Ultra-short throw installation
The model enables very short throw distances thanks to its 0.25:1 throw ratio, meaning a ~100″ screen can be achieved at very small lens-to-screen spacing. :contentReference[oaicite:2]{index=2}
Laser light source with long life
The AL-UK535A utilises a laser-phosphor light source (vs traditional lamp) providing a lifespan around 20,000 hours and offering lower maintenance for repeated exhibition deployments. :contentReference[oaicite:3]{index=3}
High colour performance via RGB primary-colour wheel
Appotronics applies a one-chip DLP system with an RGB 3-segment colour wheel that delivers a higher red ratio (16-18%) and fuller saturation compared to many 1-chip DLP systems (which may have red ~7%). This gives the AL-UK535A stronger colour accuracy and depth. :contentReference[oaicite:4]{index=4}
Sealed optical engine with dust-resistance
The projector features a fully sealed optical engine (from the light-source through the display-chip zone) rated to IP5X dust-ingress resistance, making it more reliable in installation and exhibition environments. :contentReference[oaicite:5]{index=5}
Rich I/O panel for integration
The model includes multiple HDMI inputs (three), USB ports, network (RJ-45) and RS-232 control, which supports integration into professional AV installations. :contentReference[oaicite:6]{index=6}
Fixed lens (no zoom) for simplified set-up
The AL-UK535A employs a fixed focal-length ultra-short throw lens without zoom capability, simplifying the optical alignment for wall-mount or table-top ultra-short throw installs. :contentReference[oaicite:7]{index=7}
Accessories
Remote control: included with the unit (standard Appotronics remote). Filter code & lamp part number: as the AL-UK535A uses a sealed laser engine with no user-replaceable lamp, a dedicated lamp part number is not applicable; for air-filter or maintenance replacement parts refer to Appotronics service documentation or contact authorised service provider.
