The tempLED RayDown commercial LED downlight is a versatile lighting solution ideal for sanitary facilities, providing reliable protection with its IP54 rating. Its application range extends to workplaces, offices, social rooms, changing rooms, and circulation areas such as corridors and hallways, where consistent and pleasant lighting is essential. Available in two sizes and wattages, the luminaire ensures broad light distribution combined with a frosted light field cover, producing an evenly diffused and comfortable light environment. The modular design supports optional DALI-2 or TRIAC dimming, allowing flexible control over light levels, while installation is simplified through SnapIn spring clamps for quick and secure mounting.
The lighting properties of the tempLED RayDown ensure high-quality performance. It offers an initial luminous flux ranging from 960 to 2,400 lumens, with a luminous flux tolerance of ±10 percent, and achieves a system efficiency of up to 120 lumens per watt. The color output is consistent, with a color temperature of 4,000 kelvins, a color rendering index (CRI) above 80, and a color consistency of less than 6 SDCM. The symmetrical beam angle of 100 degrees ensures broad coverage, while photobiological safety complies with IEC/TR 62778. The luminaire maintains low flicker characteristics, with a compact flicker degree (CFD) of 1 percent, stroboscopic visibility measurement (SVM) of 0.001, and short-time flicker (Pst LM) of 0.007, making it suitable for sensitive environments.
Electrotechnically, the tempLED RayDown operates on AC power between 220 and 240 volts at a frequency of 50/60 hertz. System performance is available in 8-watt and 20-watt options, with a tolerance of ±10 percent. The luminaire maintains a power factor above 0.90 and includes overvoltage protection, overheating protection, and temperature monitoring to ensure operational safety. Total harmonic distortion remains below 18 percent, and the temperature classification (ATEX) is T5, with a maximum Tc temperature of +90 degrees Celsius. The luminaire contains a light source rated for energy efficiency class E.
Mounting is straightforward, with standard recessed ceiling installation, while optional features include DALI-2 or TRIAC dimming, a minimum dimming level of 20 percent, constant lumen output (CLO), an emergency light module, and human-centric lighting on request. The housing is designed for ambient temperatures from –20 to +45 degrees Celsius, providing reliable IP54 ingress protection in installed conditions and impact resistance rated IK05. Electrical protection class II ensures safety, while the die-cast aluminum housing, natural steel spring clips, and impact-resistant opaque polycarbonate cover plate combine durability with a refined appearance. The luminaire housing is finished in traffic white according to RAL 9016 with a powder coating for additional protection. The supply connection uses 2x 0.50 mm² cables, with 30-centimeter lengths from the power supply and between the power supply and luminaire, terminating in open cable ends. The luminaire supports 2-pole AC wiring or 2-pole AC with 2 DALI control lines.
Certifications include ENEC (in preparation) and conformity to CE and RoHS standards. The expected lifespan is approximately 100,000 hours at L70B10C1 and 50,000 hours at L90B10C1, with a five-year full warranty and a ten-year spare parts guarantee, ensuring a secure long-term investment. The delivery package includes the luminaire, power supply, and two spring clips for ceiling installation, providing a complete solution for commercial and sanitary applications.
