Product Overview

The document details specifications and options for the ARVA series of pendant lamps featuring acrylic glass diffusers with fine matt finish and lens optics. These lamps are designed for ceiling mounting with adjustable height via steel cords.

Mounting and Housing

• Ceiling mounting using black cables (diameter 5 mm or 7 mm) with steel cords, length 2000 mm, height adjustable.
• Lamp housings are made of diecast aluminium with passive cooling, available in metallic grey (RAL 9006), white satin matt (RAL 9003), black satin matt (RAL 9005), or bright chrome-plated finishes.

Optics and Light Source

• Two optic types: acrylic glass diffuser with fine matt finish and high-quality glass lens optics with 60° beam angle.
• LEDs integrated with Color Rendering Index (CRI) 85 or 95, available in color temperatures 2700 K, 3000 K, and 4000 K.
• Service life approximately 50,000 hours at 70% luminous flux.

Electrical and Protection Specifications

• Operating device: PS 230 V/50 Hz, with constant current options (350 mA or 500 mA) depending on model.
• Lamp protection class I and protection level IP 40.
• Energy efficiency class ranges from A to A++, with built-in LED lamps that are non-replaceable.

Product Variants and Technical Data

The lamps come in various wattages, lumen outputs, and Kelvin temperatures, organized by housing color and dimming capability (standard ON/OFF or dimmable DALI):

• Power options: 6 W, 15 W, 27 W, and 49 W.
• Lumen output: Ranges from 450 lm to 4510 lm depending on model and color temperature.
• Color temperatures: 2700 K, 3000 K, 4000 K.
• Dimensions and weights: Weights vary from 1.1 kg to 5.1 kg; taper diameters and distances for lens optics are specified.

Accessories

• Baldachins with integrated operating devices available in multiple finishes matching lamp housings.
• Mounting rails compatible with the METRON lighting system, available in anodised aluminium, white satin matt, or black satin matt finishes.
• Cavity adapters in steel with matching finishes for pendant lights; operating devices ordered separately.

Photometric Data

Included are polar diagrams and luminous intensity distributions (cd/1000 lm) for different lamp models, indicating beam angles and light distribution patterns at C0/C180 and C90/C270 planes.

Critical Information and Best Practices

• Height adjustment via steel cords allows flexible installation.
• LED lamps are integrated and non-replaceable; ensure correct selection at purchase.
• DALI dimmable versions provide enhanced lighting control.
• Operating devices must be ordered separately for some models, especially those requiring constant current drivers.
• Passive cooling design ensures thermal management without additional components.
