Eiki EK-308ST-B
Higher Brightness in a Compact Body, now with a short-throw lens
The EK-308U possesses the highest brightness among Eiki's portable projectors. Equipped with a variety of input and output terminals on its compact body (including HDMI, VGA, LAN and RS-232C), it displays bright and clear images, making it a perfect choice LCD projector short-throw applications.
With this 5600 lumen projector, maintenance is easy thanks to a top-accessed lamp and side-accessed filter. This Eiki projector has an electrostatic filter, providing highly effective filtration for increased dust protection.
Horizontal and vertical lens shift, keystone correction, and corner correction allow flexible installation in a variety of situations. The EK-308U portable projector is suitable for golf simulators and other small to medium-size rooms where a short-throw lens is needed. By removing the conversion lens from the primary lens, the projector can also be used for standard-throw applications (1.07-1.75:1).
