Description
The ViewSonic LSD300W-ST is a short-throw, lamp-free projector built specifically for education environments. Third-generation LED technology delivers 3,300 ANSI Lumens with a 60,000-hour light source life, removing scheduled lamp replacement and mercury from the maintenance equation. A 0.49 short-throw ratio projects a 100" image from just 1.06m, keeping teachers clear of the beam and avoiding shadows on the board.
A 0.65" WXGA DMD chip gives a native 1280x800 resolution with an IP5X-sealed, filter-free optical engine for dust resistance and consistent colour over time. The projector supports 360-degree projection for ceiling, wall or floor installs, H/V keystone with 4-corner correction, instant power on/off, and LAN control compatible with Crestron, AMX, PJ Link, ATEN and Extron systems for centralised classroom management.
A 5V/2A USB-A output can power ViewSonic's ViewShare wireless casting dongle directly, and firmware updates are applied over USB without a service visit.

Planning from a real wall? Use the projector screen size calculator to upload a photo, preview the image to scale and find projectors that fit within your maximum available space. Replacing an existing projector? The projector replacement calculator checks whether this lens covers the ratio your current mount needs.
Distances are lens-to-screen, calculated from the manufacturer's stated throw ratio; allow for lens shift and mounting hardware. Always confirm against the manufacturer's installation guide before fixing mounts.
