March 11, 2013 – GE says its Lumination BL Series LED luminaires help free lighting professionals from the constraints of traditional T-grid ceiling designs. They were designed and tested specifically for the Logix ceiling system from USG, says GE, and are compatible with most other integrated ceiling systems. This gives designers the freedom to create ceilings with a clean, finished appearance, says the company, while retaining the functionality of a T-grid system for standard maintenance of HVAC, electrical and plumbing systems. Lumination BL Series LED luminaires promise up to 39% improved energy efficiency opposed to traditional fluorescent lighting, says GE, and are available in 4-ft and 5-ft lengths measuring 4-in. or 6-in. wide, and come prepared with adaptable mounting brackets for compatibility with different integrated ceiling systems.
