Barbican: FOM Diamond – Architectural Fixture

February 10, 2026
FOM Diamond Linear Architectural Fixture Provides Effective Low-Glare Performance
Barbican’s FOM Diamond checks all the boxes for use in general lighting applications where performance, aesthetic, scale, design and budget are a concern. 2-Core LED technology provides excellent low-glare performance by delivering soft and even illumination on walls, and work surfaces while providing subtle up lighting to avoid the ‘cave effect’ of direct only fixtures.
The FOM system allows for many configurations to fit any space you have. Using the FOM linear system is a cost-effective alternative to traditional direct/indirect linear fixtures. Their multi-LED core on the direct side offers improved lateral light distribution for even horizontal light levels, as well as improved vertical illumination in a low glare and visually interesting form. Barbican’s unique hardware ensures your space feels considered and beautiful, while their QuickShip program helps you have your fixtures on-site, on-time.
