Description
The EF-21G is the green finish of Epson's EF-21 mini laser projector: a 2.3kg cube that puts a 30 to 150-inch picture on a wall from a short distance and runs its own apps, with no source device required. Google TV is built in, with Chromecast and Google search on board.
Picture comes from 3LCD with a laser light source rated at 1,000 lumens of both white and colour light output, which is the specification that matters for a projector expected to hold colour saturation in a room that is not fully blacked out. Contrast is quoted at 5,000,000:1 and the throw ratio of 1.00-1.82:1 puts a 60-inch image at about 1.33m.
Setup is automatic: keystone correction, focus by motor, and instant on/off. A 5W stereo speaker and an HDMI ARC port let it act as the only box in a small room, and Epson covers it with a 60-month carry-in warranty or 12,000 hours, whichever comes first.
Key features
Runs streaming apps, Chromecast and Google search on the projector itself, so no stick or laptop is needed.
3LCD delivers 1,000 lumens of colour light output as well as 1,000 lumens white, so colours do not wash out as they can on single-chip designs.
No lamp to replace, with instant on and off rather than a warm-up and cool-down cycle.
Motorised focus and automatic keystone correction square the image up without manual adjustment.
