With its fixed throw ratio of 0.49:1, it creates a 100-inch image from a distance of just around 1.08 m, without the presenter casting a shadow into the beam. The LED light source lasts up to 30,000 hours and is designed for 24\/7 operation, so running costs are fixed from the start. Common control protocols such as PJLink and Crestron integrate it directly into existing room control systems.\u003c\/p\u003e\n\n\u003ch3\u003eBenefits and special features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eShort-throw lens with TR 0.49:1 – 100\" image from approx. 1.08 m, no presenter shadow\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e3,300 ANSI lumens for easily legible content even with the room lights on\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eLED light with 30,000 hours of life: no light source replacement, predictable running costs\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e24\/7 operation and 360° installation: approved for ceiling, wall and portrait orientation\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003ePJLink Class 1, Crestron, AMX, Extron and Telnet for full network control\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eWall colour correction projects colour-accurately directly onto tinted walls without a separate screen\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eScheduled start on mains power and on HDMI signal for unattended roll-outs\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eIs the Optoma LH351ST the right choice?\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eYes,\u003c\/strong\u003e for permanent installations in meeting rooms and classrooms with little room depth, for digital signage in continuous operation and anywhere a low-maintenance LED light source should keep running costs predictable.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNot ideal,\u003c\/strong\u003e if you are filling very large or bright surfaces and need more light output – in that case, consider brighter \u003ca href=\"\/en\/collections\/kurzdistanz-beamer\"\u003eshort-throw laser projectors\u003c\/a\u003e .\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNot suitable,\u003c\/strong\u003e if you need more flexibility when mounting – larger \u003ca href=\"\/en\/collections\/installationsbeamer\"\u003einstallation projectors with lens shift\u003c\/a\u003e are the way to go.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eUnsure about room size or mounting point? \u003ca href=\"\/en\/pages\/kontakt\"\u003eGet in touch →\u003c\/a\u003e\u003c\/p\u003e\n\n\u003ch3\u003eApplications: what the Optoma LH351ST is ideal for\u003c\/h3\u003e\n\n\u003ch3\u003eMeeting and conference rooms with little room depth\u003c\/h3\u003e\n\u003cp\u003eIn meeting rooms that are too shallow for a standard-throw projector, the LH351ST delivers an 80-inch image from a wall distance of just around 0.87 m.

The 3,300 ANSI lumens are sufficient for medium-sized rooms with some daylight when the windows are partly darkened.

The fixed image offset (107 %) shifts the centre of the image by around 7 % of the image height relative to the lens axis.

The 30,000-hour life and approval for 24\/7 operation make it an economically predictable solution for meeting rooms, classrooms and digital signage. PJLink, Crestron, AMX and Extron natively cover the common control protocols of professional AV infrastructures. The fixed lens with TR 0.49:1 fits rooms where standard-throw projectors cannot work due to their design.\u003c\/p\u003e\n\u003cp\u003eFrom single unit to complete system: we plan your turnkey projector solution including suitable accessories and integration.
