HOW TO READ THE ILLUMINATION VALUES

For a quick overview, the illumination values in the following tables are color coded. There are many factors that determine the visibility of a projection, such as ambient light, color and reflectiveness of the projection surface, competing light, gobo colors, projector color temperature, and other factors. Therefore our recommendations should only be used as guidelines and we cannot guarantee a successful application. If you are unsure, please call us to discuss your application. 

Sufficient brightness for bright environments, such as Office-, Lobby-, Retail-, Trade Show-, Conference Environment, Outdoors (shady, no direct sunlight). Color gobos project in vibrant colors.   

Sufficient brightness for darker environments, such as bars, clubs, and intimate restaurants, theaters, and conference rooms. Outdoors only visible at night. Color gobos should preferably be used with lighter colors and the projection surface should be light and somewhat reflective.

Only advisable for dark environments and subtle projection of light colored artwork, preferably on light, reflective projection surface.
