Epson EB-L210W laser projector WXGA, 4500 ANSI lumens, 2 × HDMI, Wi-Fi

The EB-L210W is an Epson wireless laser projector. It has no conventional lamp that dims with use and has to be replaced from time to time. That cuts maintenance and suits rooms where the projector runs for several hours every day. Epson does not list the light source life in hours for this model.

At 4500 ANSI lumens it is the brightest model in this series: according to Epson, the EB-L210SW and EB-L210SF deliver 4000 ANSI lumens. The extra light helps when the image is large or the ceiling lights stay on while people take notes. Direct sunlight on the screen still lowers contrast on any projector, so curtains help.

A throw ratio of 1.41–2.26:1 means image width is roughly the distance divided by that number. From three metres the image is about 1.3–2.1 m wide, from five metres about 2.2–3.5 m. The range lets you reach the same image size from different distances, so the projector can go on an existing ceiling mount.

A resolution of 1280 × 800 in 16:10 pairs well with laptops, many of which also have 16:10 screens, so a presentation fills the image without wide black bars. Slides and tables are easy to read at this resolution. The rated contrast of 2,500,000:1 helps separate dark tones in a dimmed room.

Two HDMI inputs let you keep, for example, the room PC and a presenter’s laptop connected and switch between them without swapping cables. Built-in Wi-Fi joins the projector to a wireless network without a separate adapter, which is handy when it hangs from the ceiling far from the tables. Epson does not list any other inputs in this data.

The EB-L210W suits meeting rooms, classrooms and smaller lecture rooms where the projector is ceiling-mounted in the middle or at the back and used every day. If the projector has to sit right next to the screen while the presenter moves in front of the image, the short-throw EB-L210SW is the better fit.
