Shat-R-Shield 40 Watts U-Shaped Fluorescent Lamp, T12, Medium Bi-Pin (G13), 2300 Lumens, 3500K Bulb Color Temp.

Shatter-resistant U-bend light bulbs have a coating on the surface of the bulb that keeps broken glass, mercury, and phosphors contained if the bulb bursts or breaks. This prevents safety hazards by keeping the contaminants from spreading into the surrounding area. These bulbs are installed in compatible lighting fixtures to provide general area lighting in manufacturing plants, food-processing facilities, and other environments where product contamination must be avoided. They are also used in areas where the light bulbs may be exposed to shaking or impacts, such as railway systems and freight elevators.
