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

The Ansell AVAS4/1/S/DD3 Vasco EVO is a high-performance 4ft (1200mm) bi-directional LED linear luminaire featuring a contemporary silver aluminium finish. Designed for commercial, educational and retail environments, this versatile lighting solution combines selectable wattage, adjustable colour temperature and DALI dimming to provide efficient, adaptable illumination for modern indoor spaces.

Featuring an innovative 30% upward and 70% downward light distribution, the Vasco EVO creates a balanced lighting environment by illuminating both the working area and surrounding ceiling. The supplied opal diffuser provides smooth, uniform light output, helping to enhance visual comfort in offices, classrooms, meeting rooms and retail premises. A downward-only lighting option is also available, although this changes the overall light output.

With selectable 3000K warm white or 4000K cool white colour temperatures and adjustable power settings between 14W and 32W, this LED linear fitting offers excellent flexibility for different lighting requirements. Delivering approximately 105lm/W with the standard diffuser, efficiency can increase to 150lm/W when fitted with the optional AVAS4/1/UGR diffuser.

The luminaire is supplied with a 1.5m pre-wired cable, adjustable suspension points and a suspension kit for convenient installation. Optional accessories allow surface or track mounting, making the Ansell Vasco EVO a practical lighting choice for new installations and refurbishment projects.
