Sapphire AR™ (Lighting)

Anti-reflective coatings on glass for lighting applications provide the highest light transmission to save energy. Sapphire by Groglass ensures that the maximum amount of light gets steered through the glass and illuminates with the highest efficiency. For outdoor lighting, this can mean significant energy savings by requiring less energy for the same lighting brightness. The top coating by Groglass ensures durable and maintainable glass products with exceptional quality.

Sapphire anti-reflective glass can improve the efficiency of most lighting objects that use glass as protection for the light source.
