Alfa Z direct/indirect

Alfa Z's elegant and timeless design creates a cosy atmosphere in offices, restaurants, shops and schools.

Alfa Z direct/indirect is suitable for task lighting and school lighting thanks to the separately controlled upper and lower luminaires. Allows adaptable modular queue and perimeter solutions. Extension profiles allow the installation of target luminaires on an integrated light rail.

Application area: lobbies, offices, open offices, schools, shops and hospitals

Installation: hanging

Benefits

Ease of design:

3000K, 4000K and 5000K CRI 80 and CRI 90 versions with the same luminous intensity. CRI 90 versions have approximately +20% higher luminaire wattage. This makes design easier, as any light colour or colour rendering can be selected without the need to constantly update the lighting design.

Design language, colour and texture:

The luminaire represents an elegant Finnish minimalist cutting-edge design and blends seamlessly with the rest of the architecture. The basic colours of the luminaire, with its aluminium body, are white (RAL 9003) or black (RAL 9005) with metallic effect coating. The ends of the luminaire are polycarbonate with a metallic effect finish. Additional colours red (RAL 3020), yellow (RAL 1016), grey (RAL 9006), and green (RAL 6018) are standard. Other colours according to RAL chart (additional colours always with black heads and optics). The upper surface of the luminaire is easy to clean.

Carbon footprint:

Alfa Z dark light office luminaires have a very low carbon footprint. This is made possible by high quality LEDs with an efficiency of over 230 lm/W (CRI 80) and a "Design in Finland" optic with an efficiency of up to 94% (white version).

Applicability

Offices, schools, restaurants, cafés, shops and stores.

* 50/50 and 40/60 versions with bottom and top light provide glare-free lighting meeting EN 12464: VDU L65 ˂1500cd/m² and VDU L65 ˂3000cd/m² requirements

* The bottom and top light of the 30/70 version provides good vertical illumination for biological lighting. EN 12464: VDU L65 ˂1500cd/m² + Evm 280lx

* The 75/25 version can provide efficient and glare-free general illumination with a small amount of overhead light

* The designer can tailor the luminaire and choose between direct downlighting and a separate indirect overhead lighting from 1000-7000 lm. The product is supplied pre-programmed. The customisation allows for a tailor-made solution that takes into account both biological and visual lighting requirements.
