## Long description

Synergy21 S21-LED-J00248 Square 35 W is a surface-mounted LED panel light that provides neutral white illumination for commercial and residential interiors. With dimensions of 622×622×12 mm and a low-profile design, this panel offers uniform light distribution suitable for suspended ceilings or direct surface mounting. The fixture operates from a DC input of 42 V, consumes 35 W and produces an output close to 4200 lm, delivering efficient general lighting for offices, corridors and retail areas while meeting an energy efficiency class equivalent to the former A+ rating. The specified operating temperature range is -10 to 45 °C.
Advantages
The LED panel delivers neutral white light at 4000 K with a high luminous efficacy of approximately 120 lm/W, combining energy efficiency with consistent brightness. Its thin profile and surface-mounted format simplify installation where recessed mounting is not possible. A rated lifetime of around 35,000 hours and an estimated number of switch cycles up to 50,000 reduce maintenance frequency and total cost of ownership. The panel also provides a wide beam angle (up to 120°) and a Color Rendering Index (CRI) of 83 suitable for general-purpose interior illumination.
Suitable for
Office workspaces and meeting rooms
Corridors, stairwells and common areas
Retail sales floors and display zones
Classrooms and training facilities
Residential rooms requiring even general lighting

How to use
Before installation, ensure power is disconnected and confirm compatibility with a 42 V DC supply. Mount the panel on a clean, level surface using the appropriate brackets or fixing hardware for surface-mounted fixtures; follow local electrical codes and manufacturer guidance for wiring connections. Connect the DC input to the approved driver or power supply that matches the panel's voltage requirements. After wiring and securing the panel, restore power and verify uniform illumination and correct operation. For best results, avoid mounting near excessive heat sources and allow adequate ventilation around the fixture.
Usage recommendations
Use the panel in indoor locations within the specified temperature range and with a stable DC 42 V power source. For workspace installations, position panels to minimize glare and ensure even light distribution across work surfaces. Consider grouping panels with consistent color temperature to maintain visual uniformity. Regularly inspect mounting and wiring every 1–2 years and replace the fixture when luminous output noticeably declines near the end of the rated lifetime.
