Overview of REBA Aluminium Profile Lighting Systems

The document provides a comprehensive technical overview of the REBA range of aluminium profile LED lighting systems, including models such as REBA 50, REBA 65, and their variants (e.g., /T, /E, D/I, Line, HEXA). These systems are designed for architectural and commercial lighting applications, offering modularity, multiple mounting options, and advanced optical and control features.

1. Application Types and Mounting Options

• Trimless recessed installation
• Recessed with trim brackets
• Surface mounted
• Suspended (direct and direct/indirect)
• Wall mounted

The profiles accommodate ceiling thicknesses from 1 mm up to 25 mm depending on the model and mounting method, providing flexibility for diverse architectural requirements.

2. Optical Systems and Diffusers

• bGLARE: Microprismatic diffuser designed for high visual comfort and glare control.
• bLINE: Opal diffuser delivering soft, uniform light without visible spots.
• ASYM: Asymmetric diffuser optimized for wall washer applications.

These diffuser options enable tailored light distribution to suit various environments and lighting needs.

3. Product Characteristics and Performance

• Body: Extruded aluminium profiles with powder-coated finishes in White, Grey, and Black.
• Light Source: LED modules with CRI >80, MacAdam Step ≤3, and rated lifetime of 80,000 hours at L90 B10 (Ta 25°C).
• Control Gear: Integrated LED drivers compatible with 220-240V, 50/60Hz; options include HF, DALI, SwitchDIM, Tunable White, and emergency versions.
• Light Efficiency: High luminous efficacy ranging from approximately 87 lm/W up to 120 lm/W depending on configuration.
• Luminous Output: Varies by model and length, from about 1,396 lm to over 13,700 lm.

4. Modular System and Assembly

• Modular design allows continuous lighting lines up to 30,000 mm (30 meters) with a single feeding point for most models; some variants have shorter maximum lengths (e.g., 15,000 mm for REBA 50 D/I Line).
• Modules include start/end caps, middle modules, horizontal and vertical corners, edge corners, and body connector kits to ensure seamless mechanical and electrical connections without light leakage.
• Trimless recessed mounting kits feature frame alignment tools for precise installation and uniform line width across ceiling thicknesses (10, 13, 15, 18 mm).

5. Control and Emergency Lighting Options

• Double Circuit Switch: Enables separate control of direct and indirect lighting components.
• Emergency Units: 3-hour emergency lighting units (EM 3h K3) available for lengths typically ≥1402 mm.
• SwitchDIM Tunable White: Supports control of up to 20 luminaires for lengths ≤1682 mm and up to 10 luminaires for lengths ≥1964 mm; fewer luminaires can be controlled in combined direct/indirect versions.

6. Product Variants and Dimensions

• Length options range approximately from 560 mm to 2840 mm depending on model.
• Widths vary from 15 mm to 70 mm with cross-sectional dimensions such as 65x82 mm, 65x97 mm, and 77x82 mm.
• Variants include REBA 50 /T (trimless recessed), REBA 50 /E (recessed with brackets), REBA 50 D/I (direct/indirect), REBA 50 HEXA (hexagonal profile), and REBA 65 series with similar options.

7. Accessories and Installation Components

• End caps designed without visible screws and preventing light leakage, matching profile colors.
• Brackets for recessed mounting compatible with ceilings/walls up to 25 mm thick.
• Steel safety cables (1500 mm length) for suspension safety.
• Blank parts including inner profiles and aluminium blank covers for non-illuminated sections.
• Suspension kits with cables available in 1500 mm, 3000 mm, and 6000 mm lengths, with options for single or double cables.
• Ceiling roses in square and round shapes, surface mounted or recessed, with versions supporting DALI and emergency lighting integration.

8. Wiring and Electrical Schemes

• Standard wiring uses 3 x 1.5 mm² or 5 x 1.5 mm² cables depending on control gear and emergency options.
• Through-wiring and body connector kits facilitate continuous line installations with secure electrical and mechanical connections.
• Specific wiring configurations exist for HF+K3, DALI+K3, and K3+TEL control systems, including terminal blocks as needed.

9. Color and Finish Options

• Profiles are available in powder-coated White, Grey, and Black finishes to integrate with various interior designs.

10. Product Identification and Ordering Codes

• Product codes include placeholders (symbols) for specifying options such as color temperature (3000K, 4000K, Tunable White), emergency unit presence, control gear type, and color finish.
• Ordering requires separate purchase of inner profiles (symmetric or asymmetric), start kits, through-wiring kits, body connector kits, suspension accessories, and ceiling roses.

Critical Information and Best Practices

• Ensure correct selection and ordering of inner and outer profiles and diffuser types to meet lighting and installation requirements.
• Use trimless recessed mounting kits with frame alignment tools for precise installation and consistent line width.
• Consider emergency lighting options and control gear compatibility early in the design phase.
• Maximum continuous line length with a single feeding point is generally 30 meters; plan wiring and feeding points accordingly.
• Choose diffuser types based on application needs for visual comfort and light distribution (bGLARE for glare control, bLINE for uniform light, ASYM for wall washing).
• Verify ceiling thickness compatibility for the selected mounting system.
• Dimensions exclude start kits; add 6 mm to luminaire length when calculating recessing length.
• Emergency versions with DALI and 3-hour emergency units are only available for lengths ≥1402 mm; dimmable DALI versions without emergency units are not available in the shortest lengths (~562 mm).

Summary

The REBA aluminium profile lighting systems offer a versatile, modular, and high-performance solution for architectural lighting. They combine advanced LED technology with customizable optical systems, flexible mounting options, and comprehensive control and emergency features.
