About Polycarbonate Replacement Acorn Globes
Originally, transparent and translucent globes for commercial or industrial 
street lighting were made of glass.  Recently, plastic globes, commonly 
made from polycarbonate have come into widespread use.  Polycarbonate is 
75% lighter than glass, yet it's shatter proof, high impact strength helps to 
reduce vandalism. Our clear polycarbonate globes meet or exceed OEM specifications.  UV 
Stabilized and excellent light transmission add to the value of these 
replacement globes.
