Strengthened (tempered) glass has successfully been fielded in indoor and outdoor lighting applications for > 50 years to provide translucent properties as well as long-term mechanical strength and durability (thermal, chemical, and environmental). Glass has proved to be the best long-term material choice to protect the valuable components of a lighting fixture (light source, reflectors, electronics, etc.) from the elements in architectural lighting applications. Unlike other materials, glass does not carry a static charge that attracts dirt and does not degrade to the intense and prolonged UV exposure seen in outdoor lighting applications. Tempered glass is a lost-cost and readily available material option that can be easily and cost-effectively converted into end fabricated part based on the light application’s need.
