There aren’t many products on the market that are so powerful that they require the technicians to take a special certification course by the U.S. Food and Drug Administration (FDA), but the Sony VPL-GTZ380 projector is not just any product.
Since its debut last February as the company’s latest flagship projector early last year, the $88,000 Sony GTZ380 has quickly become a favorite for many top integrators due to its impressive 10,000-lumen light output that offers dealers the flexibility to install it is varying ambient light conditions.
