Verdict

The Epson EF-100B is a compact, portable 3LCD laser projector featuring 2,000 lumens of both color and white brightness and a native WXGA (1280 x 800) resolution. It utilizes MicroLaser Array Technology for vibrant images up to 150 inches and boasts a long-lasting light source rated for up to 20,000 hours in Eco mode. Main pros include its sleek, lightweight 2.7kg design, high 2,500,000:1 dynamic contrast ratio for deep blacks, and the inclusion of an Android TV dongle for seamless streaming with built-in Google Assistant. However, notable cons include its relatively low resolution compared to modern 1080p or 4K standards, lack of HDR or 3D support, and limited connectivity with only a single HDMI port.
