Epson EB-685W – ultra short throw projector for shadow-free presentations in the classroom

The Epson EB-685W is a powerful 3LCD ultra short throw projector developed specifically for schools and training rooms. With a throw ratio of 0.28–0.37:1, it projects a large, evenly illuminated image from less than one metre from the wall – presenters and pupils never stand in their own shadow. The WXGA resolution of 1,280 × 800 pixels displays 16:10 laptop content edge to edge, without black bars. With 3,500 ISO lumens, presentations remain easy to read even in rooms with normal ceiling lighting.

Benefits and special features

3,500 ISO lumens – equal white and colour brightness thanks to 3LCD technology
Ultra short throw lens (TR 0.28–0.37:1) – no shadows cast by presenters
WXGA 1,280 × 800 – 16:10 format without letterboxing for standard laptops
3× HDMI 2.0 – several sources connected at the same time
LAN with PJLink, Crestron, AMX and SNMP – central network control and monitoring
RS-232 for room control integration (on/off, input, brightness, status)
Direct Power On – starts automatically as soon as mains power is applied
36-month warranty

Applications: what the Epson EB-685W is ideal for

Classrooms and teaching rooms

The ultra short throw lens of the EB-685W allows wall mounting directly above the board or placement on a table at the front of the classroom. Teachers never stand in the beam of light – they can interact freely with the projected content at any time. 3,500 ISO lumens reliably outshine normal room lighting, so there is no need to lower the blinds.

Training rooms and meetings

With three HDMI inputs, a laptop, desktop PC and another device can stay connected at the same time – switching between presenters works without hunting for cables. The 16:10 format displays Office presentations and spreadsheets in full. The LAN connection with PJLink protocol enables central control and monitoring via the school network, so teachers don't have to search for the remote control.

Picture and sound quality

The EB-685W uses Epson's proven 3LCD technology with a 0.59" chip. The native WXGA resolution (1,280 × 800 pixels) matches the 16:10 format of current laptops – presentations, spreadsheets and web content are displayed without scaling losses. With a contrast ratio of 14,000:1, text and diagrams stand out clearly. As a 3LCD projector, the EB-685W delivers identical white and colour brightness of 3,500 ISO lumens; with single-chip DLP projectors, colour brightness can be significantly lower than the stated white brightness.

The built-in 16 W mono speaker is sufficient for regular lessons and training rooms. For larger groups or more demanding room sound, an external audio output is available.

Connections and connectivity:

3× HDMI 2.0 – for laptop, PC and other sources at the same time
LAN (RJ-45): network control via web interface, PJLink, Crestron, AMX, Control4 and SNMP – status monitoring and central management via the school network
RS-232: control of on/off, input selection, brightness, volume, freeze and status queries – for room control systems
USB-A: 1× for powering accessories or peripherals
Wi-Fi: optional via ELPAP10 adapter (2.4 GHz) – wireless presentation via the Epson iProjection app for up to 4 devices at once

Setup, mounting and in the box

The throw ratio of 0.28–0.37:1 allows wall mounting with a ceiling or wall mount directly above the projection surface, as well as table placement at the front of the room and rear projection. Thanks to the fixed, significantly upward image offset, the projector can be placed just above or below the projection surface without protruding into the image. UST projectors should always be aligned exactly parallel to the wall – the digital keystone correction (±3° vertical/horizontal) is only intended for fine-tuning minimal residual deviations and is no substitute for proper mechanical alignment.

UST projectors are typically placed directly below the projection surface or wall-mounted above the screen. Many models also support upside-down ceiling operation – please refer to the manual for the mounting options of the respective model.

The calculated throw distances are based on the manufacturer's throw ratio and are intended as guide values. As the measuring points (e.g. from the centre of the lens vs. the front of the housing) often vary between data sheets, calculations accurate to the centimetre cannot always be guaranteed.

Image size	Image width	Image height	Throw distance (approx.)
80"	171 cm	107 cm	48–63 cm
100"	214 cm	133 cm	60–79 cm
120"	256 cm	160 cm	72–95 cm

In the box: Epson EB-685W, remote control, power cable, batteries.

Light source and operation

Operating mode	Lamp hours	Years (2 hrs/day)	Years (8 hrs/day)
Normal	5,000 h	7 years	1.5 years
Eco	10,000 h	13.5 years	3.5 years
Dynamic	9,000 h	12.5 years	3 years

In Eco mode, the noise level drops from 35 dB to 30 dB – a clearly measurable difference that noticeably improves quiet lessons. Power consumption falls from 301 W to 258 W. Standby consumption is 0.37 W. For installations where the projector should start automatically when the room's power supply is switched on, the EB-685W offers the Direct Power On function: it starts without pressing a button as soon as mains power is applied.

The replacement lamp (ELPLP91) is available from specialist retailers. If you would rather avoid lamp changes in the long term, Beamer-Discount also offers laser UST models with comparable specifications.

Epson EB-685W – ideal for schools, training rooms and continuous presentation

For institutions with several projectors, the EB-685W offers extensive management functions: the start-up logo can be replaced with your own school logo. The keypad lock prevents unwanted tampering by pupils – operation remains possible via the remote control only. Freeze Frame freezes the image while the laptop is being changed or prepared. Password protection and a Kensington slot protect the unit against unauthorised access and theft.

If you are looking for a lower-maintenance alternative to a lamp-based model, the Epson EB-770F is a laser UST projector with 4,100 ISO lumens, Full HD resolution and up to 30,000 hours of operation without lamp changes.

Have you thought of everything?

Wall mount – for mounting directly above the board or screen
Ceiling mount – for upside-down ceiling mounting close to the projection surface
HDMI cable – for using all three HDMI inputs at the same time

Conclusion: education projector with full network integration

The Epson EB-685W combines an ultra short throw lens, 3,500 ISO lumens of brightness and full network control in a field-proven education projector. Shadow-free projection, easy wall mounting and direct integration into Crestron and PJLink environments make it a reliable choice for schools and educational institutions. If your environment requires more lumens or you would prefer a maintenance-free laser light source, we will be happy to advise you.
