One of the great innovations of recent years in home entertainment projector technology has been the LED/Laser light source. It’s that which allows the new Epson EF-100B home entertainment projector to be so very flexible.


Before getting to that, I should mention that there’s also an Epson EF-100W projector which is identical, except that it is finished in white and has silver highlights (pictured above). The Epson EF-100B is black and has copper highlights.

Epson EF-100B

This projector has been designed with ease of use in mind. It is stripped down to essentials, and presented in a nice rectangular package that’s only 210mm wide, 227mm deep and 88mm tall. It feels like a brick, weighing 2.7 kilograms.

The lens is inset into the body. It doesn’t zoom – there is a digital zoom, but that just scales the image down to a smaller size. The net effect is reduced resolution. Both vertical and horizontal keystone adjustments are provided. These can be used to straighten up the image if the projector has to be placed at an angle. Again, these reduce resolution.

As you may have by now sensed, I am against anything that reduces resolution, so I’d strongly suggest that the projector should be placed in the right position, square to the projection screen. For a 100-inch screen, that’s at a distance of 3.05 metres, raised slightly above the bottom of the screen.

That’s me being all purist, of course. Clearly, Epson expects the Epson EF-100B projector to be used in an ad hoc way, projecting against a wall or other convenient flat surface.

For, for that matter, against a ceiling.

Epson EF-100B light source

Most projectors use an incandescent lamp as their light source. A powerful one, of course, carefully designed to produce the right colour of light for the best final result. But because they are powerful, they are also fragile and they tend to expire after a few thousand hours of use.

And they generally have to operate with the projector placed horizontally, either on a desktop or upside down attached to a ceiling mount. Run them at other angles and it puts life-shortening stress on the lamp’s filament.

The Epson EF-100B employs the much newer LED/Laser technology. These generally work as follows: a powerful LED laser emits a narrow wavelength of blue light. That strikes a carefully chosen phosphor which responds by glowing brightly with white light. So, it’s a solid-state lamp and thus more robust (although usually a ring of phosphor is used on a spinning wheel to help manage heat).

You can put the projector so that it fires directly upwards, or put it on its side so it’s running in portrait rather than landscape mode.

LED/laser lamps are also longer-lived. Conventional lamps usually have a rated life of up to around 4,000 hours in normal mode, longer in low power modes. The lamp in the Epson EF-100B is rated at up to 12,000 hours in normal mode, and up to 20,000 hours if running at 50% output.

Another advantage of LED/Laser lamps is fast on/fast off. They can generally switch on and off instantly. With this projector, it takes five or six seconds for the electronics to get going.

Epson EF-100B Connections

The Epson EF-100B appears, at first glance to have no inputs. But there’s a panel on the back which can be removed. Behind that is a space for the built-in speaker. Also in there is a HDMI socket on a short cable and a USB Type-A socket, intended for providing power for accessories. The review unit already had inside an Amazon Fire TV Stick. There’s enough space in there to instead use a Chromecast device.

A hole on the side also lets you feed in a HDMI cable. That’s how I used it, feeding content from my UltraHD Blu-ray player (at full HD resolution). But I really like the idea of being able to tuck a wireless streaming dongle away inside. There’s something cool about being able to just plug the projector into power and then use your Netflix or whatever app on your phone to send movies to it. It would also work fine with the Microsoft Wireless Display Adaptor.
