Epson EB-815E 5,000 Lumens Full HD UST Laser Projector with 4KE, HDBaseT and PJLink

Epson EB-815E – Full HD UST laser projector with 4KE for schools and conferences

The Epson EB-815E is a professional ultra short throw laser projector with 5,000 lumens for training rooms, classrooms and conference rooms where there is no space for a long throw distance. With a throw ratio of 0.16–0.22:1, the EB-815E projects a large, bright image from less than 50 cm from the wall – without the presenter stepping into the beam and casting shadows. 4K Enhancement technology uses pixel shift to create a 4K UHD output – for considerably more detail in presentations and graphics. The laser light source delivers full brightness instantly, requires no lamp replacement and lasts up to 30,000 hours in Eco mode.

Applications: what the Epson EB-815E is ideal for

Classrooms and training rooms with mounting close to the wall

The EB-815E is designed specifically for rooms in which the projector is positioned directly above or in front of the projection surface. The throw ratio of 0.16–0.22:1 makes it possible to project a 100" image (approx. 2.2 m wide) from around 35–49 cm from the wall. This completely eliminates shadows cast by teachers or presenters – a decisive advantage over standard and short-throw projectors. 5,000 lumens ensure clear, legible projection even in rooms with daylight coming through windows.

Conference and presentation rooms with AV integration

For conference rooms integrated into a central AV control system, the EB-815E offers the full range of professional control protocols: PJLink, Crestron, AMX, Extron and Control4 enable integration into existing room automation systems without additional hardware. The web interface allows remote control and status monitoring via LAN. HDBaseT enables signal distribution over a single Cat6a cable up to approx. 70 m – ideal for rooms where the signal source is located far from the projector.

Multi-projector installations and digital signage

Using the edge blending function, several EB-815E units can be combined into one seamless, large projection – for wide video walls in auditoriums, congress centres or museums. Programmable scheduling switches the projector on and off at defined times without manual intervention. Direct start when mains power is applied also makes the EB-815E suitable for rooms where no remote control should be at hand.

Picture and sound quality

The EB-815E projects in Full HD (1,920 × 1,080) with 4K Enhancement technology, which uses pixel shift to create a 4K UHD output. As a 3LCD projector, it delivers identical colour and white brightness of 5,000 lumens – with single-chip DLP projectors, colour brightness can be well below the stated white brightness. HDR10 and HLG are supported.

Connections:

• 2× HDMI 2.0: for laptops, media players, video conferencing systems and signal distributors
• HDBaseT: HDMI signal, power and network communication over one Cat6a cable – conservatively up to approx. 70 m at Full HD; no separate HDMI extender needed
• LAN (RJ-45): Network control via web interface, PJLink, Crestron, AMX, Extron, Control4, SNMP, status monitoring
• RS-232: Control of power on/off, input selection, brightness, volume, freeze and status monitoring via serial interface
• 2× USB-A: power supply for external devices and media player operation
• Wi-Fi: optional via ELPAP11 dongle (2.4 and 5 GHz) with Miracast support; screen mirroring from Windows devices and Android smartphones without additional software

The split-screen feature shows two sources side by side at the same time – handy for comparison presentations or showing a laptop and a video conference simultaneously. The integrated media player supports MP4, AVI, MOV and MPEG with H.264/AVC, H.265/HEVC and MPEG-4 codecs, as well as image formats (JPEG, PNG, BMP, GIF) for playback without a connected source.

Mounting and installation

The EB-815E supports table placement, ceiling mounting (upside down) and rear projection. UST projectors are typically placed directly below the projection surface or mounted above the screen using a wall mount.

The projector supports image sizes from 80 to 160 inches.

Throw distance (guide values):

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

The fixed vertical offset (7:1) positions the image geometrically above the projection point – there is no free lens shift. For exact alignment when wall-mounting, the vertical distance between the unit and the projection surface must therefore be calculated in advance. Keystone correction (±3° vertical and horizontal) compensates for any remaining deviations – for fixed installations, exact mechanical alignment is recommended.

Security features: A Kensington lock eyelet and PIN lock protect the unit in public areas. Keypad lock prevents unauthorised changes; password protection additionally secures access.

The projector measures 695 × 341 × 156 mm and weighs 12.3 kg. Remote control, power cable and batteries are included in the box.

Running and follow-up costs

Power consumption: 380 W (Normal mode) / 183 W (standby active).

Light source:

As a laser projector, the EB-815E does not require regular light source replacement – low-maintenance in continuous operation.

Have you thought of everything?

• Screen: For UST installations, a flat projection surface is recommended. Fixed-frame screens offer maximum flatness; motorised screens are suitable for flexible use.
• Ceiling mount: Choose a suitable mount for ceiling installation – M4 mounting screws (10 mm screw-in depth). Projector ceiling mounts at a glance.
• HDBaseT transmitter: For signal paths beyond HDMI cable length, an HDBaseT transmitter transmits HDMI over Cat6a up to approx. 70 m (Full HD). PureLink 4K HDMI HDBaseT Transmitter with PoH.
• HDMI cable: No HDMI cable is included in the box. HDMI cables in our shop.
• Wireless presenting: EZCast Pro Dongle II (HDMI receiver for AirPlay, Miracast and Google Cast) or Kindermann Klick&Show K-FX for complete BYOD presentations in the conference room.
• Also available in white: The structurally identical Epson EB-810E has identical features and is intended for installations requiring a white housing.

Conclusion

The Epson EB-815E combines 5,000 lumens of brightness, 4K Enhancement and a genuine ultra short throw ratio with the full spectrum of professional control protocols. For schools, educational institutions and businesses looking for a shadow-free, low-maintenance projection solution that integrates into AV systems and offers enhanced sharpness, the EB-815E is a compelling choice – with a laser light source and a 5-year manufacturer's warranty as a reliable basis for continuous operation.
