The Synergy 21 LED Panel Light, version PRO, is a flat, energy-efficient LED panel with dimensions 622 mm × 622 mm × 12 mm, designed for recessed installation in Odenwald ceilings. With a power consumption of 35 watts and a luminous output of 4200 lumens (Lm/W = 120), it offers high light output at low energy consumption. The light colour is neutral white (4000 Kelvin), suitable for clear, natural lighting in offices, administrative buildings, or retail environments. The colour rendering index (CRI) exceeds 83, ensuring good colour reproduction. The 120-degree beam angle ensures even, broad light distribution without visible light points. The protection class IP40 protects against finger contact and splashing water, making the panel suitable for indoor use. The mechanical protection class IK05 protects against minor mechanical impact. The service life (L80) is 50,000 hours, indicating high operational reliability and low maintenance frequency. The operating temperature ranges from -10 °C to +45 °C, enabling use in various indoor climates. Power supply is via constant current (Constant Current) at 700 mA and 42 ± 2 V/DC. The panel is supplied standard without a power supply unit; required power supplies are available as accessories. The energy efficiency class A+ and consumption of 38.5 kWh/1000h highlight the product’s high efficiency.

Applications

The LED panel is primarily designed for recessed installation in Odenwald ceilings, but with optional mounting accessories, it can also be installed surface-mounted, flush-mounted, suspended, or on walls. Its versatile mounting capability makes it suitable for various indoor lighting scenarios, such as office spaces, retail areas, reception areas, or administrative rooms. The flat design (12 mm height) ensures discreet integration into ceiling structures.

Functions and Equipment in Detail

The panel features a white housing colour and even light distribution via the 120-degree beam angle. The neutral white light colour (4000 K) is ideal for office and administrative spaces, as it is neither too cold nor too warm. The colour rendering (CRI >83) ensures that colours in the illuminated room appear natural. The Unified Glare Rating (UGR <19) ensures low glare, which is important for eye comfort in work environments. Power supply is via constant current (700 mA, 42 ± 2 V/DC), ensuring stable light quality. The panel is dimmable, with dimming functionality depending on the used power supply unit. The warranty is 5 years.

Technology Explained Simply

The lighting technology is based on LEDs powered by a constant current power supply (CC). The constant current supply ensures that light output and colour remain stable, regardless of fluctuations in the power grid. Power supply is via 700 mA at 42 ± 2 V/DC, ensuring efficient and reliable operational safety. The IP40 protection class protects against contact and splashing water, which is sufficient for indoor use. The IK05 protection class protects against minor mechanical impact, such as during cleaning. The service life of 50,000 hours (L80) means that the panel still delivers 80% of its original light output after this time. The operating temperature range of -10 °C to +45 °C allows use in various indoor climates, even in rooms with seasonal temperature fluctuations.

Compatibility and Accessories

The panel is compatible with various power supply units available as accessories. These include CC power supplies from MEAN WELL with different voltage and current ratings, including models with 0–10 V dimmability, Triac dimmability, and DALI dimmability. A PoE power supply (PoE+) is also available, enabling power supply via network cable. Additional accessories include suspension kits (round and II), mounting clips for V3 PRO panel, and a power supply connection kit. An LED cable with integrated steel wire is also available. Combining the panel with an MSR central unit (ALL3419) enables integration into IP-based building automation systems.

Mounting and Installation

Installation is standard in Odenwald ceilings, with cutout dimensions of 605 mm × 605 mm. With optional mounting accessories, surface-mounted, flush-mounted, suspended, or wall-mounted installation is also possible. Installation must be carried out by qualified personnel, and power must be switched off before installation. Mounting accessories such as suspension kits or clips facilitate installation in various configurations.

Operational Advantages

The panel offers high luminous output (4200 lumens) at low energy consumption (35 watts), resulting in energy efficiency class A+. The long service life of 50,000 hours (L80) reduces replacement needs and maintenance costs. The dimmable function allows brightness adjustment according to usage scenarios. Low glare (UGR <19) ensures a comfortable working atmosphere. The versatile mounting capability and compatibility with various power supplies and control systems increase flexibility in planning and installation.
