Hello Jill. Yes, the Epson Lifestudio Flex Plus projector is designed for both indoor and outdoor use. It should only be used outdoors in dry environments, ideally at night or in shaded areas, and must be protected from rain, humidity, and dust. A stable power source with outdoor‑rated cords is recommended, and pairing it with a proper screen will improve performance. We recommend reviewing the User Guide for more details on operation altitude and temperatures. Regards, Kevin - The Epson Team.
