400 lumens. This ensures compliance with building safety codes for safe egress during a power outage. Please specify this requirement when ordering so we can include the EM-kit version.

Q: What are the available CCT and CRI options?

A: Our standard configuration is a highly efficient 4000K CCT with a Color Rendering Index (CRI) of Ra >80, suitable for most commercial applications. For projects requiring warmer or cooler tones, we offer custom CCTs from 2700K to 6500K. A high-fidelity CRI >90 option is also available, which is ideal for retail spaces, art galleries, or healthcare facilities where accurate color representation is critical.

Q: How does the surface mount frame work during installation?

A: The surface mount installation is very straightforward. The kit consists of a 4-piece aluminum frame. An installer first assembles three sides of the frame and screws this U-shape assembly directly to the ceiling surface. The LED panel is then slid into the frame. Finally, the fourth side of the frame is attached with screws to lock the panel securely in place. The entire process takes approximately 10-15 minutes per fixture.
