Ceiling/wall LED panel Synergy21 S21-LED-J00259, square 622×622 mm, 35 W, warm white, surface-mounted

Synergy21 S21-LED-J00259 is a square surface-mounted LED panel designed for ceiling or wall installation. With dimensions of 622×622×12 mm and a power consumption of 35 W from a DC supply, this panel delivers warm white illumination suitable for evenly lighting offices, corridors, retail spaces and residential rooms. The single-unit panel provides diffuse general lighting with a neutral-optics design that integrates into suspended or fixed ceilings and onto flat wall surfaces.

Advantages

The panel produces warm white light at 3000 K with a luminous flux of approximately 4200 lm, offering energy-efficient general illumination. A CRI of 83 ensures acceptable color rendering for most interior applications. The wide beam angle up to 120° distributes light evenly across the room while the rated lifetime of 35,000 hours and up to 50,000 switch cycles reduce maintenance frequency. Its low-profile 12 mm thickness and surface-mounted design simplify installation where recessed mounting is not available.

Suitable for

• Office open-plan areas and individual workstations
• Corridors, stairwells and common areas in commercial buildings
• Retail spaces, showrooms and small shops requiring uniform ambient lighting
• Residential living rooms, kitchens and hallways as general ambient lighting

How to use

Prepare a flat, stable mounting surface on a ceiling or wall and ensure the DC power source matches the panel's input requirements. Turn off mains power before installation. Fix the panel using appropriate screws and anchors for the substrate, route the DC supply cable to the panel connection, and secure all electrical connections following local electrical codes. After connecting power, restore supply and verify uniform light output. For integration into continuous layouts, position panels with regular spacing to achieve even illumination.

Usage recommendations

Use the Synergy21 panel with a compatible DC driver that provides stable output within the panel's specified input range. Avoid mounting in locations with direct exposure to water or high ambient humidity unless additional protection is applied. For tasks requiring high color fidelity, consider supplemental task lighting or fixtures with higher CRI. Schedule periodic visual inspections and clean the diffuser with a soft, dry or slightly damp cloth to maintain light quality.
