X-Range Interior

Available from 25W-40W

Manufactured from high quality aluminium with a natural anodized finish, the X-Range luminaires can withstand the most arduous of conditions whilst still maintaining high luminous efficacy through its toughened glass cover. An abundance of optics including narrow, medium and wide symmetric, asymmetric and counter beam distributions ensures that the X-Range luminaires can be designed in to any road tunnel project.
