Ansell AVAS4/1/W/DD3 Vasco EVO 4ft CCT Multi-Wattage Bi-Directional DALI Dimmable LED Linear Light - White

The Ansell AVAS4/1/W/DD3 Vasco EVO is a modern, energy-efficient 4ft (1200mm) bi-directional LED linear luminaire designed for professional indoor lighting installations. Featuring a sleek white aluminium housing, selectable wattage, adjustable colour temperature and DALI dimming, this versatile fitting is ideal for offices, educational facilities, retail premises and other commercial environments.

Engineered to provide comfortable, evenly distributed illumination, the Vasco EVO features a 30% upward and 70% downward light output ratio. This combination of direct and indirect lighting helps illuminate work surfaces while enhancing ambient ceiling brightness. The supplied opal diffuser delivers smooth, uniform light distribution, making it particularly suitable for contemporary workplaces, classrooms and meeting areas.

With selectable 3000K warm white and 4000K cool white colour temperatures and adjustable power settings from 14W to 32W, the luminaire can be configured to meet different lighting requirements. It delivers approximately 105lm/W with the standard diffuser, while the optional AVAS4/1/UGR diffuser can increase luminous efficacy to an impressive 150lm/W.

Designed for convenient installation, the fitting includes adjustable suspension points, a suspension kit and a pre-wired 1.5m cable. Optional surface and track mounting accessories provide additional installation flexibility, while a compatible PIR end cap accessory is available for occupancy-based lighting control.
